Take a look at https://github.com/ibm-datapower/datapower-tutorials/blob/master/getting-started/hello-world-gateway.md

You can explore it as a way to get started and see how things works. There are a few other tutorials in the same folder.

Typically, what you want is:

• created a Multi-Protocol Gateway
• add an HTTP/HTTPS Front Protocol Handler that listens on the port where you want to receive requests on
• configure the backend URL where you will send requests to
• create a multi-protocol gateway processing policy
