Overview

The Upwork API gives developers programmatic access to the Upwork freelance platform, including job listings, freelancer profiles, and contract management. It uses OAuth 2.0 for secure authentication, allowing your app to act on behalf of a user. It is suited for building tools that automate hiring workflows or integrate Upwork data into your own systems.

💡

Beginner Tip

Upwork uses OAuth 2.0, so you need to complete an authorization flow to get an access token before making any API calls—test with the sandbox environment first. Store your refresh token securely and implement token renewal to avoid session expiry errors.

JSON-formatted response data
Requires OAuth authentication

Implementation Example 

const url = "https://developers.upwork.com/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);
