Issue
I need to store uploaded files to Firebase storage and save their link with the corresponding user document in Firestore. However, since there is no native integration between them, I need to use the REST API interface to connect both services together.
Resolution
As there is no native integration between Firebase and Appsmith, we have a feature request open for this. Please feel free to watch or subscribe to it for updates.
Meanwhile, you can follow the tutorial available in the official Firebase documentation to connect using Firestore and then use Appsmith to interact with Firestore. For more information on Firestore datasource, see the Firestore reference guide.
