FAQ

SMS Gateway API — Frequently Asked Questions

How do I integrate the SMS API?

Create an account on our new platform, generate an API key, and call the REST endpoint with your message, sender ID and template ID. We provide code samples for PHP, Python, Node.js, Java and cURL — most developers are sending within an hour.

Do you support delivery reports (DLRs) via webhook?

Yes. Register a callback URL and we push delivery status per message in real time — delivered, failed, or expired — with reason codes. You can also poll status via API or view it in the dashboard.

Is there an OTP-specific API?

Yes — a dedicated OTP endpoint generates, sends and verifies one-time passwords on high-priority transactional routes, with configurable expiry and retry, so you don't have to build OTP logic yourself.

How is the API secured?

HTTPS-only, per-account API keys with rotation, IP whitelisting, rate limiting and full audit logs. Enterprise accounts can enforce role-based access for team members.

What about DLT compliance through the API?

Every API send is scrubbed against your registered DLT templates and headers automatically. Pass your template ID with the request and the platform handles entity ID mapping and compliance.

Is there a sandbox for testing?

Yes. Demo credits let you test against your own number end to end — request, delivery, webhook — before going to production.
