Creating ICMs via Activator

HI iremugurlu ,

Fabric Activator usually calls downstream services using a Microsoft managed backend identity, so you normally do not need to create your own service principal. For the ICM connector type, you can try using Managed Certificate first since many Microsoft services use that model for service to service calls. If the test action fails, check the ICM connector logs or error message. Sometimes the failure response shows the caller application id that attempted the request. You can take that application id and add it to the allowed callers list in the ICM connector configuration and try again. For routing id and connector id, these are usually created and managed by your organization’s ICM admin or owning team, so you will need to use the values defined in your internal routing setup. This approach may help identify the correct caller identity and resolve the authorization issue.
