Guestcentric Google Tag Manager (GTM) integration provides 9 custom events that can be used as triggers to fire GTM tags.

The available events are described on table below. Event names are case sensitive.

GTM integration integrates with Google Analytics and Analytics E-commerce. So on every event the analytics data (if available) like campaign, source and medium are pushed to GTM. E-commerce transactions (name, sku, price) are also automatically pushed on booking engine conversion events.

We also make available some more extra data if you want to use your own customized conversions, pixels, etc.

The available data depends on the event.

For other Booking engine events: selectoffer, booknowoffer, expandpromo, booknow and cancelcheckout, the available variables are:


For the bookproducts event, the available variables are:


For the cancelnow and cancelnowproducts no variables are available.
