DHL API > how to pass the parameter printFormat

Question

I use the current REST API 2.1.1 of DHL Paket DE Versenden (Post & Paket Deutschland).

There i can pass a parameter namend printFormat to specify the label size. But I do not know where exactly to pass the printFormat.

When I pass it by the header like stated in the documentation I get an error. And when I pass it within the post parameters as JSON I get also an error 400 > Blocking error.

Where the hell do I have to pass this parameter? Normally I can set the standard label in the profile of the user portal. But it seems that it's ignored.

Any help is appreciated.

The parameter has to be passed as query parameter in the API URL:

POST /parcel/de/shipping/v2/orders?printFormat=910-300-600 HTTP/1.1Host: api-sandbox.dhl.com
