Wednesday morning we will be upgrading some of our databases which will result in downtime for the API, the seller dashboard and the webshop. Between 04:00 and 07:00 the upgrade will be ongoing and we expect that requests during this period will result in errors.
As such we advise you not to use the API during the maintenance window. If you do keep the API active then please check the process status of each request for errors as a failure or a time-out will mean that the requested change has not been processed.
Our apologies for the downtime but it is a necessary step to keep our services safe and stable.
