Apple Shortcut Query

Is it possible to:
Start a shortcut from Siri that sends data to Pabbly and has an action process then send that data back to the shortcut?
I have been able to use Siri to dictate text and send to the webhook in Pabbly. Then it is processed by the action.
However, i am stuck on how to send that information back to the shortcut. I want Siri to read it out.
I was thinking of using an API but Apple Shortcuts doesn't have the capability to create an endpoint URL and Pabbly won't let you send the API update back to the original webhook url.
Is there any tricks i don't know about?
