Webapp website and webapp API authentication

Hi Walter, Welcome to MS Q&A

To enable authorized access for communication between a website and web API using Azure App Service, you need to enable authentication and authorization for both the website and the web API. This involves creating an app registration in your workforce or external tenant, granting the frontend app access to the backend app, configuring App Service to return a usable token, and using the token in your code. You can follow the steps outlined in the Azure App Service documentation to enable authentication and authorization for your website and web API.

Here are the general steps to enable authorized access for communication between a website and web API using Azure App Service:

1. Create an app registration in your workforce or external tenant.
2. Enable authentication and authorization for both the website and the web API.
3. Grant the frontend app access to the backend app on the user's behalf.
4. Configure App Service to return a usable token.
5. Use the token in your code.

You can find detailed instructions on how to perform these steps in the following Microsoft documentation:
