To gain access to the test environment, register at
https://sandbox.dhl24.com.pl/ for a cash account. A test customer number will be assigned to it by DHL in the next step. Please send your request for a test customer number together with your e-mail login to:
Technical Support Contact Form> Integrations with Other Systems – API Access and Technical Support. If you need access to both test and production environment, it is necessary to have / register two accounts (independent of each other). Once you have received your login (along with your DHL customer number - in the case of production access), we will create WebAPI access for you.
