Twilio API Integration
Programmable SMS, voice and OTP verification across 180+ countries.
What Twilio API integration does
Twilio provides programmable SMS, voice and OTP verification across 180+ countries, which makes it the natural choice when your user base extends beyond India or when you need voice as a channel rather than text alone.
Voice matters more than teams expect. When SMS delivery degrades — and it does, particularly across carriers and borders — a voice OTP fallback is often the difference between a customer completing login and abandoning it. Our integration wires SMS, voice and Verify into a single send interface with a fallback chain, so channel failure triggers escalation automatically instead of surfacing as a support ticket about codes that never arrived.

Twilio API integration — FAQs
Can Twilio be a fallback for an Indian SMS provider?
Yes, and that is a common configuration — a domestic provider for Indian numbers with Twilio handling international traffic and voice fallback.
Do we need our own Twilio account?
Yes. The connector runs against your account and pricing; we do not resell the underlying messaging.
How are delivery receipts handled?
Receipts are normalised into the same event model as the other messaging providers, so your alerting logic has one contract regardless of channel.
