Send Quick WhatsApp for SMSGatewayCenter APIs
Introduction to SMSGatewayCenter APIs
Welcome to SMSGatewayCenter’s API documentation hub! This guide introduces the Send WhatsApp Message API, a key component of our messaging suite, including SMS API for bulk messaging, WhatsApp Business API for customer engagement, Voice Call API for automated alerts, and Two-Way SMS API for interactive communication. This API supports only POST methods over HTTP, enabling you to send personalized WhatsApp messages using templates. Ideal for developers in India, integrate with our SMS gateway at unify.smsgateway.center/signup/!
Use the Send WhatsApp Message API to deliver real-time order updates or notifications (e.g., order dispatch details with variables like order number, delivery time, and status link) via WhatsApp. This endpoint enhances your bulk messaging strategy with secure, template-based communication and high deliverability.
