FireStore REST API call

Question

I am using postman to get data from my firestore api

https://firestore.googleapis.com/v1beta1/projects/myapp-ef511/databases/countries

but I am getting this,although my rules are public

{
    "error": {
        "code": 401,
        "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
        "status": "UNAUTHENTICATED"
    }
}

How can I achieve this?I am planning to use retrofit in future.

Go to Firebase console and follow the below steps.

Go to Project Settings (top left corner gear icon)
In General tab -> Under 'Your project' section it will show Project ID & Web API Key (will use it in url)
Now go to your Firestore database and get the document name e-g users

Finally just hit the below url with your desired values of Project ID, Web API Key and Document

https://firestore.googleapis.com/v1/projects/[Project ID]/databases/(default)/documents/[Document]?key=[Web API Key]

Example of real url:

https://firestore.googleapis.com/v1/projects/firestore-rest-api-test/databases/(default)/documents/players?key=AIzaSyDsCtB9PiFTtkJiDRmFEakbKvoohPRAGJU

NOTE: make sure you set your project rules on test mode to make it work. Otherwise use authentication first to make it work

What is test mode? Giving full read write access still returns 401 UNAUTHENTICATED – aalimovs Sep 29 '20 at 11:17
@aalimovs test mode is for testing purpose. For production you should do authentication and then call the API – Shujat Munawar Sep 29 '20 at 13:20
@SolutionSpirit how exactly do you enable test mode? I haven't had any luck using Web API Key to access the Firestore database at all, ended up using CLI with `gcloud auth application-default print-access-token` – aalimovs Sep 29 '20 at 14:14
It says permission denied! – Jamal Ud Din Feb 22 '22 at 06:29

The REST API requires either a Firebase Authentication ID token or Google Identity OAuth 2.0 token. The main difference between the two is that a Firebase Auth ID applies security rules and the Google ID does not. This guide on working with the Firestore REST API should help.

your rules maybe like this

    rules_version = '2';
service cloud.firestore {
 
 match /databases/{database}/documents {
 
   match /{document=**} {
 
     allow read, write: if
 
         request.time < timestamp.date(2021, 1, 15);
 
   }
 }
 
}

change to

    rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write;
    }
  }
}

this work for me
