Certificate Validation Via Webhook

Has anyone created a URL like e.g. **domain.com/verify** on WordPress?
I am trying to create a form on WordPress that will send a certificate ID to a Webhook (Checking Google Sheet as DB via Zapier) and then display a success (certificate found) or error response on the page.

I have Elementor Pro (if that helps)

How do I achieve this? Thank you.
