Right now, i am trying to use the DHL Shipment Label API Shipment Label API Docs
But i cannot seem to find on the Auth request, what is the client_id and the client_secret The only thing i have from my registered app is the API_KEY and the API_SECRET and that gives me a 401 error code
Any help is amazing!
i had also to fight with the documentation ;-)
That's how my CURL HEADER option looks like:
I concatenate username and password with a colon and make a base64 encode. And I pass the api key through the parameter dhl-api.key
