Same Event ID Received for Many Event Instances (Shopify)

Hello. I set up my server side tracking using Shopofy Capi code (Facebook conversion API for Shopify - YouTube) as shown on this video.

But now, I am seeing error “Same Event ID Received for Many Event Instances” on my FB Event Manager. Does anyone know how to solve this?

Thank you.

There might be multiple reasons why this error occurs. I suggest adding Facebook Test ID to FB tags in the Google tag Manager server container and opening the preview mode for the GTM web and server containers. This way you’ll see what events and event IDs Facebook gets.
