summary: >-
  Accela enforces per-app rate limits and returns standard-shaped rate-limit headers, but publishes no
  numbers. The limit is configured per app, per agency, by the agency itself in the Agency Admin Portal — so
  there is no single figure Accela could publish, and a client cannot learn its ceiling from the
  documentation. It has to read the headers. Note this became real only in the June 2026 release: before
  4.6.5.3 the per-app limits configured in the Agency Admin Portal were not enforced at all.
limit_count: 0
limit_count_note: >-
  Zero published numeric limits. This is an honest zero, not a missing measurement: the values are
  agency-configured and Accela documents the mechanism rather than the number.

  statement: >-
    "Previously, per-app rate limits configured in the Agency Admin Portal were not enforced. Now, requests
    that exceed the configured limit return an HTTP 429 (Too Many Requests) response and include the
    X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers."

  retry_after_note: No Retry-After header is documented; use X-RateLimit-Reset.

    description: When the window resets.
limits: []
contract_gap: >-
  None of the 417 published operations declares a 429 response. An agent generating a client from the
  Swagger documents alone will not handle rate limiting at all.
