Hello @raiwa
thanks for your very fast reply. I will forward my question. I asked at this "place" cause I was most likely to suspect a clue here due to the thematic proximity.
Maybe some will show up with an idea.
Anyway thanks again for maintaining this addon!

Hello @philpla
I have a quick and dirty solution that works for me... it's an adaption from an answer at the dev-portal as there is / was no official guide how to use it in php when I needed it. There is a quite interesting work at github https://github.com/Petschko/dhl-php-sdk which deals about this more deeply but as my solution worked for me I never implemented this into my system. 
so goto https://github.com/cupidare/dhl-labels
this applies some changes to orders.php in admin and adds a new file which needs your login/profile information. Please not that every comment is in german. This was never thought as an official module as I am no professional coder. That's why it is far from modular and very basic. 
Additional create a folder where to store the labels (in this case dhl_labels)
The idea is to go to the order in admin, enter the weight of the package and create the label. 
This is based on v.2.2 of the dhl-api. It should still be working despite v3 is available.
