I am trying to set up a webhook integration with Firebase and I am having problems doing the authentication bit correctly.
Some tutorials are showing using Legacy tokens, that Firebase recommends not using now.
I would like to authenticate using user/password, but I cannot figure it out why even putting those values on the webhook, I get authentication denied.
Oh, yea, it is possible to write to Firebase using the Google Cloud Integration, which supports non-legacy authentication. Caveat is that you need to use either an App Engine instance or Google Cloud Function. On the plus side, you can manipulate the data before it goes into the database so you have much better control over what goes into the fields.
