Hi @helenabsj8
Good question.
Most apps on Zapier are built and maintained by the app developers themselves, Zapier keeps an internal list of app requests.

Hi @helenabsj8!
The Firebase integration is one that Zapier built and maintains, which means that we are responsible for updating it, adding any feature requests, etc. There is an open feature request to be able to update Firestore documents in I've added your email address as another vote for this addition. I don't have an ETA of when or if this will happen, but we will definitely email you if it does become a reality.
Thanks!
