Using Airtable Webhook With Wix

I saw within the Wix automations section that you can attach a webhook.

Using this, I have wix sending order data to Airable via this web hook, for every order.

The issues I am facing is not being able to send MORE data because the webhook variables are not able to be changed.

So, I am now under the impression that I have to embed this webhook within the code of the order page but Need a little assistance. Can anyone help?
