Pinterest Conversions API via sGTM — Custom events showing as UNKNOWN
Hey everyone,
I'm currently setting up Pinterest tracking via server-side GTM using the **Pinterest API for Conversions Tag** from the Community Template Gallery.
Everything works fine for Pinterest standard events (page_visit, lead, checkout, etc.) but I'm having an issue with custom events.
Setup:
- GTM client-side: Pinterest Tag template firing custom events
- sGTM: Pinterest API for Conversions Tag with Override client → Custom Event + Lookup Table mapping GA4 event names to Pinterest custom event names
- event_id passed on both sides for deduplication
Problem:
In Pinterest Test Events, my custom events show up as UNKNOWN instead of their actual name. The raw event name is correct in the parameters but Pinterest doesn't seem to recognize it.
Does Pinterest CAPI actually support custom event names ? Or are we limited to the 9 standard Pinterest events ?
Has anyone managed to get custom events working properly via sGTM + Pinterest CAPI?
Thanks in advance!
