This document explains how you can manage your app's Firebase Realtime Database Security Rules through the REST API.
Updating Firebase Realtime Database Security Rules
Using the REST API, you can write and update
Firebase Realtime Database Security Rules for your
Firebase app by making a PUT request to the /.settings/rules.json path.
To do this, we'll need an access token to authenticate our REST request
In this example, we enable read access for all data in our Firebase database:
curl -X PUT -d '{ "rules": { ".read": true } }' 'https://docs-examples.firebaseio.com/.settings/rules.json?access_token=<ACCESS_TOKEN>'
Retrieving Firebase Realtime Database Security Rules
Similarly, we can make a GET request to the /.settings/rules.json path of our app's
URL to retrieve our Firebase Realtime Database Security Rules:
curl 'https://docs-examples.firebaseio.com/.settings/rules.json?access_token=<ACCESS_TOKEN>'
The response will contain all of the rules for our app.
