Hi @ALake2,
Nothing much more to add from @PamCotton’s post other than a couple links.
I refer to the app page for each Zapier integration often when trying to understand capabilities of a connection. Scroll down on each link I provide and you’ll see the triggers and actions supported. With a paid plan, you can leverage Zapier’s webhooks to make API calls if the trigger or action step you want is not built natively in Zapier.
Here’s HubSpot’s integration page
Here’s MRPeasy’s integration page
If you want to share a specific use case you’re after, I’d be happy to attempt a solution with some screenshots.
Here’s a help article on how to connect an app in Zapier.
