Mafpay web library Angular9 version

Using MAF Pay library will provide the comfort during implementing the payment page, by providing the pre-defined web components that validate and process the user inputs by its own.

MAF Pay payment services allows merchants to accept payments by integrating with the payment APIs in the Javascript Framework of their choice. It offers:

• Customizable UI components.
• Validations to limit the chances of incorrect data entry.
• An easier API integration process.
• Tokenization service to securely store customer's data.

How to setup it

In your vue project, install the dependencies for payments component:

npm install @mafpay/weblib @mafpay/weblib-angular9 --save

Or if you use yarn

yarn add @mafpay/weblib @mafpay/weblib-angular9

To configure the minimum styles add the following styles into angular.json

"styles": [
  "./node_modules/@mafpay/weblib/dist/mafpay/mafpay.css"
],

Include MAF Pay components by calling defineCustomElements() in your main JS file:

import { defineCustomElements } from "@mafpay/weblib";

defineCustomElements();

Next step is to import MAF Pay in an Angular module, as shown in the code snippet below:

import { MafpayWeblibModule } from '@mafpay/weblib-angular9';

@NgModule({
  imports: [
    MafpayWeblibModule
  ],
})
export class YourModule { }

Create Card Payment Form

This payment form consists of six customizable UI components:

• <mafpay-card-number></mafpay-card-number>
• <mafpay-card-holder-name></mafpay-card-holder-name>
• <mafpay-card-expiry></mafpay-card-expiry>
• <mafpay-card-cvc></mafpay-card-cvc>
• <mafpay-remember-card></mafpay-remember-card>
• <mafpay-card-submit></mafpay-card-submit>

that can be used as shown in the following snippet of code

import { Component } from '@angular/core';

@Component({
  selector: 'app-your-component',
  template: `
    <form method="POST" action="https://payment.sandbox.mafpayments.com/tokenize" noValidate> 

      <div className="payment-form"> 

        <input type="hidden" name="merchantId" value="Your Marchent ID"/> 
        <input type="hidden" name="apiKey" value="Your API Key"/> 
        <input type="hidden" name="command" value="tokenize"/> 

        <mafpay-card-holder-name></mafpay-card-holder-name>
        <mafpay-card-number></mafpay-card-number>
        <mafpay-card-expiry></mafpay-card-expiry>
        <mafpay-card-cvc masked="false"></mafpay-card-cvc>
        <mafpay-card-submit></mafpay-card-submit>

      </div> 

    </form>
  `,
})
export class YourComponent {

}

To create the card payment form and apply the required UI customization you need to follow the steps in our integration guide: "https://apidocs.mafpayments.com/online/#web-library-create-card-payment-form"

And here is an example below, to give you an idea of how to use events with Angular:

import { Component, HostListener } from '@angular/core';

@Component({
  selector: 'app-your-component',
  template: `
    <mafpay-card-number></mafpay-card-number>
  `,
})
export class YourComponent {

  @HostListener('cardNumberStatus', ['$event'])
  cardNumberStatusEventHandler(event: any) {    
    console.log(event.detail);
  }

}

And here is an example below, to give you an idea of how to use methods with Angular:

import {Component, ElementRef, ViewChild} from '@angular/core';

@Component({
  selector: 'app-your-component',
  template: `
    <mafpay-card-number #mafpayCardNumberRef></mafpay-card-number>
    <button (click)="resetHandler()">Reset</button>
  `,
})
export class YourComponent {

  @ViewChild('mafpayCardNumberRef', { read: ElementRef }) mafpayCardNumberRef: ElementRef;

  resetHandler() {
    this.mafpayCardNumberRef.nativeElement.resetField();
  }

}

Create Card Form Using Wrapper Component(single component):

You can use mafpay-card-form to create the card form that comes with our default UI design, this component will build the entire credit/debit card form for you, for more details please follow the steps in our integration guide:

You can listen to all events related to the card form component using on() method, the method takes two parameters: event name and callback function(the function will be called once the event has been emitted).

To reset all fields inside card form, you can use resetFields() method.

The example below demonstrates how to use mafpay-card-form component with Angular9:

@Component({
  selector: 'app-root',
  template: `
    <mafpay-card-form #mafpayCardForm [config]="config"></mafpay-card-form>
    <button (click)="resetFieldsHandler()">Reset</button>
  `,
})
export class AppComponent {
  @ViewChild('mafpayCardForm', {static: true }) private mafpayCardForm
  title = 'weblib-angular-sample';
  config = {
    tokenizev2: true,
    verifyCard: 'threeds',
    merchantId: '<YOUR MERCHIENT ID>',
    apiKey: '<YOUR API KEY>',
    command: 'tokenize',
    cardNumberPlaceHolder: 'Card Number',
    cardCvcPlaceHolder: 'CVC',
    cardCvcMasked: true,
    cardCvcTooltip: true,
    cardExpiryPlaceHolder: 'MM/YY',
    cardHolderNamePlaceHolder: 'Holder Name',
    cardDefaultPlaceHolder: 'Default Card',
    rememberCardPlaceHolder: 'Remember me?',
    isHolderNameRequired: true,
    submitLabel: 'Submit'
  }
  
  ngOnInit() {
    this.mafpayCardForm.on('tokenizationComplete', this.tokenizationComplete);
    this.mafpayCardForm.on('cardHolderNameStatus', this.cardHolderNameStatus);
    this.mafpayCardForm.on('cardExpiryStatus', this.cardExpiryStatus);
    this.mafpayCardForm.on('cardCvcStatus', this.cardCvcStatus);
    this.mafpayCardForm.on('cardNumberStatus', this.cardCvcStatus);
  }

  resetFieldsHandler() {
    this.mafpayCardForm.resetFields()
  }

  tokenizationComplete(event) {
    console.log('tokenizationComplete', event)
  }

  cardHolderNameStatus(event) {
    console.log('cardHolderNameStatus', event)
  }

  cardExpiryStatus(event) {
    console.log('cardExpiryStatus', event)
  }
