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.

Fresh API

The Fresh API uses the same format of requests and responses, and is subject to the same limits, as the Content Delivery 2 API and Filter API. There are also some additional rate limits:

Feature	limit	Description
API requests	100 requests per second. Burst limit: 200 requests per second	This 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.

• A content item snapshot is saved to an edition or content is added to a slot in an edition
