  title: API Evangelist enhancements for MailerLite Automations Fields API
  version: 1.0.0
extends: openapi/mailerlite-fields-api-openapi.yml
x-generated: '2026-08-13'
x-method: generated
x-source: https://developers.mailerlite.com/ + the API Evangelist artifacts in this repo
x-note: 'MailerLite publishes no OpenAPI of its own, so the document this overlay extends is an API Evangelist
  derivation from the published reference. This overlay carries ONLY the API Evangelist enhancements —
  the runtime semantics MailerLite documents in prose but that no machine-readable contract states: cursor
  pagination, the X-Version pin, the two rate limits and their headers, the Laravel-style error envelope,
  and the absence of an idempotency-key contract. It never mutates the source document.'

    x-rate-limit:
      global: 120 requests per minute per account
      import: 5 requests per minute on import-creation endpoints
      headers:
      - X-RateLimit-Limit
      - X-RateLimit-Remaining
      - Retry-After
      status: 429

      example: '2038-01-19'
      default: latest
    x-idempotency:
      header: null
      supported: false
      note: No Idempotency-Key contract. POST /api/subscribers is a natural-key upsert on email and is
        safe to retry; every other write is not.

      shape: '{"message": string, "errors": {field: [string]}}'
      note: Laravel-style validation envelope served as application/json.
    x-pagination:
      style: cursor
      params:
      - limit
      - cursor
      response:
      - links.next
      - links.prev
      - meta.next_cursor
      - meta.prev_cursor

      endpoint: POST /api/batch
      max_requests: 50
      note: Webhooks are not supported in batch requests.
