API Rate limits

Rate limits are the limits imposed on the number of requests, or requests/calls, you can make per hour/minute/second via the API.

Why there are Rate limits

When many API requests are sent to our systems at the same time, this can cause problems. Without Rate limits, services could become overloaded, leading to a delay or failure.

This is how Rate limits are determined

We aim to set the Rate limits so that each partner can execute the desired number of requests within a number of seconds or minutes. Rate limits are set per endpoint. A higher limit is available for one process than for another. For example, the limit for price changes is higher than for accepting a return. The capacity of the systems is designed so that important sales processes are given more space than processes that are less time-sensitive or run less frequently. Rate limits are set accordingly, based on historical usage and growth of the API by all partners. An overview of all Rate limits per endpoint can be found here.

Can my rate limits be increased?

For partners handling an exceptionally high volume of orders or offering a significantly larger than average range, it is sometimes difficult to optimally execute their processes within the current limits. There is limited scope to grant higher rate limits in these cases. Higher rate limits are only granted when the API integration has been optimally set up by the partner, but the standard rate limits are nevertheless insufficient. Eligibility for higher rate limits is assessed on a case-by-case basis.
