Purchase event fires only as Browser event

[MariuszMilka]

I have a simple setup of events. On each landing page there is a buton to sign up for a course, which is set as "initiate checkout" event. And this opens a popup with a form o provide name, pbone number and email and it hase a "send" button which is set as "purchase" event. Up until recently it worked on all website my agency administrates. However, recently something has changed.

Now "initiate checkout" sends both browser and server event to the pixel, but "purchase" sends only a browser event. What is interesting is that I can log in to wordpress and send a test "purchase" event and then it appears in pixel as both server and browser event. But when it is actual people making the purchase, not a test event, only the browser event reaches the pixel.

So everyting is set up peoperly, both the plugin and event managr tell me the connection between them is active. All test events, including "purchase" reach pixel and appear both as server and browser events. So the plugin is able to send server events. But for some reason it doesn't for "purchase" event only. All other events appear in pixel as server and browser, but purchases from real people only show as browser events.

The problem is not isolated to one site and one pixel. I have it on all. And on all of them this used to wrok properly. There was an update to the plugin a few weeks ago and this was around the time the problem started, so it might be related to the last updates.

Hi @MariuszMilka,

Would you mind sharing the URL of one of the affected landing pages so we can review the implementation and inspect how the events are firing? This will help us better understand what might be going wrong.

Thanks!

You can try with this one: https://blueholediving.com/diving-course/scuba-diving-course-in-gozo-open-water-diver/

"Sign up for the course" button should activate an "intiate checkout" event. Then the "Book now" button on the popup should activate a "purchase" event. And they do, but on the pixel side in the Integration column next to Purchase events, I only see "Browser" and "Multiple" next to all other events including "initiate checkout" that is fired from exactly the same page.

However, test Purchase events reach Pixel via Conversions API, only the real Purchase events don't.

Hi @MariuszMilka,
Thank you for providing the URL to one of the affected pages. We have confirmed that the browser-side Purchase events are firing.
To help us properly investigate the issue with server-side Purchase events not appearing, could you please provide the following details:

1. Date range of when the issue was observed (e.g. a specific date range)
2. Expected number of Purchase events (server-side/CAPI) during that period (based on actual conversions/bookings).
3. Actual number of Purchase events received in Events Manager via Conversions API (CAPI).

This will help us identify whether the issue is with missing server events entirely, or with them being sent but not recognized or matched by Meta.

1. End of June until now.
   2 and 3. I do not understand... At the end of June i updated to the newest version of the plugin and around the sane time I noticed that all Purchase events are now Browser events only. So it is not a case that sometimes server events don't fire. They jiust stop firing for Purchase event and have never fired again. I am not missing purchase events. But tgey just arrive from the browser side only.

Hi @MariuszMilka,

Thanks again for the update. Could you please provide screenshots of the Purchase event graph from Events Manager, ideally filtered to the relevant date range, where it's visible that no server-side Purchase events were received?

This will help us better understand the discrepancy.

It is difficult to produce a screenshot of something that is not there at all...

Here you have the overview of the pixel. In the integration column all events have "Multiple" apart from Purchase that has only "Browser".

Here initiate checkout on the top - both server and browser events and only browser for purchase.

And it is like that on all my accounts and all pixels. But I can send test Purchase events and they will appear as dots on the Pixel. Just the real Purchase events never reach it or never fire.

Hi @MariuszMilka,
Thank you for providing the screenshots of the Purchase event graph.

Could you please share the Site Health Info from your WordPress installation?
This will help us determine whether any conflicting configurations or plugins might be preventing the Meta Pixel for WordPress plugin from sending server events correctly.
