Overview

Firebase Auth API is a authentication & identity apis provided by Firebase. Authentication with email, phone, Google, and social providers for mobile and web. This API is designed to help developers integrate auth capabilities into their applications with minimal setup and maximum reliability.

The API supports OAuth 2.0 authentication, ensuring secure access to all endpoints. With a freemium pricing model, Firebase offers flexible options for projects of any size, from prototypes to enterprise deployments.

Firebase maintains comprehensive documentation, SDKs for popular programming languages, and active community support. The API is built on REST principles, returning JSON responses with standard HTTP status codes, making it straightforward to integrate into existing workflows.

Authentication

This API uses OAuth 2.0 authentication. Exchange your client credentials for an access token, then send the token as a Bearer token in the Authorization header.

Always store your credentials securely using environment variables or a secrets manager. Never commit API keys to version control or expose them in client-side code.

Code Samples

Python

import requests
import os

API_KEY = os.environ.get("API_KEY", "YOUR_API_KEY")
BASE_URL = "https://api.firebase.google.com"

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

response = requests.get(f"{BASE_URL}/v1/resources", headers=headers)
print(response.status_code)
print(response.json())

JavaScript

const API_KEY = process.env.API_KEY || 'YOUR_API_KEY';
const BASE_URL = 'https://api.firebase.google.com';

const response = await fetch(`${BASE_URL}/v1/resources`, {
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  }
});
const data = await response.json();
console.log(data);

    req, _ := http.NewRequest("GET", "https://api.firebase.google.com/v1/resources", nil)
    req.Header.Set("Authorization", "Bearer " + apiKey)
    req.Header.Set("Content-Type", "application/json")
    resp, _ := http.DefaultClient.Do(req)
    defer resp.Body.Close()
    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))
}
