Live-ready OTP infrastructure

Never lose an OTP because a provider failed.

OTP Middleware sits between your app and your SMS, WhatsApp, and email providers — routing, retrying, and falling back automatically so codes always arrive.

Features

The smart layer between your app and OTP providers

Integrate once and let OTP Middleware handle routing, retry logic, fallbacks, and monitoring.

Routing

Multi-channel delivery

Send OTPs over SMS, WhatsApp, or email with priorities per tenant and per country.

Failover

Automatic fallback

When your primary provider times out or fails, fallback routes trigger automatically.

Mobile app

Device-based backup sending

Operators get a push, tap once, and their phone sends the OTP by SIM, WhatsApp, or email.

Tenants

Multi-tenant by design

Onboard and isolate multiple businesses or environments with their own provider configs.

Observability

Delivery insights

Log requests and responses to see which providers fail and where users struggle.

Integrations

Simple REST API

Minimal endpoints, token-based auth, and clear JSON responses for quick integration.

Ship OTPs with confidence — even on your worst traffic days.

Downtime happens. Provider outages happen. OTP Middleware catches those failures and keeps your users logging in, signing up, and confirming payments without friction.
