Bing Webmaster Tools API — How to Access Search Performance Data Programmatically

Bing Webmaster Tools provides a full-featured API that lets you access search performance data (impressions, clicks, rankings, and more) programmatically. This article covers the API basics and how to get started.

What You Can Do with the API

The Bing Webmaster Tools API gives programmatic access to the following data:

• Rank & Traffic Stats — Daily impressions and clicks
• Link Details — Inbound link information
• Keyword Details — Keyword-level rankings and traffic
• Crawl Stats — Crawl volume and errors
• URL & Sitemap Submission — Submit URLs and sitemaps to Bing

Authentication

Two authentication methods are available:

1. API Key (Quick Start)

Generate an API key from your Bing Webmaster Tools settings:

1. Sign in to Bing Webmaster Tools
2. Click Settings (top right) → API Access
3. Accept the terms and click Generate API Key

Each API key is user-scoped — one key works across all sites owned by the same user.

2. OAuth 2.0 (Recommended)

1. Register an OAuth client under Settings → API Access
2. Obtain a Client ID and Client Secret
3. Use the Authorization Code Flow to get an access token
4. Refresh tokens enable automatic renewal

Available scopes:

• webmaster.read — Read-only access
• webmaster.manage — Read and write access

Endpoints and Protocols

The API supports three protocols:

The JSON endpoint is the easiest to work with from modern applications.

Key API Methods

Usage Examples (Node.js)

API Key

const API_KEY = 'YOUR_API_KEY';
const SITE_URL = 'https://www.example.com/';

const res = await fetch(
  `https://ssl.bing.com/webmaster/api.svc/json/GetRankAndTrafficStats?apikey=${API_KEY}&siteUrl=${encodeURIComponent(SITE_URL)}`
);
const data = await res.json();
console.log(data);

OAuth 2.0

const res = await fetch(
  'https://ssl.bing.com/webmaster/api.svc/json/SubmitUrl',
  {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${ACCESS_TOKEN}`
    },
    body: JSON.stringify({
      siteUrl: 'https://www.example.com/',
      url: 'https://www.example.com/new-page'
    })
  }
);

Comparison with Google Search Console API

Conclusion

The Bing Webmaster Tools API provides a JSON endpoint that is easy to consume from Node.js and other modern runtimes. It offers two authentication paths — API Key for simplicity and OAuth 2.0 for production use. When combined with the Google Search Console API, you can build a unified search analytics pipeline covering both major search engines.
