Our full API documentation lives on our developer docs site, where it stays up to date with every release.
Whether you're calling the API directly or connecting an AI agent through MCP, our developer docs cover everything you need: authentication with scoped API keys, endpoints, request and response examples, error handling, and step-by-step guides to get your first call working.
Read the official API docs (https://api.getsequence.io/platform/)
Already using the legacy API? It's not deprecated and your existing keys still work, so nothing changes on your end. The Platform API is the newer path, and whenever you're ready the docs walk you through it.
If you run into trouble or have a question the docs don't answer, reach out to our team and we'll help you get unblocked.
