Marupay SDK

The Marupay SDK is a npm library that provides an easy-to-use interface for integrating with the multiple payment systems.

This SDK offers

• Edahab API
• Waafi API

Installation

To use the Marupay SDK in your project, you can install it using npm:

npm install marupay

Usage

To get started, import the necessary modules and configure the SDK with your credentials. The following example demonstrates how to set up the SDK for both eDahab and Waafi:

import { config } from "dotenv";
import express from "express";
import { HandlerName, ConfigObject, getPaymentHandler, Currency } from "marupay";
import { env } from "process";

// Load environment variables from a .env file
config();

const app = express();
const port = 3002;

app.use(express.urlencoded({ extended: true }));

// Configuration for different payment handlers (e.g., edahab, waafi)
const paymentConfig: ConfigObject = {
  edahab: {
    apiKey: env.DAHAB_API_KEY!,
    secretKey: env.DAHAB_SECRET_KEY!,
    merchantId: env.DAHAB_AGENT_CODE!,
  },
  waafi: {
    apiKey: env.WAAFI_API_KEY!,
    secretKey: env.WAAFI_API_USER_ID!,
    merchantId: env.WAAFI_MERCHANT_KEY!,
  },
};

// Choose a payment handler
const chosenHandler: HandlerName = "edahab";

app.get("/purchase", async (req, res) => {
  try {
    // Get the payment handler based on the chosen handler
    const handler = getPaymentHandler(chosenHandler)(paymentConfig[chosenHandler]!);

    // Make a purchase request
    const paymentInfo = await handler.purchase({
      accountNumber: "+2526512312341", // must start with `+` followed by country code
      amount: 500,
      currency: Currency.SLSH,
      description: "Test purchase",
      // for web handlers, you can optionally provide a return URL
      returnUrl: "https://example.com/return",
    });

    res.send(paymentInfo);
  } catch (e) {
    console.log(e);
    res.status(500).send("Internal Server Error");
  }
});

app.get("/credit", async (req, res) => {
  try {
    // Get the payment handler based on the chosen handler
    const handler = getPaymentHandler(chosenHandler)(paymentConfig[chosenHandler]!);

    // Credit an account
    const paymentInfo = await handler.credit({
      accountNumber: "+2526512312341", // must start with `+` followed by country code
      amount: 1000,
      currency: Currency.SLSH,
      description: "Test credit",
    });

    res.send(paymentInfo);
  } catch (e) {
    console.log(e);
    res.status(500).send("Internal Server Error");
  }
});

app.listen(port, () => {
  console.log(`Server is listening at http://localhost:${port}`);
});

Responses

The credit and purchase methods both returns a PaymentInfo object. It'll return these details:

• transactionId: This identifier is obtained from the vendor's transaction ID. It uniquely identifies the transaction in the vendor's system.

• paymentStatus: The payment status is also retrieved from the vendor's response. It indicates the current status of the payment transaction in the vendor's system.

• referenceId: The reference ID is specific to Marupay and is provided in Marupay's response. It serves as a unique identifier for the transaction within Marupay's system.

• raw: This will return unfiltered response details from the vendor.

Examples

The provided examples demonstrate how to use the Marupay SDK for both purchase and credit transactions with eDahab and Waafi payment handlers. Customize the route handlers according to your application's needs.
