Paystack

A NodeJS Wrapper for Paystack

Overview

This project provides an easy-to-use object-oriented API to access endpoints delineated at https://developers.paystack.co/reference

Getting Started

Install from the NPM Registry

    $ npm i --save paystack-node

Usage

let PayStack = require('paystack-node')

let APIKEY = 'sk_live_2hWyQ6HW73jS8p1IkXmSWOlE4y9Inhgyd6g5f2R7'
const environment = process.env.NODE_ENV

const paystack = new PayStack(APIKEY, environment)

const feesCalculator = new PayStack.Fees();
const feeCharge = feesCalculator.calculateFor(250000) // 2,500 Naira

/* 
  NOTE: All fields/params that require dates should be set to
  instances of the `Date()` constructor as they will
  eventually be turned into the ISO 8601 format (String)
  using `toJSON()` method for date instances/objects
*/

const promise_0 = paystack.getSettlements({
  from:new Date("2017-02-09"), 
  to:new Date()
})

promise_0.then(function(response){
  var data = response.body.data;
}).catch(function (error){
  // deal with error
})

// listBanks

try {
  let { body: { status, message, data } } =  await paystack.listBanks({
    currency: 'NGN'
  });

  if(status === false){
    throw new Error(message);
  }
}catch(ex){
  console.error(ex.message);
}

// addPageProduct

const promise1 = paystack.addPageProduct({
  id: '0826739',
  products: [473, 292]
})

promise1.then(function(response){
   // Error Handling
   if(response.body.status === false){
     console.error(response.body.message);
   }
   var data = response.body.data;
}).catch(function (error) {
  // deal with error
})

// getCustomer

const promise2 = paystack.getCustomer({
  customer_id:'CUS_e24m6SqA6g3Jk889o21'
})

promise2.then(function(response){
  var data = response.body
  
}).catch(function(error){
  // deal with error
})

// createCustomer

const promise3 = paystack.createCustomer({
  email:'[email protected]',
  first_name:'Malik',
  last_name:'Onyemah',
  phone:'+2347135548369'
})

promise3.then(function(response){
  return response.body
}).then( body => {
  return res.status(200).json({id:body.data.id})
})

// setRiskActionOnCustomer

const promise4 = paystack.setRiskActionOnCustomer({
  risk_action:'deny',
  customer_id:'CUS_e24m6SqA6g3Jk889o21'
})

promise4.then(function (response){
   const result = response.body
}).catch(function (error){
  // deal with error
})

// createPage

const promise5 = paystack.createPage({
  name:'DoorPost Pay',
  description:'This is payment for every ',
  amount:300000, // Amount in kobo
  slug:'5nApBwZkvR',
  redirect_url:'https://www.localhoster.com/pay/callback',
  custom_fields: ['phone_number', 'age']
})

promise5.then(function (response){
 console.log(response.body);
}).catch(function (error){
  // deal with error
})

// initializeTransaction

const promise6 = paystack.initializeTransaction({
  reference: "7PVGX8MEk85tgeEpVDtD",
  amount: 500000, // 5,000 Naira (remember you have to pass amount in kobo)
  email: "[email protected]",
  subaccount: "ACCT_8f4s1eq7ml6rlzj"
})

promise6.then(function (response){
  console.log(response.body);
}).catch(function (error){
  // deal with error
})

// verifyTransaction

const promise7 = paystack.verifyTransaction({
  reference: "7PVGX8MEk85tgeEpVDtD"
})

promise7.then(function (response){
 console.log(response.body);
}).catch(function (error){
  // deal with error
})

// listInvoices

const promise8 = paystack.listInvoices({
  customer: "CUS_je02lbimlqixzax",
  status: "pending",
  paid: false,
  currency: "NGN"
})

promise8.then(function (response){
 console.log(response.body);
}).catch(function (error){
  // deal with error
})

app.use(async function verifications(req, res, next){
    let responseBVN = await paystack.resolveBVN({
      bvn:req.body.bvn //'22283643840404'
    })

    let responseAcctNum = await paystack.resolveAccountNumber({
      account_number:req.body.acc_num, // '0004644649'
      bank_code:req.body.bank_code // '075'
    })

    next()
})

Mocking the Instance (for Unit/Integration Tests)

Setting up mocks for testing with the paystack instance is now as easy as fliping a switch like so:

let PayStack = require('paystack-node')

let APIKEY = 'sk_live_2hWyQ6HW73jS8p1IkXmSWOlE4y9Inhgyd6g5f2R7'
const environment = process.env.NODE_ENV

const paystack = new PayStack(APIKEY, environment)

// call the real API methods
const { body } = paystack.chargeCard({
  card:{
    number: '5399837841116788', // mastercard
    cvv: '324',
    expiry_year: '2024',
    expiry_month: '08'
  },
  email: '[email protected]',
  amount: 15600000 // 156,000 Naira in kobo
})

// mocking call made on the constructor
// start mocking
PayStack.engageMock()

// call the mock API methods
const { body } = await paystack.chargeBank({
  bank: {
    code: "050", // Eco Bank
    account_number: "0000000000"
  },
  email: '[email protected]',
  amount: 1850000 // 18,500 Naira in kobo
})

// replace mocked methods (! don't use arrow functions !)
PayStack.mockMacro(
  'getCustomers', 
  async function getCustomers (reqPayload = {}) {
    // validation for (reqPayload) is already taken care of!

    // @TODO: optionally, connect to a in-memory db (redis) for mocking purposes

    // return mocked response object
    return { status: 200, body: { status: "success", data: reqPayload } };
})

const { body } = await paystack.getCustomers({
  customer_id:'CUS_e24m6SqA6g3Jk889o21'
})

// stop mocking
// mocking call made on the constructor
PayStack.disengageMock()
