How receive response from web servcie in appsheet

[David_Joyce]

Hello
There is a web service that optimizes routes. So you feed it a list of GPS lats and longs, and it returns the list in the order that costs the least amount of fuel, shortest distance or something.

Question: How can I capture any response that comes back from calling the web service from inside my app? I looked at webhooks but it didnt seem possible there.
