Yesterday a lot of orders have not been published meaning they were not available for sellers to process. Today we manually pushed those orders but they contain the original delivery promise causing performance issues. This means that some orders will be available today but also have a delivery promise set for today. This is not a API specific issue but sellers might be contacting their developers hence this publication.
Refer these sellers to our information post on https://zakelijkverkopen.bol.com/storingen/vertraging-orderverwerking/ or ask them to contact our Partner Service.
