Suddenly Purchase events sometimes missing

[Daniel-NF]

Hi,
i have a totally strange behavior for some days now and i cant figure out why. I am using stape server side tagging for many months now.

My checkout process has events like add_payment_info, confirm_order and of course purchase. The value is included in every event.

For some strange reasons i am missing purchase events (but i know that the custoemer ordered). The strange is that i can see the add_payment_info and confirm_order event server side … (because of the value paramter) but the purchase event is sometimes missing.

I tried to catch the purchase event with data tag to be sure and there it is working fine.
user_data is in the event parameters and not with the toggle on on web tag container.

I checked network tab - everything is going threw server url.

I am out of ideas… is there something google changed perhaps with the user_data or something else?

just found an article here and will try that now, maybe that helps

Purchase only 302 http status code

Hi Petyabaa, We’re experiencing similar issues. The event is collected at all points, except in GA4. Server side tags returns 302 as well. Have you had any break-throughs concerning this issue? thank you

In the case of GA4 the 302 code is normal, there is no need to do anything about it.

Have you checked the consent? Perhaps at the purchase stage your consent is not working correctly? You can see the consent status that is sent in payload events - this is the ‘gcs’ parameter.
‘gcs=G100’ - consent rejected.
