Installation

npm install flutterwave-rn-pos

or

yarn add flutterwave-rn-pos

Usage

Import the methods you want to use from the package in your JavaScript/TypeScript code:

import {
  performKeyExchange,
  performTransaction,
  printReceipt,
  performReprintAndEOD,
  viewTransactionHistory,
} from 'flutterwave-rn-pos';

// key exchange

// ...

const result = await performTransaction(
  200,
  false,
  ['CARD', 'TRANSFER'],
  '3.2.1'
);

Key Exchange

A key exchange is done to get the terminal parameters. This should be performed upon launch of your application before you start making transactions. To do this, follow the steps below:

const ParameterResponse = await performKeyExchange(
  'Flutterwave',
  'https://flutterwave.com/waveLogo.png'
);

The merchantName represents a unique identifier for your business and customLogoUrl is an optional parameter for your custom logo.

Transactions

To perform a transaction, you'll need the following parameters

Amount shouldPrint transactionTypes and AppVersion

🚨 Note: The possible values for Transaction Types include: ‘CARD’, ‘TRANSFER’, ‘USSD’, ‘MOMO’, and ‘QR’.

const transactionResponse = await performTransaction(
  200, // Amount
  false, // Should Print
  ['CARD', 'TRANSFER'], // Transaction Types
  '3.2.1' // App Version
);

Once the function is launched, the POS will take over and complete the card processing flow. When this is completed, the transaction details are returned as a json string.

Printing

To print a receipt, design your receipt such that each line represents an instance of the PrintField object. Add each line as a print field to a array. To do this, follow the steps below:

const printResponse = await printReceipt([
  {
    header: 'Flutterwave',
    alignment: 'center',
    textSize: 40,
    bold: true,
  },
  {
    header: 'RRN',
    body: '1234567890',
    bold: false,
    alignment: 'left',
    textSize: 30,
  },
  {
    header: 'Amount',
    body: '100.0',
    bold: true,
    alignment: 'center',
    textSize: 30,
  },
]);

When the terminal completes the printing process, A response is returned as a callback contain a json with the same pattern as the TransactionResponse but with the data field set to null.

Reprint And EOD

To reprint transactions and perform end of day actions, follow the steps below:

const reprint = await performReprintAndEOD();

The POS will take over and complete the process once the function is launched.

TRANSACTION HISTORY

To view all transactions that have been made on the POS device, follow the steps below:

const launchHistory = await viewTransactionHistory();

The POS will take over and complete the process once the function is launched.
