  x-description: OpenAPI Overlay 1.0.0 capturing API Evangelist enrichments for this spec. It adds runtime
    semantics Snap documents in prose but does not express in the contract — rate limits, cursor pagination,
    partial-success responses, and the absence of idempotency. Apply it to the spec; never mutate the
    original.

  description: Every Marketing API operation shares one rate-limit envelope and one non-idempotent write
    posture. Snap publishes the numbers but no response headers, so record them on the operations where
    a client can act on them.
  update:
    x-rate-limit:
      application: 20 requests/second average across all tokens issued to the app
      token: 10 requests/second average per access token
      status: 429
      headers: []
      retry_after: false

    x-idempotency:
      supported: false
      note: No Idempotency-Key header. A retried write creates a duplicate entity.

  description: 'Snap documents cursor pagination for collection reads: a limit between 50 and 1000, and
    an absolute paging.next_link carrying an opaque cursor, ordered by CreatedAt.'

  description: The Marketing API can return HTTP 200 with failing entities inside. Warn consumers that
    the status line is not the outcome.
  update:
    x-partial-success:
      possible: true
      inspect: sub_request_status
      envelope:
      - request_status
      - request_id
      - sub_request_status
      note: A 200 means the request was accepted, not that every entity succeeded.
