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.
Most OTPs arrive in under 3 seconds. Users verify without waiting — reducing drop-off at your most critical conversion point.
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.
Short expiry windows, one-time use codes, and delivery-confirmation webhooks make interception and replay attacks effectively impossible.
Know exactly which channel delivered, at what timestamp, with what status. Full audit trail per OTP for compliance and debugging.
A single HTTP POST sends the OTP across all configured channels. No vendor management per channel, no complex routing logic in your codebase.
Reach users in 190+ countries. Ritorica's direct operator agreements and messaging platform partnerships ensure delivery where others fail.
Ritorica routes each OTP through the optimal channel automatically — or you control the priority order via a simple config.

Max accessibilityFrom your server to your user's screen — in three steps and under 3 seconds.
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.
~10ms API responseThe 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 channelRitorica 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.
Webhook in <1s of deliveryEvery feature in Ritorica Verify OTP is designed around one requirement: the OTP reaches the right person, on the first attempt, without compromise.
Set OTP validity windows from 30 seconds to 30 minutes. Short windows reduce attack surface; longer windows improve user experience for your use case.
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.
Real-time push notifications to your server on every status change — sent, delivered, failed, expired. Build accurate retry and fallback logic on your side.
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.
Track delivery rates, channel performance, average delivery time, and conversion rates per OTP flow. Identify which channels perform best for your user base.
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.
Any product with a login, transaction, or account action relies on OTP. Here's how industries use it.
Connect via REST API, set your channel order, and send your first verified OTP — all in one session. Your account manager handles the rest.
