Trigger a pop-up upon a specific purchase

Hey guys,

So I’m building a site for a friend. It’s a WooCommerce store. There are many physical items to purchase in her store. My friend also offers live video tarot readings via Instagram and Telegram.

Say, for example, someone adds a bunch of physical items to their cart as well as a tarot reading? They pay for all items and then a trigger of some kind happens or some kind of an event occurs so that when any of the 4 tarot readings (within that category) have been identified as paid for, a pop-up window of her Calendly shows up so that the customer can instantly book their reading slot once the full transaction has been completed.

I didn’t want to have the Calendly page or link displayed on a page somewhere on the site, because people might simply take advantage of that. This would also mean that my friend would have to keep checking to see if a tarot reading had actually been paid for. And I don’t want to create extra admin work for her.

Would anyone know if there is a simple way to create such a pop-up upon a specific purchase?

Or, is there a hook out there for this? I had a look here – https://developer.www.ads-software.com/reference/hooks/ – but wasn’t really sure what hook I was looking for. Not even sure if a hook is an answer.

I’m just hoping to make this process as automated as possible and thought a pop-up could work. But not sure how to do it for all 4 tarot readings which my friend offers.

Any tips or guidance would be awesome.

Thank you,

Kate
