Headers
OAuth2 authentication flows. Auth server URLs will vary by environment
API key for authentication
API version to use (optional, defaults to latest). Supported values: 1.0.0, 1.1.0.
Client-generated unique key (UUID/ULID recommended). JSON requests: the first 2xx response is cached for 24h and replayed on a same-key retry with a matching body; a different body returns 422. Non-JSON requests (e.g. file uploads): the key is single-use — any same-key retry returns 422 regardless of body. See Idempotency for full details.
