I wanted to send conversions to GA4 every time event in Google Calendar ended.

I did research for it and I found out that Send Measurement Events for an Application problem will be the best option.

I configured everything, but when it comes to setup event parameter it doesn’t work. Because one of the parameters is dynamic it crashes event sending:

 

 

But when I just type it like this:

It works!

The thing is I can’t do dynamic parameters value what google gives us to do, to measure it more detailed way…

Even its the same text in input data:

{"name": "rezerwacja_zapier", "params": {"currency": "PLN", "value": 200 }}

I even tried ZAPIER AI to make it just as a text and use output data as a JSON formula for GA4 event, but didn;t help.

 

 

Hi ​@Global Sales,

Welcome to the Community! 🎉

It looks like you’ve reached out to our Support Team about this and they replied with a suggestion. I’ll share details of the suggestion here in case it’s helpful:

I had a look at the Zap run you shared, and I see what is known as a placeholder error.
 
Whenever you see curly braces around entries in the 'Data In'of an action, this means that there is a field mapped there in the Zap Editor, but when the Zap ran live, this data was empty or didn't exist in the same way it did when you set up the Zap.
 

To resolve this issue, load new test data in your Zap trigger, re-test the AI by Zapier step 3, and then re-map the affected fields in your Google Analytics step again.
 
You can read more about how to fix this here: https://zapier.com/help/troubleshoot/behavior/zap-trigger-isnt-sending-data
 
I hope that helps! Let me know if you have any other questions, and I'll be more than happy to assist.
 
Best Regards,

If you’ve got any questions regarding their suggestion it would be best to continue the conversation with them over email. If you can’t locate their reply I’d recommend searching your spam/junk folder or searching your inbox for any emails from zapier.com in case. Sometimes their emails can end up in the spam/junk folder by accident.

Troubleshooting dynamic parameters in GA4 can be tricky, especially when automation tools like Zapier don’t parse them correctly. Have you tried formatting the JSON differently or using a custom function to process dynamic values? GA4 events need properly structured data to track user interactions.
