​
Quickstart

Get up and running in three steps:
1

Install the SDK

Install the Fingo Pay TypeScript SDK:
npm add @fingoafrica/fingo-pay
2

Initialize the client

Set up the SDK with your API key:
import { FingoPay } from "@fingoafrica/fingo-pay";

const fingoPay = new FingoPay({
  bearerAuth: process.env.FINGO_API_KEY,
});
Get your API key from the Fingo Pay Dashboard.
3

Create your first charge

Initiate an M-Pesa STK Push payment:
const result = await fingoPay.payments.createMpesaCharge({
  body: {
    merchantTransactionId: "order_12345",
    amount: 150000, // KES 1,500.00 in cents
    phoneNumber: "+254712345678",
    narration: "Order #12345",
  },
});

console.log(result.data.transactionId);
// => "txn_01j7b6f9p5y9h"
The customer receives an STK Push prompt. Final status arrives via webhook.

​
Or use the REST API directly

Prefer to call the API directly? Use cURL or any HTTP client: 
curl -X POST "https://api.fingopay.io/v1/mpesa/charge" \
  -H "Authorization: Bearer sk_test_***" \
  -H "Content-Type: application/json" \
  -d '{
    "phoneNumber": "+254712345678",
    "amount": 150000,
    "merchantTransactionId": "order_12345",
    "narration": "Order #12345"
  }'
