Hey @ashley c13​ , 👋 thanks for reaching out! I'm one of the Support Engineers here at Intercom!

You can definitely send messages to users based on certain purchases they make on your website. You can use event triggers within Intercom.

So you trigger an event for a specific user when they purchase an "in-person event" then you can have your messages send based on these event triggers.

Here is an article which runs through this further and in more detail.

Thanks!
