# Introduction

> Lyel Pay — the payment infrastructure built for African businesses.

## What is Lyel Pay?

Lyel Pay is a payment platform that lets your users **pay, receive, and manage money** from a single place. For developers, it means one API and a set of SDKs to:

* Accept payments from mobile money wallets (MTN MoMo, Orange Money, Airtel Money, M-Pesa, and more)
* Send transfers between users
* Handle cash-in and cash-out
* Issue billing and invoices
* Track all transactions in real time via a backoffice

Lyel Pay operates in **XAF** (Central Africa / CEMAC zone) and **XOF** (West Africa / UEMOA zone).

***

## How it works

Lyel Pay uses a **four-step transaction flow** for all operations:

<Steps>
  <Step title="Create an Intention">
    Declare the operation you want to execute (payment, deposit, withdrawal, or transfer) with an amount and the parties involved.
  </Step>

  <Step title="Send OTP">
    Trigger an SMS or email OTP to the user who needs to authorize the operation.
  </Step>

  <Step title="Verify OTP">
    The user enters the code they received. Lyel Pay validates it and issues a short-lived authorization token.
  </Step>

  <Step title="Execute">
    Call `charge()` (browser SDK) or use the gateway endpoint (server) to finalize the transaction.
  </Step>
</Steps>
