Error when connect Azure AI Search to Copilot Studio

Question

I'm able to add a connection of azure ai search to copilot studio, but I got the message "Access deined".
Im able to call the Search API via Postman.
How to fix it. Thank you all!

Answer 1

The “Access denied” message in Copilot Studio when connecting to Azure AI Search, despite successful API calls in Postman, usually means:

• The credentials or authentication method used in Copilot Studio do not have the required permissions on the Azure AI Search resource.
• The connection in Copilot Studio may be using a different identity (service principal, managed identity, or user account) than Postman.

How to resolve:

1. Check the authentication method in Copilot Studio:
   • Ensure you are using the same API key or Azure AD identity as in Postman.
   • If using Azure AD, confirm the user/service principal has the correct role (e.g., Search Service Contributor) on the Azure AI Search resource.
2. Verify permissions in Azure Portal:
   • Go to your Azure AI Search resource → Access control (IAM).
   • Add the required role to the identity used by Copilot Studio.
3. Check connection configuration:
   • Double-check the endpoint, API key, or client ID/secret in Copilot Studio.
4. Try re-authenticating or reconnecting:
   • Remove and re-add the connection in Copilot Studio.
