Linkify API Documentation

Secure links with powerful analytics. Build, scale, and monitor your shortening infrastructure with our RESTful API.

Introduction to the Linkify API

The Linkify API is a high-performance, rate-limited REST interface designed for developers who need predictable link generation, real-time click tracking, and webhook-driven event streaming. Base endpoint: `https://api.linkify.io/v2`. All requests require HTTPS and return JSON payloads with standard HTTP status codes.

Our infrastructure processes over 4.2 million requests daily with a 99.98% uptime SLA. Rate limits are enforced per API key, starting at 1,200 requests per minute for free tiers and scaling to 15,000 RPM on Enterprise plans. Error responses include detailed diagnostic codes like `LINK_ALREADY_EXISTS` or `QUOTA_EXCEEDED` to simplify debugging.
