    Derived from openapi/leanplum-api-openapi.json (Leanplum's own published spec)
    plus https://docs.leanplum.com/reference/responses,
    https://docs.leanplum.com/reference/batching-requests and
    https://docs.leanplum.com/reference/making-requests.
  note: >-
    Non-destructive. Adds the metadata Leanplum's published document omits —
    contact/licence, tag descriptions, and the error codes the docs describe in prose
    but never declare in the spec (429, 451, 5xx). It does NOT invent request or
    response schemas, and it does NOT add operationIds, because inventing an
    operationId would create an identifier that does not exist in Leanplum's contract.

      Active. Leanplum was acquired by CleverTap in 2022; the REST API remains
      operational during customer migration to CleverTap, which has wrapped its own
      methods behind these Leanplum methods.

      description: >-
        Too Many Requests. Either strict device locking (concurrent requests for the
        same userId are serialized and the loser fails) or the devMode rate limit of
        1 request per second per device. Retry with exponential backoff; no
        Retry-After header is sent.

    '451':
      description: >-
        Unavailable For Legal Reasons. Returned when the call attempts to update a
        userId that has been blocked with the `block` method.
    '500':
      description: >-
        Internal server error. Retry with exponential backoff up to a bounded retry
        count.
