Our API documentation has always had examples for the most common endpoints, but if you wanted the full picture — every parameter, every response shape, every edge case — you had to piece it together yourself.
We now have an interactive API reference that lets you browse the complete OpenAPI specification. It covers every endpoint, with detailed request parameters, response schemas, and example payloads. You can expand and collapse sections, search across the spec, and download the raw OpenAPI file if you need it for tooling.
This is the same spec that powers the Mailcoach CLI — so what you see in the reference is always in sync with what the CLI and API actually support.
You’ll find the link in the API documentation sidebar.
