What does the “Duration of the request accumulated” field actually control in a Rate Limit rule?

The “Duration of the request accumulated” field defines the time window (in seconds) during which incoming API requests are counted before the gateway processes them. In simpler terms, it’s the period over which the system accumulates and evaluates the number of requests.
For example, if you set:

  • Requests Allowed = 40
  • Duration = 18 seconds

It means the API gateway will allow up to 40 requests every 18 seconds. If more requests come in during that period, they’ll be throttled or blocked based on the rule.

This helps regulate traffic, avoid overloads, and protect your backend systems.
