Webhook with URL Parameter Replacement not working

I do not have ability to write server side script in the webhook script.
I can only do client side.
So, I was thinking I will pass the value of email field as a url parameter so I structured my webhook url as

But when I parse the url parameter in my webhook script i get empty string.

Any possibility to get data in client side.

Hi @digamber, I am not sure if you are sending this to Unbounce or from Unbounce as a webhook to another app.
