Firestore Custom Tokens

Question

I am trying to use a custom auth token with firestore. I am using nodejs to generate the token with the following code.

const admin = require(\'firebase-admi

You can't directly access REST APIs with a custom token. You need to sign in using the custom token, and obtain an ID token. There are 2 ways to do this:

• Sign in from a Firebase Client SDK
• Use the Firebase Auth REST API to exchange the custom token to an ID token.

Then you can access the Firestore REST API with the resulting ID token:
