Authentication#

Firebase Admin uses API keys for authentication. When you connect your Firebase Admin account, Pipedream securely stores the keys so you can easily authenticate to Firebase Admin APIs in both code and no-code steps.

Enable the Cloud Firestore API on your Firebase account, and make sure you've created at least one collection in the database.
Follow these instructions to generate a private key tied to your Firebase service account. This will generate a JSON file that contains the project ID, private key, and client email that you should paste below.
When entering the private key, please add the full string included in the JSON file, from -----BEGIN PRIVATE KEY----- to -----END PRIVATE KEY-----, with all newline characters included.
