# GTM trigger for purchase conversion tags

On the HomeRunner confirmation page, trigger your purchase conversion tag on the custom event named `purchase`. The HomeRunner plugin pushes this event into the dataLayer when your PMS returns the reservation as confirmed.

**Why not a page-URL trigger.** A page-URL trigger fires before the `purchase` push lands. As a result, the order ID and value arrive empty, page refreshes cannot be deduped, and inquiry confirmations are counted as purchases.

**Lead tags.** When the booking is not yet confirmed, use `generate_lead` as the trigger for your lead tags.
