Who this API is for

This API is commonly used by:

SMBs building internal or customer-facing applications
SaaS startups implementing OTP & transactional alerts
Web, Android, and iOS developers
Agencies and system integrators

Whether you code yourself or manage a small tech team, we support you through setup and go-live.

What you can do with our SMS API

Our HTTP API follows a simple request model and works across most tech stacks. With the API, you can:

Send OTP and transactional SMS programmatically
Trigger alerts and system notifications
Receive delivery reports via webhook (when available from operators)
Restrict API access using IP-based security (IPv4)
Create and manage multiple API keys per integration

The focus is on predictable behavior, security, and compliance — not unnecessary complexity.

Platforms & Integrations

The same API can be used with:

Websites (PHP, Python, Node.js, Java, etc.)
Web applications and dashboards
Android and iOS apps
Backend systems like ERP, CRM, LMS, or HMS

No SDK lock-in. One API across platforms.

Sample Code & Integration Help

We provide sample API requests and payload formats to speed up integration and reduce errors.

Delivery Reports & Timing

SMS delivery reports are generated by telecom operators
When reports are available, they are pushed to your configured webhook
Typical SMS delivery time ranges from 5 to 120 seconds, depending on network conditions

Delivery reports are also visible in the SMS Portal, with a default retention of 14 days. Webhook integration allows you to store reports long-term on your own system.

We prefer clear expectations over unrealistic promises.

SMS Portal Included

Along with API access, you also get a Bulk SMS Portal to:

Send SMS manually
Check delivery reports
Monitor credit usage
Manage sender IDs and DLT templates
Test messages

This is helpful for non-technical teams, testing, and fallback usage.

Security & Access Control

IP-based API access restriction (IPv4)
Multiple API keys for different apps or environments
Ability to activate, suspend, or rotate API keys anytime
API management secured with OTP-based authentication

For approved customers, encrypted message support is available for sensitive use cases.
