What is a reply URL (redirect URI)?
A reply URL, also known as a redirect URI, is the location where users are redirected after they have successfully authenticated with Azure AD. The URL is essential because it ensures a secure flow of tokens between your application and Azure AD.
How do I find the correct reply URL for my application?
The correct reply URL depends on the type of application and its configuration. Generally, the reply URL should point to a location in your application where authentication tokens can be processed and user sessions can be established. Check your application's documentation for specific guidance on determining the correct reply URL.
Can I have multiple reply URLs for my application?
Yes, you can add multiple reply URLs for your application in the Azure AD app registration settings. This can be useful if your application has different environments (e.g., development, staging, and production) or supports multiple authentication flows.
Why am I still getting the AADSTS500113 error after adding a reply URL?
Ensure that you have entered the correct reply URL and that it matches the expected format for your application type. If you still encounter issues, double-check your application's configuration and ensure it is correctly set up to handle authentication tokens from Azure AD.
Can I use a wildcard in the reply URL?
No, using a wildcard in the reply URL is not recommended because it can expose your application to security risks. Instead, specify the exact reply URLs for your application to ensure a secure flow of tokens between your application and Azure AD.
