We’ve been having the same issue since last year. We’re extremely disappointed that there’s so little transparency nor communication around this topic. Even Support doesn’t get updated on the progress of this issue, which leaves absolutely everyone in the dark.
It would be greatly appreciated if the developers would give a status update after nearly a year of this ongoing issue.
Thanks for letting us know,
In the meantime, the last time I checked it appeared to be working. I tried creating a conversion event and that was added without error:
And I was again able to load a Data Stream successfully:
So I’m wondering if something may have changed on Google’s end that means it now requires different/higher permissions to be able to access the Data Streams. Can you confirm what role/permissions the connected Google Account you’re using currently has?
Looking forward to hearing from you!
I've been facing the same issue since last year.
Please let me know when it's resolved. Thanks.
Really sorry you’re being affected by this as well
Please add me to the list to be notified of this fix as well.
You got it,
Please add me to the list too.
Thanks for reaching out here,
Please add me to the list as well. Disappointing to see this has been ongoing issue for so long.
FYI, I just tried adding as a measurement and not conversion event the way you mentioned and neither works. Both give the same error. Please add me to your list.
Who can we complain to on social media about this issue that’s existed for years evidently?
Any update on this? I see a Zapier employee replied saying it applies to create measurement, but I get the same error on create conversion event.
I’m so sorry to have missed your messages here
I’ve just checked on the bug report and there’s still been no change in the status of the bug.
There were two separate issues mentioned in the original topic post:
Can you confirm:
Can you confirm whether you’re seeing a “Failed to create conversion event” error OR a similar “Unable to load choices” error on the Create Conversion Event for a Property action? There’s a separate bug report open for that second issue which I can add you to but I wanted to double-check which error you’re seeing before adding you to that.
Looking forward to hearing from you all on this!
Just ran into this issue too. SSO with Google succeeded, it pulled in correct property and let me setup an Event name. I can even see the new Key Event created in GA4. However, when I click “Test step” or “Retest step”, it fails with an unspecified error. It’s really annoying that Zapier does not show any technical details in this case whatsoever.
So… Does Zapier not work with GA4? Is there a workaround for creating conversion events, like using the GA4 API? If yes, can you please provide an example what to enter into the below form?
UPDATE: I tried using the API Beta feature. (BTW Copilot is useless in telling what values to use; Claude did it). Here is what I used:
{
"client_id": "{{random_uuid}}",
"events":
{
"name": "Flodesk_subscriber_created",
"params": {
"engagement_time_msec": 100,
"session_id": "{{session_id}}",
"property_id": "<my ID>"
}
}
]
}
The response shown in Zapier test request shows HTTP 204 error (= No content). Any ideas what’s wrong?
you’re going to want to learn how to do what you need with Google Tag Manager. Zapier thing been going on way too long to wait for a fix here.
