creditguard

#Creditguard node.js

A simple wrapper to creditguard api

Usage

Installation

npm install creditguard

Setting up

var creditguard = require('creditguard');

var env = {
  user: 'username',
  password: 'password',
  server: 'https://cguat2.creditguard.co.il',
  terminal: '1234567',
  mid: '531',
  // optional callback addresses when using cg redirect api
  // when left empty, cg will use the predefined terminal value
  success_url: 'localhost/payment/proceed?',
  error_url: 'localhost/payment/rejected?',
  cancel_url: 'localhost/payment/rejected?'
};

var options = {
  verbose: true, // prints more logs, default to false
  cleanup: true // remove empty fields from result, default to false
};

var cg = creditguard(env, options);

Charging

creditguard-node follows cg xml-api (see their docs) parameters names. For example, if their api expects the following xml :

<ashrait>
   <request>
      <command>doDeal</command>
      <requestId/>
      <version>1001</version>
      <language>Eng</language>
      <mayBeDuplicate>0</mayBeDuplicate>
      <doDeal>
         <terminalNumber>0962XXX</terminalNumber>
         <cardNo>458045XXXXXX4580</cardNo>
         <cardExpiration>1212</cardExpiration>
         <creditType>RegularCredit</creditType>
         <currency>USD</currency>
         <transactionCode>Phone</transactionCode>
         <transactionType>Debit</transactionType>
         <total>10010</total>
         <validation>AutoComm</validation>
         <user>567890</user>
      </doDeal>
   </request>
</ashrait>

Then the proper use would be :

// basically create an object with everything you want to put under 'doDeal' element
// (no need to inset terminal number or any other value from 'env')
var charge = {
  cardNo: '458045XXXXXX4580',
  cardExpiration: '1212'
  creditType: 'RegularCredit',
  currency: 'USD',
  transactionCode: 'Phone',
  transactionType: 'Debit',
  total: 10010,
  validation: 'AutoComm'
  user: '567890'
};

cg.call(charge, function(err, res) {
  if (err) {
    console.error(err);
    console.error(res);
  } else {
    console.log(res);
  }
});

Customer data

If you are using the xml api to get a redirect page and you want to use customerData fields to pass some data into that page, you can do it simply by attaching it to charge object:

charge.customerData = {
  userData1: 'userData1',
  userData3: 'userData3',
  ...
}

Invoices

If your terminal supports invoices you can easily attach invoice to the call again, by attaching it to the charge object:

// check out cg invoice documentation for complete list of properties
charge.invoice = {
  invoiceCreationMethod: 'wait',
  invoiceSubject: 'Subject',
  invoiceItemQuantity: 1,
  invoiceItemPrice: 10010,
  companyInfo: 'Vandelay Industries',
  mailTo '[e-mail]',
  ...
}

Response

creditguard-node takes cg xml response and converts it to a javascript object so there's no need for you to parse any xml. It also verify that the transaction result code is 000 (OK) and if not, throws an informative error that you can catch.

TODO

• Add mock test server that emulates cg server to remove dependency in cg real servers.
• Add more tests.
• Add more apis for common operations like charge, capture and redirect.
