web api assignments

Assignment 1: Build your own API

Build your own api – due monday, march 9th.

In this assignment you will be tasked to build your own server that will serve as an API. You will be building a fully functional server that could, if deployed to the cloud, serve real live internet traffic and be integrated as a part of a web application.

You will be building a server that can keep track of tasks. Your server must be able to do the following:

Create a new task with a title property and a boolean determining whether the task has been completed. A new unique id would be created for each new task

List all tasks created

Get a specific task.

Delete a specified task

Edit the title or completion of a specific task

(Extra Credit) Bulk add multiple tasks in one request
(Extra Credit) Bulk delete multiple tasks in one request

Your application will accept JSON and/or URL parameters and will return JSON data. Your server would be ready to be automatically integrated in a web system.

List of endpoints to be created

Here is a specific list of endpoints that you will be required to create, along with the method and the inputs/outputs:

Create a new Task

The id returned is a unique id for the todo that was just created

Delete a specific task

Notes: This endpoint deletes a specific task. If the task doesn’t exist still send the same response

Notes: This endpoint deletes a specific task or returns a 404 not found response

(Extra Credit) Bulk add tasks

Notes: This endpoint bulk adds more than one task. Note that this feature uses the same endpoint as the single task creation endpoint

(Extra Credit) Bulk delete tasks

Notes: This endpoint bulk deletes more than one task.

To see if you are on the right track, run the below file (using pytest, while your server is running) to test your endpoints. This is not an extensive test.

This test is to ensure that you have all of the routes correct and that your response is properly formed. For example, ensuring that your GET /v1/tasks/{id} endpoint returns a dictionary with an id (a number), a title (a string), and whether the task is completed (boolean).

Note: please run this as the first thing that hits your server on boot up. If it successfully completes once then your assignment is on the right track. Re-running the tests could fail as written.

So in short:

Start your webserver
Run your tests once
If pass you are good!

Please use the repository you created in week2. You will need to add all of your code to that repository and use the git commands to stage, commit, and push your code to GitHub. Please check that lab’s instructions to make sure you are set up and ready to go.

Please submit the URL of your repository to BCourses. This is important so that we know whose repository is whose in the class.

ASP.NET Core Web API Tutorials

This ASP.NET Core Web API Tutorial will cover all the ASP.NET Core Web API concepts with real-time examples. You will learn from the basic to advanced features of ASP.NET Core Web API as you progress in this ASP.NET Core Web API Tutorial Course.

This ASP.NET Core Web API Tutorial is For whom:

This tutorial is designed for Students, Beginners, Intermediate, and Professionals Software Developers who want to learn ASP.NET Core Web API step by step from very basics to advanced level concepts. This ASP.NET Core Web API Tutorial provides a hands-on approach to the subject with step-by-step program examples that will assist you in learning and putting the acquired knowledge into practice.

Why do we need Web APIs?

Suppose you have an idea to develop and launch a product. For this, you need to develop a website and launch this product. Then what will you do? You will develop a website using any web technologies like ASP.NET MVC, PHP, ASP.NET Core, JSP, etc., that are available on the market. Of course, you will need a database, such as MySQL, Oracle, SQL Server, etc., to store your product’s business data.

So, by combining the website and the database, you will have a fully functional, dynamic website that interacts with the database. Now, after some time, your business grows. Now, along with the website, you also want Android and iOS apps. That means you want three different applications (Website, Android, and iOS) for your business. But remember, you only have one database in the backend, which stores the entire business data. So, we have three different applications and one database. So, all these three applications have to interact with the database, as shown in the below image.

If all three applications interact directly with the database, we have some problems. Let us understand the problems first, and then we will see how to overcome the above problems.

