Important Note #

These message types are available only on the SMSGatewayCenter UI for ease of use. When using the WhatsApp Business API directly, you must send messages in JSON format, which our system handles automatically when you use the UI forms.

This variety of message types allows you to engage customers effectively with text, media, and interactive elements. For further assistance, contact our support team at contact @ smsgatewaycenter . com or call +912228657726.
