description: >-
  Forter does not publish fixed numeric rate limits for its Decision API in the
  public documentation. The API is a real-time, synchronous decision service
  called inline at checkout, signup, and login; throughput is provisioned per
  account to match the merchant's transaction volume rather than governed by a
  published per-minute request cap. Practical limits, timeouts, and failover
  behavior (for example, how to handle a timeout or a non-2xx response at
  checkout) are defined per integration during onboarding.
notes: >-
  No public per-account or per-endpoint numeric request-rate limit is documented
  as of the review date. Confirm your account's throughput allowance, request
  timeout expectations, and recommended fail-open / fail-closed behavior with
  Forter during integration.
