RTDB & Message

[arielba]

I'm trying to write to RTDB and send message in the same sketch, but I can't complete both tasks. And I'm lost.
On the line:
initializeApp(client1, app, getAuth(dbSecret), getAuth(sa_auth), aResult_no_callback);
to write to RTDB getAuth authenticates with dbSecret, and to send message with sa_auth. How should I authenticate both?
I would like you to give me a hand. Thank you in advance

You have to use ServiceAuth that can be used for FCM and RTDB.

FirebaseClient/examples/Messaging/Async/Callback/Send/Send.ino

Lines 59 to 60 in 2368fed

	// ServiceAuth is required for Cloud Messaging.
	ServiceAuth sa_auth(timeStatusCB, FIREBASE_CLIENT_EMAIL, FIREBASE_PROJECT_ID, PRIVATE_KEY, 3000 /* expire period in seconds (<= 3600) */);

@arielba, can you provide final example?
