Node Library

Merchant Service API Library

Merchant Services is a NodeJS module that helps you make API calls when processing Paga Transactions.

1. Installation

Use the package manager npm to install paga-merchant.

Sample Code

npm install paga-merchant

2. Usage

To use PagaMerchantClient, you would need to import it

Sample Code

const PagaMerchant = require('paga-merchant');

To Initialize the module, you use a builder to set all required values

Sample Code

var pagaMerchantClient = PagaMerchant.Builder()
      .setPrincipal("<Paga_Merchant_Public_ID>")
      .setCredential("<Paga_Merchant_Credentials>")
      .setApiKey("<Merchant_Api_Key>")
      .setIsTest(true)
      .build();

As shown above, you set the principal and credential given to you by Paga, If you pass true as the value for setIsTest(), the library will use the test url as the base for all calls. Otherwise setting it to false will use the live url value you pass as the base.
