OTP RESELLER PROGRAM

Create Your Own OTP Platform & Earn

Use Hanu OTP as your backend and launch your own brand. Buy OTP at reseller prices and sell to your clients on your own rates.

1. Create Your Platform

Build your own website, panel or SaaS on top of our OTP APIs. We handle routing, delivery, infrastructure and uptime.

2. Get Special Reseller Pricing

As a reseller, you get lower OTP rates for SMS, WhatsApp and Voice (configured in your account).

Example: If your reseller rate is X and you sell to your client at X+Y, your profit is Y per OTP.

3. Onboard Unlimited Clients

Add as many clients as you want on your own platform and charge them monthly or per OTP as per your plan.

Your clients see only your brand while Hanu OTP works in the background.

How your earning works

  • You pay Hanu OTP at special reseller prices.
  • You decide the selling price for your end customers.
  • Profit per OTP = Client price − Your reseller price.
  • Higher volume from your clients directly increases your monthly income.
  • No need to manage SMS gateways, WhatsApp templates or calling infra.

Simple steps to get started

  1. Sign up on Hanu OTP and complete KYC (if required).
  2. Apply for reseller from the Reseller Program page.
  3. Once approved, your account role will be set to reseller.
  4. Integrate our OTP APIs inside your own panel or website.
  5. Create packages for your clients and start selling under your brand.
