This usually happens when a custom parameter exists in Invoca but hasn’t been created in GA4 — GA4 rejects events that reference parameters it doesn’t recognize.
Symptoms
- Conversion events aren’t populating in GA4 reporting.
- Invoca logs show 204 success responses.
Cause
A custom parameter was created in the Invoca Action but not in GA4. GA4 rejects any events sent using a parameter it doesn’t recognize.Resolution
- Confirm the event names match exactly between Invoca and GA4.
- If using custom parameters, confirm those same parameters exist as Custom Dimensions or Metrics in GA4.