Problems Without Web APIs:

Duplicate logic for each Application: The business should have some business logic. We will write the same logic for each application type, which means repeating the same logic for each type of application. This will duplicate our code.
Error-Prone Code: The business logic has been written in each type of application. We have to write the code in three different applications in our example. So, you might miss some code or logic in some applications. This will add more errors to your application.
Some Front-end frameworks cannot communicate directly with the Database: If you are developing the website (i.e., front-end) using the angular framework, then the angular framework cannot communicate with the database directly. Angular is a front-end framework.
Hard to Maintain: This type of structure is hard to maintain. This is because we have written the code in many places, and if we want to improve something in our application, we need to do the same thing in many places.

There are also lots of other problems that we face in this structure. Let us see how to overcome the above problems, or we can say why we need Web APIs.

Need for Web APIs:

As you can see in the image below, we have three applications on the left-hand side, and on the right-hand side, we have the database.

We aim to establish communication between all these three applications and the database. So, what will we do? We will add a new Web API Project. This Web API Project will interact with the database. All three applications will only interact with the Web API Project, as shown in the below image.

So, the Website, Android, and iOS applications do not have direct access to the database. They only need to communicate with the Web API Project, and it is the Web API project’s responsibility to interact with the database. The entire business logic will be written in the Web API project only, so we need Web API for our project. So, Web API acts as a mediator between the Front-End and Back-End.

Advantages of Web API:

Using Web API, we can avoid code duplication: We can write the logic in one place, i.e., in our Web API project, and all applications will use that logic.
Extend Application Functionality: Suppose, first, we develop the website. Then, we can extend and develop an Android App. Again, in the future, if you want to add another type of application, we don’t have to write any logic.
Abstraction: We have added an extra abstraction layer as we have written all the business logic in our Web API project. The logic we wrote in the Web API project will not be visible to the front-end developers.
Security : None of the applications can access the database directly, and hence it provides security.

What is Web API?

API stands for Application Programming Interface. Web API is a concept (not a technology) that works on the HTTP Protocol and is used to extend the functionality of an application.

A Web API, or Web Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate with each other over the internet or a network. It enables the exchange of data and functionality between various systems, using HTTP (Hypertext Transfer Protocol) as the communication protocol.

Key Characteristics of Web APIs:

HTTP-Based Communication: Web APIs are designed to work over HTTP, the same protocol used for Web Browsing. This means APIs can be accessed using standard HTTP methods like GET, POST, PUT, DELETE, etc. The API endpoints are typically represented as URLs (Uniform Resource Locators).
Data Exchange Formats: Web APIs use standardized data exchange formats such as JSON (JavaScript Object Notation) and XML (Extensible Markup Language) to structure and transmit data between the client and server. JSON has become the most popular format due to its simplicity and ease of use.
RESTful Architecture: Web APIs are designed to follow Representational State Transfer (REST) principles. A RESTful API is stateless, uses standard HTTP methods, and organizes resources into a hierarchy with unique URLs for each resource.
Authentication and Authorization: Web APIs implement security mechanisms for authentication and authorization to ensure that only authorized clients can access resources or perform specific actions. Common authentication methods include API keys, OAuth, and JWT (JSON Web Tokens).

What is ASP.NET Core Web API?

ASP.NET Core Web API is a framework for building scalable and high-performance Restful Web Services (APIs) using the ASP.NET Core platform. It allows developers to create robust and flexible APIs that various clients can consume, such as web applications, mobile apps, desktop applications, and third-party services.

ASP.NET Core Web API is commonly used for building RESTful APIs that expose data and services over HTTP. It’s suitable for various scenarios, including building back-end services for web, mobile, and desktop applications, providing data to single-page applications (SPAs), and creating microservices that can be deployed independently.

