paypal-nvp-api

Node.js wrapper for the Paypal Name-Value Pair — NVP

Usage

Import module and init an instance with given config:

const Paypal = require('paypal-nvp-api');


const config = {
  mode: 'sandbox', // or 'live'
  username: 'someone.itravellocal.com',
  password: 'DYKNJZZE42ASN699',
  signature: 'A0aEilikhBmwfK.NlduDjCbsdgXdA8VDPMDksDhGsHmLQECu80Qtru09'
}

const paypal = Paypal(config);

Build query and send to Paypal server:

paypal.request('GetBalance', {}).then((result) => {
  console.log(result);
}).catch((err) => {
  console.trace(err);
});

The 'result' looks like this:

{
  L_AMT0: '71084.27',
  L_CURRENCYCODE0: 'USD',
  TIMESTAMP: '2016-03-18T09:48:16Z',
  CORRELATIONID: 'e3de6137ce65c',
  ACK: 'Success',
  VERSION: '124',
  BUILD: '18316154'
}

Another example with "SetExpressCheckout" operation:

const query = {
  'PAYMENTREQUEST_0_AMT': '20.00',
  'PAYMENTREQUEST_0_CURRENCYCODE': 'USD',
  'PAYMENTREQUEST_0_PAYMENTACTION': 'Sale',
  'RETURNURL': 'http://google.com/test/onreturn',
  'CANCELURL': 'http://google.com/test/oncancel'
};

paypal.request('SetExpressCheckout', query).then((result) => {
  console.log(result);
}).catch((err) => {
  console.trace(err);
});

In this case, it returns something like this:

{
  TOKEN: 'EC-5Y171147E8077933D',
  TIMESTAMP: '2016-03-18T09:58:38Z',
  CORRELATIONID: 'e8289e4235624',
  ACK: 'Success',
  VERSION: '124',
  BUILD: '18316154'
}
