Callouts not firing in sandbox (or how can I effectively test callouts)


I have an apisandbox.zuora.com (Zuora test drive) account.

I log in to the UI, go to Settings->Payments->Setup Profiles, Notifications and Email Templates and configure the Payment failed and Payment processed notifications with Callout delivery. I've set up the callout base URL to a working URL (accessible via the internet). I've set the callout content type to application/json and explicitly left the authorization settings unchecked. I checked the two notifications as Active. I've attached a screenshot of my settings.

I'm trying to find a way to test some callouts and check out the request bodies. Is there a way to do this?

I tried creating a new payment from the UI (Payments->Create payment) but no notification was triggered.

What's the best way to test callouts?

Thank you.