Prerequisites to Learn ASP.NET Core Web API

Learning to develop with ASP.NET Core Web API involves understanding general development concepts and specific technologies related to Web API development. Here are the prerequisites you should cover before diving into ASP.NET Core Web API:

Basic Knowledge of C#: ASP.NET Core is built on C#, so a solid understanding of C# programming is essential. You should be comfortable with C# syntax, basic programming constructs like loops and conditionals, classes and objects, and more advanced concepts such as LINQ, async/await, and exception handling.
Understanding .NET Core Basics: Familiarity with the .NET Core framework is important. This includes understanding the .NET Core CLI, the structure of .NET Core applications, basic concepts like dependency injection, and how to use NuGet packages.
Understanding HTTP/HTTPS Protocols: Understanding how client-server communication works using HTTP methods (GET, POST, PUT, DELETE).
Understanding of RESTful Services Principles: Grasping the basics of REST, including statelessness, resource identification, and standard HTTP methods.
Understanding of JSON/XML: Familiarity with JSON and XML, which are commonly used for data exchange in web services.
Familiarity with Entity Framework Core: Entity Framework Core (EF Core) is the recommended ORM for data access in ASP.NET Core applications. Understanding EF Core for performing CRUD operations with databases is highly beneficial.
Basic Database Knowledge: Basic knowledge of databases, especially relational databases like SQL Server, MySQL, or PostgreSQL, is important. You should know how to design databases, write basic SQL queries, and understand concepts like tables, keys, and relationships.
Front-end Technologies (Optional but Helpful): While not strictly necessary for backend development, basic knowledge of front-end technologies like HTML, CSS, and JavaScript can be helpful, especially if you plan to work on full-stack applications. Familiarity with a JavaScript framework like Angular, React, or Vue.js is a plus.
Understanding of MVC Architecture: While ASP.NET Core Web API is more focused on APIs, understanding the MVC (Model-View-Controller) pattern, commonly used in ASP.NET Core applications, can be beneficial.
Basic Knowledge of Software Design Principles: Understanding basic software design principles, such as SOLID Principles and design patterns, can be advantageous in writing clean, maintainable, and scalable code.
Familiarity with Development Environments: Experience with an integrated development environment (IDE), preferably Visual Studio or Visual Studio Code, widely used for ASP.NET Core development.

A Web API is a developer's dream.

It can extend the functionality of the browser
It can greatly simplify complex functions
It can provide easy syntax to complex code

What is Web API?

API stands for A pplication P rogramming I nterface.

A Web API is an application programming interface for the Web.

A Browser API can extend the functionality of a web browser.

A Server API can extend the functionality of a web server.

Browser APIs

All browsers have a set of built-in Web APIs to support complex operations, and to help accessing data.

For example, the Geolocation API can return the coordinates of where the browser is located.

Get the latitude and longitude of the user's position:

Third Party APIs

Third party APIs are not built into your browser.

To use these APIs, you will have to download the code from the Web.

YouTube API - Allows you to display videos on a web site.
Twitter API - Allows you to display Tweets on a web site.
Facebook API - Allows you to display Facebook info on a web site.

Best practices for REST API security: Authentication and authorization

If you have a REST API accessible on the internet, you're going to need to secure it. Here's the best practices on how to do that.

Most apps that use a modern web framework will have one or more REST APIs . REST is a simple and flexible way of structuring a web API. It’s not a standard or protocol, but rather a set of architectural constraints.

There are three reasons you might find yourself writing a REST API:

To give a networked client that you built—for instance, a single-page app in the browser or on a mobile app on a phone—access to data on your server.
To give end users, both people and programs, programmatic access to data managed by your application.
To let the many services that make up your app's infrastructure communicate with each other.

Any API built for these reasons can be abused by malicious or reckless actors. Your app will need an access policy—who can view or modify data on your server? For instance, only the author [ Editor’s note: the editors, too] of a blog post should be able to edit it, and readers should only be able to view it. If anyone could edit the post you’re reading, then we’d get vandals, link farmers, and others changing and deleting things willy nilly.

This process of defining access policies for your app is called authorization. In this article, we'll show you our best practices for implementing authorization in REST APIs.

