Usage

To use:

  • simply require module
  • create connector
  • call payWithBLIK() method or payWithGooglePay() method

Create a connector

const eServiceModule = require('eservice-pl');

// configure options
// these is the minimal set of configuration options, you MUST provide your merchant data agreed with eService
// and application details
const ESERVICE_OPTIONS = {
    // for production usage change URLs below to your production eservice endpoint - by default
    // test environment is used
    //apiBaseURL: 'https://apiuat.test.secure.eservice.com.pl',
    //formBaseURL: 'https://cashierui-apiuat.test.secure.eservice.com.pl',
    merchantId: '--your merchant id--',
    password: '--your password--',
    currency: 'PLN', //iso currency code
    country: 'PL', // iso country code
    allowOriginUrl: '--your domain--',
    merchantNotificationUrl: '--your notification url (where status will be sent in async way)--'
}

eServiceModule.configure(ESERVICE_OPTIONS);
// from now on you can request payments

Invoke BLIK payments

// make a BLIK payment

// this is the BLIK code that is entered by the customer
var BLIKCode = 712898;

var customerEmail = 'test@test.pl';
var customerExternalId = 'myCRMId1';
var amount = '1.00';
var paymentDescription = 'Your product';
var transactionId = 'your internal transaction id - will be used in status async notification';


eServiceModule.payWithBLIKSingleItem(amount, BLIKCode, customerEmail, customerExternalId, paymentDescription, transactionId).then(response=>{
  // here one can check on the response if the payment was a success 
	console.log('There was a valid response', response);
}).catch(error=>{
  // this is called when any business related error has happened (such as unauthorized payment attempt)
	console.log('Failed to handle payment', error);
});
