Use this file to discover all available pages before exploring further.

This reference is generated from our OpenAPI 3.1 specification, so it always matches the live API. Each endpoint below has its own page with parameters, request bodies, response schemas, and a request playground.

​
Conventions

  • Base URL: https://formitto.com/v1
  • Auth: Authorization: Bearer fmt_live_... (see Authentication)
  • Lists return { data, pagination }; single resources return the object directly.
  • Pagination: page (1-based) and limit (default 25, max 100).
  • Rate limits: 1000 requests/hour per key; read X-RateLimit-* headers, back off on 429.

​
Errors

Every error uses a consistent shape with a stable machine-readable code: 
{ "error": "Human-readable message", "code": "stable_code" }
Common codes: invalid_api_key (401), insufficient_scope (403), not_found (404), rate_limited (429), plus request-specific codes like domain_required and forbidden_field (400). Browse the endpoints in the sidebar, or start with the getting-started guide.