Always use TLS

Every web API should use TLS (Transport Layer Security). TLS protects the information your API sends (and the information that users send to your API) by encrypting your messages while they're in transit. You might know TLS by its predecessor's name, SSL. You'll know a website has TLS enabled when its URL starts with https:// instead of http://.

Without TLS, a third party could intercept and read sensitive information in transit, like API credentials and private data! That undermines any of the authentication measures you put in place.

TLS requires a certificate issued by a certificate authority, which also lets users know that your API is legitimate and protected. Most cloud providers and hosting services will manage your certificates and enable TLS for you. If you host a website on Heroku, enabling TLS is a matter of clicking a button. If you host on AWS, AWS Certificate Manager combined with AWS Cloudfront will take care of you. If you can, let your host manage your certificates for you—it means no hassle at all and every API call will be automatically secured.

If you're running your own web server without any third-party services, you'll have to manage your own certificates. The easiest way to do this is with Let's Encrypt, an automated certificate authority. Let's Encrypt has a helpful getting started guide .

Use OAuth2 for single sign on (SSO) with OpenID Connect

Nearly every app will need to associate some private data with a single person. That means user accounts, and that means logging in and logging out. In the past, you may have written login code yourself, but there's a simpler way: use OAuth2 to integrate with existing single sign-on providers (which we'll refer to as "SSO").

SSO lets your users verify themselves with a trusted third party (like Google, Microsoft Azure, or AWS) by way of token exchange to get access to a resource. They'll log in to their Google account, for instance, and be granted access to your app.

Using SSO means that:

You don't have to manage passwords yourself! This reduces the user data you store and therefore less data to be exposed in the event of a data breach.
Not only do you avoid implementing login and logout, but you also avoid implementing multi-factor authentication.
Your users don't need a new account and new password—they've already got an account with an SSO provider like Google. Less friction at signup means more users for you.

OAuth2 is a standard that describes how a third-party application can access data from an application on behalf of a user. OAuth2 doesn’t directly handle authentication and is a more general framework built primarily for authorization . For example, a user might grant an application access to view their calendar in order to schedule a meeting for you. This would involve an OAuth2 interaction between the user, their calendar provider, and the scheduling application.

In the above example, OAuth2 is providing the mechanism to coordinate between the three parties. The scheduling application wants to get an access token so that it can fetch the calendar data from the provider. It obtains this by sending the user to the calendar provider at a specific URL with the request parameters encoded. The calendar provider asks the user to consent to this access, then redirects the user back to the scheduling application with an authorization code. This code can be exchanged for an access token Here's a good article on the details of OAuth token exchange ..

You can implement authentication on top of OAuth2 by fetching information that uniquely identifies the user, like an email address.

However, you should prefer to use OpenID Connect. The OpenID Connect specification is built on top of OAuth2 and provides a protocol for authenticating your users. Here's a getting started guide on OAuth2 with OpenID Connect .

Unfortunately, not every identity provider supports OpenID Connect. GitHub, for instance, won't let you use OpenID Connect. In that case, you'll have to deal with OAuth2 yourself. But good news—there's an OAuth2 library for your programming language of choice and plenty of good documentation!

Tips for OAuth

You can use OAuth2 in either stateless or stateful modes. Here’s a good summary on the differences .

The short version: it is typically easier to correctly implement a stateful backend to handle OAuth flows, since you can handle more of the sensitive data on the server and avoid the risk of leaking credentials. However, REST APIs are meant to be stateless. So if you want to keep the backend this way, you either need to use a stateless approach or add an additional stateful server to handle authentication.

If you opt to implement the stateless approach, make sure to use its Proof Key for Code Exchange mode, which prevents cross-site request forgery and code injection attacks.

You'll need to store users' OAuth credentials. Don't put them in local storage—that can be accessed by any JavaScript running on the page! Instead, store tokens as secure cookies. That will protect against cross-site scripting (XSS) attacks. However, cookies can be vulnerable to cross-site request forgery (CSRF), so you should make sure your cookies use SameSite =Strict.

