How do I connect my custom form using the webhook?

In your SMSGatewayCenter panel, go to Integrations → Contact Form Integration and copy the webhook URL (e.g., https://unify.smsgateway.center/integrateContactFormWebhook/?uid=xxxxxxxxxxx). Configure your form to send data to this URL using GET or POST methods, including required parameters: name and mobile (with country code), and optional email and comments. Example GET: https://unify.smsgateway.center/integrateContactFormWebhook/?uid=xxxxxxxxxxx&name=John%20Doe&mobile=919876543210. Secure the webhook with HTTPS and keep the UID private.
