Issues with Calling Bridge API in Appian via SAML and Azure

Hello everyone,

In our Appian setup, we are utilizing SAML within Azure to embed Appian interfaces into an Azure application. We've encountered some issues when attempting to call the Microsoft Graph API, so we decided to create a Bridge API in our Azure application and make calls to it directly using the existing browser token connection.

When I log into the application using SAML and then open a new browser window to call our Bridge API, I receive the expected data. However, when using a!httpWrite for a POST request to retrieve the API information, the response only returns an HTTP 200 confirmation code without any actual data.

I assumed that no additional authentication methods would be necessary since I'm already connected to the application. Has anyone faced a similar issue or can you suggest anything I might have overlooked?

Thanks for your help!