Use API keys to give existing users programmatic access

While your REST endpoints can serve your own website, a big advantage of REST is that it provides a standard way for other programs to interact with your service. To keep things simple, don't make your users do OAuth2 locally or make them provide a username/password combo—that would defeat the point of having used OAuth2 for authentication in the first place. Instead, keep things simple for yourself and your users, and issue API keys. Here's how:

When a user signs up for access to your API, generate an API key: var token = crypto.randomBytes(32).toString('hex');
Store this in your database, associated with your user.
Carefully share this with your user, making sure to keep it as hidden as possible. You might want to show it only once before regenerating it, for instance.
Have your users provide their API keys as a header, like curl -H "Authorization: apikey MY_APP_API_KEY" https://myapp.example.com
To authenticate a user's API request, look up their API key in the database.

When a user generates an API key, let them give that key a label or name for their own records. Make it possible to later delete or regenerate those keys, so your user can recover from compromised credentials.

Encourage using good secrets management for API keys

It's the user's responsibility to keep their secrets safe, but you can also help! Encourage your users to follow best practices by writing good sample code. When showing API examples, show your examples using environment variables, like ENV["MY_APP_API_KEY"].

(If you, like Stripe, write interactive tutorials that include someone's API key, make sure it's a key to a test environment and never their key to production.)

Choose when to enforce authorization with request-level authorization

We've been speaking about API authorization as if it will apply to every request, but it doesn't necessarily need to. You might want to add request-level authorization : looking at an incoming request to decide if the user has access to your resources or not. That way, you can let everyone see resources in /public/, or choose certain kinds of requests that a user needs to be authenticated to make.

The best way to do this is with request middleware. Kelvin Nguyen over at Caffeine Coding has a nice example here .

Configure different permissions for different API keys

You'll give users programmatic API access for many different reasons. Some API endpoints might be for script access, some intended for dashboards, and so on. Not every endpoint will need the user's full account access. Consider having several API keys with different permission levels.

To do this, store permissions in the database alongside the API keys as a list of strings. Keep this simple at first: "read" and "write" are a great start! Then, add a request middleware that fetches the user and the permissions for the key they've submitted and checks the token permissions against the API.

Leave the rest of the authorization to the app/business logic

Now that you've started adding authorization to your API, it can be tempting to add more and more logic to handle more checks. You may end up with nested if-statements for each resource and permission level. The problem with that is that you may end up duplicating application logic. You'll find yourself fetching database records in the middleware, which is not ideal!

Instead, leave that level of authorization logic to your application code. Any authorization checks made on resources should happen in the app, not in the middleware. If you need to handle complex authorization logic in your app, use a tool like Oso , which will let you reduce your authorization policy to a few simple rules.

There's always more to discuss with authentication and authorization, but that's enough to get started! We hope these tips help you design useful and secure API endpoints.

In summary: use good libraries

We’ve given you plenty of specific advice, but it all comes back to one point—try to offload as much work as you can to trusted libraries. Authorization is tricky, and we’d like to minimize the number of places in which we can make a mistake. You have plenty of great tools at hand to help with authorization, so make the best use of them that you can! Much like with cryptography: study up, and then do as little as possible yourself.

ASP.NET Core

Preventing mass assignment or over posting in ASP.NET Core

Mass assignment, also known as over-posting, is an attack used on websites that involve some sort of model-binding to a request. It is used to set values on the server that a developer did not expect to be set. This is a well known attack now, and has been discussed many times before , (it was a famous attack used against GitHub some years ago ), but I wanted to go over some of the ways to prevent falling victim to it in your ASP.NET Core applications.

How does it work?

Mass assignment typically occurs during model binding as part of MVC. A simple example would be where you have a form on your website in which you are editing some data. You also have some properties on your model which are not editable as part of the form, but instead are used to control the display of the form, or may not be used at all.

