Send CMS items with form submission to Airtable (using Webhooks)

Hi I have a simple form submission with the field you would normally expect; first name, last name etc. I want to send particular CMS items that are shown on the page with the submission form which is sent to Airtable.

I already have the Webhook configured and the form works, it’s just needs to be able to send the CMS items too.

Any suggestions?
