Attio CRM API

A developer-first REST API for building high-scale, data-driven workflows on Attio's flexible CRM engine.

Attio provides a high-performance REST API designed for deep integration and data synchronization. Developers use it to push data from sources like Stripe or Segment into custom objects and attributes. The system supports standard HTTP methods (GET, POST, PATCH) and secures connections via OAuth 2.0. You can programmatically manage records, lists, and notes to automate sales cycles at scale. Rate limits are generous (starting at 1,000 requests per minute) to keep your production workflows running smoothly.
