Process Integration - GET requests - How to handle return object

Hi,

I'M having trouble finding documentation on how to handle GET request within Service desk process integrations.

I would like to be able to call an API whether in solarwinds service desk or a external source, and be able to put the response into a comment / or custom field. do something with what is returned.

Is this intended to be more for a webhook type of feature for 3rd party api?
