Limits

On this page we've included the various limits for the Dynamic Content APIs and general usage of the Dynamic Content app. Limits for Content Hub and apps are also included.

Rate limits

FeaturelimitDescription
API requests100 requests per second. Burst limit: 200 requests per secondThis rate limit applies to requests to the Fresh API

Requests to the Fresh API are tracked against the API keys assigned to your hubs. Each of these API keys has a rate limit associated with it. Exceeding the rate limit will result in 429 responses from the service. When receiving a 429, your code should attempt a retry after delaying the next request with exponential back-off.
