I am having CORS issue.

 

I want to ask why Zapier is blocking request due to CORS issue when I am sending data from GTM to Zapier for Facebook conversion API, that are Click ID (fbc)  and Browser ID (fbp) and other parameters as well. You can say server side. 

 

Please help me out.

Hi ​@Helal 

Help us have more context by posting these screenshots:

  • the encountered error
  • how your Zap steps are outlined and configured in EDIT mode with the field mappings visible

Please see the screenshots. 

 

In container loaded and Linkclick screenshots shows tags are fired perfectly, and FBP & FBC screenshot shows the values are also coming. But zapier webhook is not receiving any of these data, that are FBP and FBC as shown in Zapier.png. 

 

However, in WhatsApp Image PNGs shows the CORS error in Network tab when I click on button from my landing page (https://hrukniet.systeme.io/wallartbundle) which redirects the user to payment page URL (https://pages.razorpay.com/pl_PrBShUu7fAwnXc/view).

 

When I run the below command on Console I get the message which shows in the WhatsApp Image PNG

 

Landing page: https://hrukniet.systeme.io/wallartbundle

 

Payment Page: https://pages.razorpay.com/pl_PrBShUu7fAwnXc/view 

 

In conclusion, Zapier might rejecting the request coming from GTM or from my landing page URL. Please fix this or let me know if you need anything else. 

 

Thanks,

Helal
