I am unable to add my new FCM v1 credentials to the azure notification hub, it responds with Invalid Firebase Credentials

Mark Zacharias 5

I have an existing notification hub that has been using the legacy FCM server key. I'm trying to update it to use the newer FCM v1 credentials. I've created the correct service account and enabled Firebase Cloud Messaging API (V1) in the google console. I've tested those credentials in a simple app however, when I try to enter them into the azure notification portal it fails.

{"error":{"code":"BadRequest","message":"Invalid Firebase credentials."}}

Mark Zacharias, Apologies for the delayed response.

I understand that you have tested those credentials/app. If you haven't done, please ensure that you have enabled the FCM V1 in the Cloud Messaging tab in Firebase. This step is often overlooked and can cause the "Invalid Firebase Credentials" error ( similar discussion thread)

Double-check that the service account JSON file you are using contains the correct clientEmail, projectId, and privateKey values. These should be directly copied from the JSON file provided by Google.
Ref: Ensure that FCM credentials are updated. Follow step 1 in the REST API guide.

Do I need to store both FCM legacy and FCM v1 credentials?

Yes, FCM legacy and FCM v1 are treated as two separate platforms in Azure Notification Hubs, so you must store both FCM legacy and FCM v1 credentials separately. For more information, see the instructions to set up credentials.

Kindly let us know, I'll follow-up with you further.
