Hello @pstidsen, I visited the website you mentioned and noticed that in addition to our default e-commerce event, you’ve also created events using the Event Setup Tool in the Meta Event Manager settings page, such as AddToCart and InitiateCheckout. I couldn’t test a purchase event, but I assume you might have a Purchase event there as well.
I recommend removing any event created with the Event Setup Tool, clearing all caches, and then conducting a CAPI test for the purchase event to ensure that we are correctly sending both server and browser events.
Let me know how it goes.
