What is OTP & Verification SMS?

OTP SMS is a high-priority messaging service designed to deliver time-sensitive verification codes — one-time passwords, PINs and auth tokens — to users in seconds. Unlike standard bulk SMS, OTP routes bypass promotional queues and use direct carrier connections to guarantee near-instant delivery. This makes OTP SMS the standard method for two-factor authentication (2FA) and transaction verification.

What you get

Priority Routing

OTP messages bypass standard queues for delivery in under 5 seconds.

Expiry & Retry Logic

Set code expiry windows and automatic retry if the first attempt fails.

API Integration

Simple REST API with SDKs for all major languages and frameworks.

Failover to Voice OTP

If SMS delivery fails, the system can escalate to a voice OTP call automatically.

Global Reach

Send OTP to numbers in 180+ countries with local routing for best delivery.

Delivery Receipts

Confirm delivery at the carrier level for audit and compliance requirements.

How businesses use it

SaaS PlatformsTwo-factor authentication for login and sensitive account changes.
E-commercePayment confirmation codes, address verification and order authentication.
Banking & FintechTransaction authorisation codes and account recovery verification.
Healthcare PortalsPatient portal login, prescription authorisation and record access.

How to get started

01

Integrate

Add the OTP API to your app with a single endpoint — 15-minute integration.

02

Generate

Your system triggers the OTP request; we generate and deliver the code.

03

Verify

The user enters the code; your system confirms against the API response.

Clear answers.
Before we connect.

How is the API different from the WhatsApp Business app?

The Business Platform provides APIs for integrations and scaled messaging workflows. A shared inbox, automation and CRM connections are built or provided through the selected solution.

Do we need templates for every reply?

Replies to a user message can be sent without a template within the 24-hour customer service window. Outside that window, the Platform requires approved message templates. Recipient permission and other policy requirements still apply.

Is a verification badge included?

No. Business verification and verification badges are separate processes. Any badge or account eligibility is controlled by Meta and is not guaranteed by this service.

Can you connect our CRM or existing inbox?

We review supported APIs, account features and available access. The integration scope is agreed around the tools your team uses.

What does it cost?

Pricing depends on the implementation, selected provider or software, usage and applicable Meta charges. We scope these for your setup; no fixed platform price is claimed in this preview.

Will this demonstration send a WhatsApp message?

No. The message workspace, inbox and enquiry form are local previews. Live sending requires a configured account, the appropriate permissions and an agreed implementation.
