Freelancer API

Business / OAuth Advanced HTTPS
Varies by plan (check documentation)

Overview

The Freelancer API lets you post projects, search freelancers, and manage bids and contracts programmatically. It uses OAuth 2.0 and targets marketplace platform integrations.

Beginner Tip

OAuth setup requires registering an app on the Freelancer Developer Portal and completing a multi-step token flow — plan at least a day to get authentication working before touching project endpoints.

Available Data

Freelancer data via REST API

Example Response

JSON Response
{
  "status": "success",
  "data": {
    "result": "Data from Freelancer",
    "description": "Hire freelancers to get work done",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

result.projects List of project objects returned by the query.
result.projects[].id Unique numeric ID for the project.
result.projects[].title Human-readable title of the freelance project.
result.projects[].budget.minimum Minimum budget the client has set for the project in USD.
result.projects[].bid_stats.bid_count Number of bids submitted on this project so far.
result.status Top-level response status: "success" or an error descriptor.

Implementation Example

Request
const url = "https://developers.freelancer.com/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {

  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized Access token is missing, expired, or lacks required OAuth scopes
Re-authenticate to get a fresh token and ensure you requested the correct scopes (e.g. "basic", "jobs:read") when prompting the user.
403 Forbidden Your app does not have permission to perform this action on behalf of the user
Check that the user account used for testing has completed identity verification, and that you requested the correct OAuth scopes.
400 Bad Request with error_code field A required request parameter is missing or malformed
Read the error_code field in the response — Freelancer returns specific codes (e.g. "RequestDataError") with messages that pinpoint the bad field.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
