enforcement:
  - Limits are enforced at the API key level, not the account level
  - Exceeding per-second rate limit returns HTTP 429 Too Many Requests
  - Custom rate limit increases can be requested via MYOB support portal
notes:
  - Legacy documentation referenced 5 requests/second and 50,000 requests/day; these are outdated figures
  - The my.MYOB portal may display incorrect rate limit information; community-confirmed values above are current
  - Rate limits do not differ by developer program tier (Developer Access, Developer Partner, Premium Developer Partner)
