Fortnox will raise its API rate-limit and make changes to the current ‘sliding window’

On 15 November 2022, Fortnox will increase the current rate-limit of 4 requests per second (240r/m) to 5 requests per second (300r/m) per access-token, which is an increase of 25% from the current limit.

When this is applied, there will also be a technical change of the implementation of the rate-limit. Today, the rate limit is calculated during a one minute ‘sliding window’ approach. The new implementation will be calculated during a five second ‘sliding window’, making it more granular and distributing the amount of requests more evenly over the same amount of time.
