Can you configure output payloads from WMS?

Summary:

There does not seem to be an option that I can find, but was WMS allow for configuring or defining of output/input payloads or do you have to go through a middleware for transforming and mapping of data.

In my example, we are looking to connect to Purolator parcel service via API and would like to integrate to our WMS environment.
