Custom/Premade SamCart Integration

I’m trying to drop a contact into a campaign when a specific product is purchased in SamCart. I’m currently able to have the contact created and have a tag applied to that contact when the product is purchased, but if someone has previously purchased that product, it will not apply a new tag. I need for a tag to be applied each time a person purchases that product so that I can automate them into the campaign each time a product is purchased. Both SamCart and Zapier seem limited with regards to this. Does anyone know of a custom/premade integration to solve this issue?

Have you tried using an API Goal in the campaign?

Hadn’t thought of that, but I’ll give it a shot. Thanks!
