7. After registration, you’ll be redirected to the application’s overview page, where you can access critical information such as the Application (client) ID, Directory (tenant) ID, and more.

Common FAQs about App Registration in Azure

1. What is the difference between single-tenant and multi-tenant applications?

A single-tenant application refers to an application that can only be accessed by users belonging to a specific Azure AD tenant. On the other hand, a multi-tenant application allows users from any Azure AD tenant to access the application. Developers must choose the appropriate tenant type based on their application’s requirements.

2. How can I define the permissions my application needs?

Azure provides the concept of “API permissions” to define the permissions required by your application. These permissions allow your application to access specific Azure resources or perform actions on behalf of the user. By specifying these permissions during App Registration, you can ensure your application is granted the necessary access.

3. How does single sign-on (SSO) work with Azure App Registration?

Azure App Registration simplifies the implementation of SSO. By integrating Azure AD with other identity providers, such as Active Directory Federation Services (AD FS), users can authenticate once and gain access to multiple applications without re-entering their credentials. Azure AD acts as the central repository for user identities, making SSO seamless across different applications.

4. How can I secure the communication between my registered application and Azure resources?

Azure App Registration supports the use of secure communication protocols such as OAuth 2.0 and OpenID Connect.

AADSTS900561 is an error code that indicates a specific issue encountered with the endpoint when it receives a GET request instead of the required POST request. In this article, we will explore the meaning and implications behind this error code, discuss why such errors occur, and provide potential solutions to resolve them.

To begin, let’s understand the context of AADSTS900561. AADSTS stands for Azure Active Directory Security Token Service, which is a component of Microsoft’s Azure platform responsible for issuing and validating security tokens. This service plays a vital role in ensuring secure authentication and authorization processes for various Azure applications and services.

Error code AADSTS900561 occurs when the endpoint, which is a specific URL or address where requests are sent, only accepts incoming POST requests but instead receives a GET request. These two request methods, GET and POST, are HTTP methods used to communicate with web servers. GET requests are used to retrieve data from a server, while POST requests are used to submit data to be processed by the server.

When the endpoint receives a GET request instead of a POST request, the server responds with the AADSTS900561 error code. This error message indicates a mismatch in the expected type of request and the received request, resulting in a failure to process the request and provide the intended response.

There can be various reasons why this error occurs. One common scenario is when developers or users mistakenly send GET requests rather than the required POST requests. This could be due to miscommunication or a misunderstanding of the API documentation or implementation details.

Another possible cause is when there are issues with the client application or the backend server. The client application may have a bug or an incorrect implementation, leading to erroneous request submissions. On the server side, there might be misconfigurations or limitations that only allow POST requests to access specific endpoints.

To troubleshoot and resolve the AADSTS900561 error, there are several steps you can take:

1. First, review the documentation or API specifications to ensure that you are sending the correct type of request. Double-check the required HTTP method (POST) for the specific endpoint you are trying to access.
