Firebase Databases # Connect Firebase to Hypamoon Yes, with one catch. Firebase has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of Firebase, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://firebase.google.com/docs/firestore/use-rest-api) **A key you create yourself**\ **Yes.** Create a service account in your own Google Cloud project and use it to get an OAuth 2.0 token; no review needed. [firebase.google.com](https://firebase.google.com/docs/firestore/use-rest-api) **Versions or a changelog**\ **Yes.** Versioned REST paths (Firestore v1) and public release notes. [firebase.google.com](https://firebase.google.com/support/releases) **How it signs in**\ Google OAuth 2.0 access token from a service account key for server use; Firebase ID tokens for requests on behalf of app users. The Realtime Database still accepts legacy database secrets. **Webhooks**\ **No.** [firebase.google.com](https://firebase.google.com/docs/functions/firestore-events) **Hosting**\ Cloud ## What you can build Look up and update documents in Firestore from your chat, for example orders or bookings your app stores. Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Firebase signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Firebase takes more work: ask your chat to check this first. - Firebase has no outgoing webhooks; to react to changes you write a Cloud Function on a Firestore trigger. Requests with a service account skip Security Rules and use IAM instead. ## Try it in your chat Fill in what to read and write, and send it.
