GCP Credentials

Since the GCP Firestore component uses the GCP Go Client Libraries, by default it authenticates using Application Default Credentials. This is explained in the Authenticate to GCP Cloud services using client libraries guide.

Setup GCP Firestore

You can use the GCP Datastore emulator to run locally using the instructions here.

You can then interact with the server using http://localhost:8432.
