Since I want to send a firebase push notiffication with FCM token, the http request requires both the FCM token and an auth token from google, how do I implement this?
@Punosie
use the OAuth2 API credential.
here is the setup i use for fcm v1:
Go to Firebase Console → Project Settings → Service Accounts → Generate New Private Key
Service Account (this is important).https://oauth2.googleapis.com/tokenhttps://www.googleapis.com/auth/firebase.messaging (this is what allows push notifications).in The HTTP Request Node:
https://fcm.googleapis.com/v1/projects/YOUR_PROJECT_ID/messages:sendmy bad. i totally sent you down the wrong path.
n8n changed how these are grouped. the generic “OAuth2 API” doesn’t have the service account dropdown anymore.
you need to search the credentials list for Google Service Account instead.
it’s actually way easier now:
Email and Private Key directly into it.https://www.googleapis.com/auth/firebase.messaging scope into the new box that pops up.select that new credential in your http node and it’ll handle the token rotation properly.
what all permissions do I need to give to the service account then ?
in the google cloud console (IAM & Admin section), you need to assign your service account the Firebase Cloud Messaging API Admin role,make sure you select exactly that one.
this video walks through the exact steps of navigating the google console for FCM v1 if you want a visual on where to assign those specific permissions.
Thanks a lot
it is already in here , happy that i could help you!
