About the session
Meta's Conversions API is powerful but fragile. When something breaks, optimization quietly stops working, conversions drop, and no one knows whether the issue is in Meta, GTM, or the server.
This recording will help you understand what's really happening behind your setup and how to fix it.
What you'll learn
On-demand troubleshooting workshop
Hosted by Barbara Galiza and Timo Dechau. We map how Meta CAPI works and show the most common points of failure in real-world setups, including highlights from the live Q&A.
Learn how to recognize the signs of broken CAPI events
Understand why those issues happen in the first place
See how to validate your setup using Meta's diagnostic tools
Watch real examples of broken CAPI setups get debugged step by step
What we'll cover
From browser to server to Meta
We'll go through the CAPI flow step by step and explain where signal loss typically occurs. You'll learn how to identify and prevent:
- Event mismatches between browser and server
- Deduplication errors caused by missing or inconsistent event IDs
- User parameter problems such as missing or unhashed data
- Timing and delivery issues with delayed or invalid payloads
- Validation warnings that reduce signal quality
The goal is to help marketers and technical marketers understand what breaks, why it matters, and how to fix it.
