Struggled with Measurement protocol to send purchase event through GTM
I'm completly lost !I started to use Google Ads for my B2C Saas and I need to send conversion event to it.
I use stripe as payment provider. So I use webhook on my backend to handle payment.success event and trigger an event 'purchase' with Google Measurement Protocol. It's working half of the time and and I don't see events in real time in the debugview.
🤔 My first question is Measurement Protocol the good way to do in this context ?
🤔 Secondly, is it possible to use Google Tag Manager to fetch purchase events from HTTP requests done with Google Measurement Protocol and relay them to Google Ads?
Backend -- (purchase event) --> GTM --> Google ADS (Conversion) & GA4
Here a payload example I use to test :
{ "client_id": "1770912193.1700571402", "user_id": "***************", "timestamp_micros": "1700585815945000", "non_personalized_ads": true, "events": [ { "name": "purchase", "params": { "items": [], "currency": "EUR", "transaction_id": "123456789", "value": 6.60, "debug_mode": 1 } } ] }
Using Google Measurement Protocol: Yes, it's a good approach for your scenario. It's designed for server-side tracking and fits well with your setup. The inconsistency in tracking might be due to implementation issues or data processing delays.
It's important to include the ga_session_id in your payload to ensure accurate session tracking and attribution in Google Analytics 4. This will help in correctly attributing the purchase to a session source/medium like Google Ads and also reducing issues like "not set" in your reports.your final payload should be sth like this :
events":[{"name":"purchase","params":{"items":[],"currency":"USD","transaction_id":"rte2319","value":1.001,"ga_session_id":1696098149}}]