For example, consider this simple model:

It has two properties, but we only actually going to allow the user to edit the Name property - the IsAdmin property is just used to control the markup they see:

So the idea here is that you only render a single input tag to the markup, but you post this to a method that uses the same model as you used for rendering:

This might seem OK - in the normal browser flow, a user can only edit the Name field. When they submit the form, only the Name field will be sent to the server. When model binding occurs on the model parameter, the IsAdmin field will be unset, and the Name will have the correct value:

However, with a simple bit of HTML manipulation, or by using Postman/Fiddler , a malicious user can set the IsAdmin field to true . The model binder will dutifully bind the value, and you have just fallen victim to mass assignment/over posting:

Defending against the attack

So how can you prevent this attack? Luckily there's a whole host of different ways, and they are generally the same as the approaches you could use in the previous version of ASP.NET. I'll run through a number of your options here.

1. Use BindAttribute on the action method

Seeing as the vulnerability is due to model binding, our first option is to use the BindAttribute :

The BindAttribute lets you whitelist only those properties which should be bound from the incoming request. In our case, we have specified just Name , so even if a user provides a value for IsAdmin , it will not be bound. This approach works, but is not particularly elegant, as it requires you specify all the properties that you want to bind.

2. Use [Editable] or [BindNever] on the model

Instead of applying binding directives in the action method, you could use DataAnnotations on the model instead. DataAnnotations are often used to provide additional metadata on a model for both generating appropriate markup and for validation.

For example, our UserModel might actually be already decorated with some data annotations for the Name property:

Notice that as well as the Name attributes, I have also added an EditableAttribute . This will be respected by the model binder when the post is made, so an attempt to post to IsAdmin will be ignored.

The problem with this one is that although applying the EditableAttribute to the IsAdmin produces the correct output, it may not be semantically correct in general. What if you can edit the IsAdmin property in some cases? Things can just get a little messy sometimes.

As pointed out by Hamid in the comments, the [BindNever] attribute is a better fit here. Using [BindNever] in place of [Editable(false)] will prevent binding without additional implications.

3. Use two different models

Instead of trying to retrofit safety to our models, often the better approach is conceptually a more simple one. That is to say that our binding/input model contains different data to our view/output model. Yes, they both have a Name property, but they are encapsulating different parts of the system so it could be argued they should be two different classes:

Here our BindingModel is the model actually provided to the action method during model binding, while the UserModel is the model used by the View during HTML generation:

Even if the IsAdmin property is posted, it will not be bound as there is no IsAdmin property on BindingModel . The obvious disadvantage to this simplistic approach is the duplication this brings, especially when it comes to the data annotations used for validation and input generation. Any time you need to, for example, update the max string length, you need to remember to do it in two different places.

This brings us on to a variant of this approach:

4. Use a base class

Where you have common properties like this, an obvious choice would be to make one of the models inherit from the other, like so:

This approach keeps your models safe from mass assignment attacks by using different models for model binding and for View generation. But compared to the previous approach, you keep your validation logic DRY .

There is also a variation of this approach which keeps your models completely separate, but allows you to avoid duplicating all your data annotation attributes by using the ModelMetadataTypeAttribute .

5. Use ModelMetadataTypeAttribute

The purpose of this attribute is to allow you defer all the data annotations and additional metadata about you model to a different class. If you want to keep your BindingModel and UserModel hierarchically distinct, but also son't want to duplicate all the [MaxLength(200)] attributes etc, you can use this approach:

Note that only the UserModel contains any metadata attributes, and that there is no class hierarchy between the models. However the MVC model binder will use the metadata of the equivalent properties in the UserModel when binding or validating the BindingModel .

The main thing to be aware of here is that there is an implicit contract between the two models now - if you were to rename Name on the UserModel , the BindingModel would no longer have a matching contract. There wouldn't be an error, but the validation attributes would no longer be applied to BindingModel .

