Everything you need

A focused SMS platform with the essentials — no bloat, no complexity.

Simple REST API
Integrate with standard GET requests. No SDK required — curl, PHP, or any HTTP client works.
Multi-tenant accounts
Separate SMS accounts and API keys per customer. Manage everything from the customer portal.
Delivery tracking
Every send returns a transaction ID. Poll delivery status until messages reach recipients.
Balance inquiry
Check remaining SMS credits programmatically before sending campaigns.
Secure API keys
UUID-based keys tied to your account. Rotate or revoke keys anytime from the portal.
JSON & XML responses
Choose json (default) or xml via the format parameter. JSON responses include friendly error messages.

    Get your API key

    Sign in to the customer portal and create an API key for your SMS account.

  2. 2

    Integrate

    Add a GET request to your app using your key, destination number, and message text.

  3. 3

    Send SMS

    Messages are routed instantly. Track delivery with the returned transaction ID.

One request to send

Authenticate with your API key, pass the destination number in 923XXXXXXXXX format, and your message. Responses include a transaction ID for tracking.
