Hello,
The webservice I'm trying to call has resources like shown in attached screenshot. I'm not sure how to pass these resources in Integration component either.

Isn't the resource an example of a path parameter, can you not simply append it to the endpoint in the URL of the Integration object?
If the resource is static, e.g. it will never change, then it could simply be entered as part of the URL, but if it needs to be dynamic, e.g. it could change dependent upon rule inputs for the integration, then you would need to use an expression for the URL.
