I have a static HTML website where visitors request a quote through a simple form. As soon as that form is submitted I want an automated WhatsApp Business message, triggered by Meta’s Graph API, to reach the visitor. Scope of work • Hook the existing form’s “submit” event to Meta’s WhatsApp Business Cloud API. • Compose and send one personalized thank-you message that also echoes every field the user just filled in. • Handle authentication (access tokens, webhook verification) from my own WhatsApp Business account created in Facebook Developer. • Provide clear variables so I can tweak message copy or add new form fields later without touching the API logic. Acceptance The project is finished when I can run a quick test in production, submit the quote form, and see the WhatsApp message arrive instantly—complete with all form data and my custom thank-you text.
