GTM Server + FB CAPI deduplication stuck

I read this article on FB CAPI event deduplication. (How to set up Facebook event deduplication in Google Tag Manager - Stape)
Unfortunately, I didn’t get far in the configuration, I got stuck in step 4 (Add this variable to all Facebook tags you have inside the Web Container. ), because that’s how GTM is configured for me:


  1. If you wish to keep web tags as custom HTML, dig through this Avancé - Pixel Meta - Documentation - Facebook for Developers - you can still put unique event id there

  2. But I suggest you switch to templated tags instead, those are much easier to understand and maintain.

In both cases, the approach from the tutorial still applies.
