WA->SendTextMessage("+34666555444", "hello from Delphi");Combines an HTTPS Cloud API client with a built-in Webhook HTTPS server so a single Delphi process handles outbound and inbound traffic.
SendTextMessage, SendTemplateMessage, SendMediaMessage, SendInteractiveMessage, SendLocationMessage and SendContactMessage cover the main Cloud API content types.
The component embeds a TsgcWebSocketHTTPServer to host the verification + delivery webhook required by Meta. OnInboundMessage and OnStatusUpdate deliver typed events.
OAuth Bearer authentication via CloudOptions.AccessToken; verify-token check happens automatically against CloudOptions.VerifyToken on the first webhook GET probe.
SendTemplateMessage accepts named/positional parameters, language code and the component sets the typed structure Meta requires.
The component handles the multi-step Cloud API media upload (upload → obtain media-id → reference in send) when you call SendMediaMessage with a local file path.
Configure the embedded server's SSLOptions for HTTPS — Meta requires the Webhook to be reachable over TLS. WatchDog handles port re-binding on certificate rotation.
