Backend OTP delivery API

Verify users with codes sent over WhatsApp.

Baghdad OTP is a backend service your application calls to deliver one-time passcodes over WhatsApp. It's an API — not a login screen — focused on a single job: getting authentication codes to your users, reliably.

What it does

Built for one job: delivering passcodes

A focused, backend-only service — no end-user dashboards, no marketing tooling, no clutter.

Delivered over WhatsApp

Codes arrive on an app your users already trust and check daily — higher completion rates, with nothing new to install.

No marketing, ever

Every message is a one-time passcode for verification. We never send promotions, ads, or unsolicited content.

A backend API

Your server calls one endpoint to send a code. There's no login UI to embed.

POST /v1/otp/send

Secure by default

Numbers are used only to deliver codes, stored securely, and never sold or shared with third parties.

Deletion on request

Users can ask us to delete their data at any time.

How to request
How it works

Verification in three steps

Everything happens behind the scenes of your application.

  1. 1

    Your app requests a code

    When a user needs to be verified, your backend calls the Baghdad OTP API with the user's phone number.

  2. 2

    We deliver it over WhatsApp

    Baghdad OTP generates a one-time passcode and sends it straight to the user's WhatsApp.

  3. 3

    The user is verified

    They enter the code in your app, your backend confirms it, and the sign-in or action proceeds.

Our promise

Authentication only. No marketing — not now, not ever.

Baghdad OTP exists to deliver verification codes. We don't run campaigns, send promotions, or sell your data.
