Why OTP Delivery
Reliability Matters

A failed OTP is a failed login, a lost transaction, and a frustrated customer. Ritorica's Verify OTP eliminates single-channel risk by routing each code through the fastest available path — so users verify successfully on the first attempt, every time.

Sub-3-Second Delivery

Most OTPs arrive in under 3 seconds. Users verify without waiting — reducing drop-off at your most critical conversion point.

Automatic Channel Fallback

If SMS is slow or a user has no WhatsApp, Ritorica instantly switches to the next channel. You set the priority order — we handle the routing.

Fraud-Resistant by Design

Short expiry windows, one-time use codes, and delivery-confirmation webhooks make interception and replay attacks effectively impossible.

Real-Time Delivery Reports

Know exactly which channel delivered, at what timestamp, with what status. Full audit trail per OTP for compliance and debugging.

One API. All Channels.

A single HTTP POST sends the OTP across all configured channels. No vendor management per channel, no complex routing logic in your codebase.

Global Coverage

Reach users in 190+ countries. Ritorica's direct operator agreements and messaging platform partnerships ensure delivery where others fail.

SMS

Universal reach — every mobile phone, no app or internet required. The definitive fallback channel.

99.9% reach

98% open rate. Rich message with branded sender. Preferred channel for markets with high WhatsApp adoption.

98% open rate

Privacy-first delivery preferred in Eastern Europe and the Middle East. Fast, silent, and bot-delivered.

Privacy-first

Voice Code

An automated call reads the OTP aloud. Works without internet and for users who struggle with SMS — the ultimate accessibility fallback.

Max accessibility

Your App Triggers the API

Send a single POST request to Ritorica's API with the recipient's phone number and your preferred channel order. Ritorica generates or accepts your OTP code and handles the rest.

Ritorica Routes to the Best Channel

The OTP is dispatched to Channel 1 (e.g., WhatsApp). If not delivered within your configured timeout, it automatically falls back to Channel 2, then Channel 3 — until confirmed delivered.

Fallback in <30s per channel

Delivery Confirmed — You're Notified

Ritorica fires a webhook to your endpoint with the delivery status, channel used, and timestamp. Your app verifies the code the user enters and grants access.

Configurable Expiry

Set OTP validity windows from 30 seconds to 30 minutes. Short windows reduce attack surface; longer windows improve user experience for your use case.

Smart Cascade Routing

Define your channel priority per user segment, country, or time of day. Ritorica executes the cascade automatically — no code changes required when you update the rules.

Delivery Webhooks

Real-time push notifications to your server on every status change — sent, delivered, failed, expired. Build accurate retry and fallback logic on your side.

Rate Limiting & Anti-Abuse

Built-in per-number rate limits prevent OTP bombing. Configure max attempts per hour, per day, and per session — with automatic blocking of suspicious patterns.

Analytics Dashboard

Track delivery rates, channel performance, average delivery time, and conversion rates per OTP flow. Identify which channels perform best for your user base.

190+ Country Coverage

Direct operator agreements and tier-1 routing ensure OTPs reach users in emerging markets, high-SMS-cost regions, and restricted territories where generic providers fail.
