Bulk SMS API & SMS Gateway
Enterprise-grade SMS API for reliable, scalable business messaging. Send transactional SMS, OTPs, alerts, and campaigns globally with high deliverability and sub-second delivery.
What Is the SMS API?
Our Bulk SMS API is a programmable SMS gateway that lets you send and receive text messages from your applications, CRM, or backend systems. Use it for one-time passwords (OTP), order updates, appointment reminders, marketing campaigns, and more — with a single REST API across 200+ countries.
How It Works
Integrate once and send SMS from anywhere in your stack.
1. Connect via REST API
Authenticate with API keys and send SMS with simple HTTP requests. Our REST API supports JSON and form-encoded payloads with full documentation.
2. Send Messages at Scale
Queue high-volume sends with priority routing. Use templates for transactional messages and personalization for campaigns.
3. Receive Delivery Reports
Webhooks push delivery status and DLR into your app in real time. Track bounces and retries for reliable messaging.
4. Monitor in the Dashboard
Use our analytics dashboard for delivery rates, costs, and performance by region or campaign.
