x-generated: '2026-08-13'
x-method: generated
x-source: derived from authentication/postmark-authentication.yml, errors/postmark-problem-types.yml and
  conventions/postmark-conventions.yml against openapi/postmark-triggers-api-openapi.yml
x-note: 'Non-destructive. The underlying OpenAPI is never mutated. Every action below adds something Postmark
  documents on postmarkapp.com but does not express in the machine-readable contract: the two authentication
  schemes, the https scheme on the server URL (the harvested spec carries a protocol-relative "//api.postmarkapp.com/"),
  contact/licence metadata, and the six documented HTTP error statuses missing from every operation.'

  description: Pin the production server to an absolute https URL. Postmark enforces TLS and stopped accepting
    plain HTTP on 2022-09-01; the harvested spec carries a scheme-relative server URL that is not a valid
    absolute URL.

  description: Declare the two API token schemes. Every Postmark spec in this repo ships with no securitySchemes
    at all, so a generator reading the spec alone emits an unauthenticated client.
  update:
    securitySchemes:
      serverToken:
        type: apiKey
        in: header
        name: X-Postmark-Server-Token
        description: Server-level API token. Send POSTMARK_API_TEST to validate a request without delivering
          mail.
      accountToken:
        type: apiKey
        in: header
        name: X-Postmark-Account-Token
        description: Account-level API token, required by Servers, Domains, Sender Signatures and Data
          Removal.
- target: $.paths.*.*.responses
  description: Add the documented HTTP statuses absent from every operation. The specs declare only 200,
    422 and 500; Postmark also documents 401, 404, 413, 415, 429 and 503.
  update:
    '401':
      description: Unauthorized — missing or incorrect API token in header.
    '404':
      description: Entity doesn't exist — the requested resource or ID was not found.
    '413':
      description: Payload Too Large — over 10 MB (Email API) or 50 MB (Batch/Bulk).
    '415':
      description: Unsupported Media Type — Accept and Content-Type must be application/json.
    '429':
      description: Rate Limit Exceeded — reduce request rate. No RateLimit-* or Retry-After header is
        returned.
    '503':
      description: Service Unavailable — planned maintenance window.
- target: $
  description: Record cross-cutting runtime semantics captured in conventions/postmark-conventions.yml.

    x-idempotency:

      note: Postmark publishes no idempotency key. A retried send is a second send.
