We can use any Firebase Realtime Database URL as a REST endpoint. All we need
to do is append
.json to the end of the URL and send a request from
our favorite HTTPS client.
Create an Account
First sign up for an account at no cost in the Firebase console. A new
Firebase app will be created for you with a unique URL ending in
firebaseio.com. You'll use this URL to authenticate your users and
to store and sync data to the app's database.
Within the Firebase console you can create, manage and delete Firebase apps. Clicking on a specific Firebase app lets you view and modify your app's database in real time. In your app dashboard, you can also set Firebase Realtime Database Security Rules, manage your app's authentication, deploys, and view analytics.
Create a Database
Navigate to the Realtime Database section of the Firebase console. You'll be prompted to select an existing Firebase project. Follow the database creation workflow.
Select a starting mode for your Firebase Security Rules:
- Test mode
Good for getting started with the mobile and web client libraries, but allows anyone to read and overwrite your data. After testing, make sure to review the Understand Firebase Realtime Database Rules section.
To get started with the web, Apple, or Android SDK, select testmode.
- Locked mode
Denies all reads and writes from mobile and web clients. Your authenticated application servers can still access your database.
Choose a location for the database.
Depending on the location of the database, the URL for the new database will be in one of the following forms:
(for databases in
(for databases in all other locations)
When you enable Realtime Database, it also enables the API in the Cloud API Manager.
Choose a Helper Library
You can read and write data through the REST API directly from the command line. In this guide we'll use cURL for all of our examples. We also have several third-party helper libraries for interacting with the REST API from your favorite language. You can use one of the following helper libraries or create your own:
