SOAP Sender: WSDL

Hi Experts,

I have one confusion related to SOAP sender scenario.

After creating one interface in DEV environment, provide the WSDL , URL and Credential to Customer to push the data in PI.

But my question is, after transport to QA or PRD  need to extract again the WSDL from sender agreement from respective environment and again need to provide that? or WSDL and URL are same in all environment  for one particular interface?

Thanks,

Arthita
