Trouble Authenticating with a Third-Party API Using Managed Identity in Azure Logic Apps
I'm prototyping a solution and After trying multiple solutions online, I still can't figure this out. After trying multiple solutions online, I still can't figure this out. I'm relatively new to this, so bear with me. Building a solution that integrates several third-party APIs using Azure Logic Apps, I've hit a snag while trying to authenticate with one of them using Managed Identity. The Logic App is supposed to fetch user data from an API that requires OAuth 2.0 token-based authentication. In my current setup, I've configured the Logic App with a Managed Identity, and I have registered this identity in Azure Active Directory. I've also assigned the necessary API permissions. Here’s how I set it up: ```json { "auth": { "clientId": "<client-id>", "clientSecret": "<client-secret>", "tenantId": "<tenant-id>", "resource": "<api-resource-url>" } } ``` When I run the Logic App, it triggers successfully, but the HTTP action fails with a 401 Unauthorized error. The API documentation specifies that the access token should be included in the Authorization header as follows: ```http Authorization: Bearer <access-token> ``` I have tried using the HTTP connector's built-in authentication options, and I’ve also tested the token acquisition using Postman, which works fine. The flow continues to break even with the retry policy implemented. Additionally, I’ve been experimenting with adding an HTTP action before the GET operation to explicitly call the token endpoint, but that hasn’t resolved the issue either. I suspect it might be a scope issue with the permissions granted to the Managed Identity, but I can’t pinpoint what might be missing. Can anyone share insights on best practices for setting up Managed Identity with Logic Apps, or point out what I might have overlooked in the configuration? My development environment is Windows. Thanks in advance! What am I doing wrong? I'd be grateful for any help. Am I approaching this the right way?
