Connect Google Firestore

  3. Fill in the fields. Secret values are encrypted and never shown again.
  4. Click Test, then Create Connection.
If the system is only reachable inside your network, choose an On-Prem Worker under Test from and run the flow on that Worker. See On-Prem Workers.

Use it in a flow

  1. Open a flow, open the node library and search for Google Firestore.
  2. Drag it onto the canvas and choose an Operation and your connection.
  3. Map the operation's fields from earlier steps, or click Map with Matt.
  4. Use Test this step to see what it returns, then save.

To start a flow from Google Firestore without a ready-made trigger: a Poll for changes trigger can check one of its list operations on a schedule and pass on only what is new; if Google Firestore can send webhooks, a Webhook trigger receives them at its own URL.
