Since 14:30 we have some problems with our Orders and Returns endpoint.
Therefore you are not able to do a GET and PUT/POST on the whole Orders endpoint.
For return we can not provide the order information.
Make sure to check the process status of all the PUT/POST request.
We will update this message at 15:30.
We apologize for the inconvenience.
We still have the same problems, we will update this message at 16:00
Everything is working again.
