TMS FNC WhatsApp Server — Guides
Starting the webhook server
Set Port, configure your SSL certificate, then set Active := True:
{ Start the WhatsApp webhook server on port 443: }
WhatsAppServer1.Port := 443;
WhatsAppServer1.Active := True;
Webhook verification
WhatsApp sends a GET challenge request when you register the webhook URL.
Handle the OnVerifyToken or equivalent event to return the hub challenge
value that WhatsApp expects, confirming your endpoint is valid.
SSL setup
Configure TLS version and certificate details through the SSL properties before
setting Active := True. A valid certificate from a trusted authority is
required for WhatsApp webhook delivery.
