Eventbrite embedded checkout ecommerce tracking

Hi EventTribe!

I hope you can help me…

We are launching events through our website using the Eventbrite embedded checkout functionality. I need to track users when they interact with the iframe and make a purchase so that it is recorded in Google Analytics.

I have managed to set up the Cross-Domain tracking successfully, however I am not seeing any transactions being recorded in the ecommerce section of GA.

I have followed this guide https://www.eventbrite.com/support/articles/en_US/Troubleshooting/how-to-enable-cross-domain-and-ecommerce-tracking-with-google-universal-analytics?lg=en_US and https://onefurther.com/blog/eventbrite-google-analytics-ecommerce-tracking-cross-domain which puts me under the impression ecommerce tracking should be happening out of the box?

Any help would be greatly appreciated!

Thanks,
Margaux