This was a very quick run down of some of the options available to you to prevent mass assignment. Which approach you take is up to you, though I would definitely suggest using one of the latter 2-model approaches. There are other options too, such as doing explicit binding via TryUpdateModelAsync<> but the options I've shown represent some of the most common approaches. Whatever you do, don't just blindly bind your view models if you have properties that should not be edited by a user, or you could be in for a nasty surprise.

And whatever you do, don't bind directly to your EntityFramework models. Pretty please.

Use Project schedule APIs to perform operations with Scheduling entities

10 contributors

Applies To: Project Operations for resource/non-stocked based scenarios, Lite deployment - deal to proforma invoicing.

Scheduling entities

Project schedule APIs provide the ability to perform create, update, and delete operations with Scheduling entities . These entities are managed through the Scheduling engine in Project for the web. Create, update, and delete operations with Scheduling entities were restricted in earlier Dynamics 365 Project Operations releases.

The following table provides a full list of the Project schedule entities.

OperationSet

OperationSet is a unit-of-work pattern that can be used when several schedule impacting requests must be processed within a transaction.

Project schedule APIs

The following is a list of current Project schedule APIs.

Using Project schedule APIs with OperationSet

Because records are created immediately for both CreateProjectV1 and CreateTeamMemberV1 , these APIs can't be used directly in the OperationSet . However, you can use them to create the required records, create an OperationSet , and then use the pre-created records in the OperationSet .

Supported operations

* Resource assignment records aren't updated. Instead, the old record can be deleted, and a new record can be created. A separate API has been provided to update Resource Assignment contours.

The ID property is optional. If it's provided, the system tries to use it and throws an exception if it can't be used. If it isn't provided, the system generates it.

Limitations and known issues

The following is a list of limitations and known issues:

Project Schedule APIs can only be used by Users with Microsoft Project License . They can't be used by:

Application users
System users
Integration users
Other users that don't have the required license

Each OperationSet can only have a maximum of 200 operations.

Each user can only have a maximum of 10 open OperationSets .

Project Operations currently supports a maximum of 500 total tasks on a project.

Each Update Resource Assignment Contour operation counts as a single operation.

Each list of updated contours can contain a maximum of 100 time slices.

OperationSet failure status and failure logs aren't currently available.

There's a maximum of 400 sprints per project.

Limits and boundaries on projects and tasks .

Labels are currently only available for Project for the Web.

Labels are created the first time you open a project.

There's a maximum of 10 goals per project.

Each task can appear in Project Task to Goal once.

Error handling

To review errors generated from the Operation Sets, go to Settings > Schedule Integration > Operations Sets .
To review errors generated from the Project schedule Service, go to Settings > Schedule Integration > PSS Error Logs .

Editing Resource Assignment Contours

Unlike all other project scheduling APIs that update an entity, the resource assignment contour API is solely responsible for updates to a single field, msdyn_plannedwork, on a single entity, msydn_resourceassignment.

Given schedule mode is:

fixed units .
The project calendar is from 9:00 to 5:00 PM (Pacific Time) Monday, Tuesday, Thursday, and Friday. ( There's no work on Wednesdays. )
The resource calendar is from 9:00 AM to 1:00 PM (Pacific Time) Monday through Friday.

This assignment is for one week, four hours a day. This is because the resource calendar is from 9:00 AM to 1:00 PM (Pacific Time), or four hours a day.

For example, if you want the worker to only work three hours each day this week and allow for one hour for other tasks.

UpdatedContours sample payload

This is the assignment after the Update Contour Schedule API is run.

Sample scenario

In this scenario, you create a project, a team member, four tasks, and two resource assignments. Next, you update one task, update the project, update a resource assignment contour, delete one task, delete one resource assignment, and create a task dependency.

Additional samples

Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. For more information see: https://aka.ms/ContentUserFeedback .
