Mafpay web library React JS 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-react --save

Or if you use yarn

yarn add @mafpay/weblib @mafpay/weblib-react

To configure the minimum styles add the following styles to your main JS file:

import "../node_modules/@mafpay/weblib/dist/mafpay/mafpay.css"

or import it inside your main CSS file:

@import url("../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();

Create Card Payment Form

This payment form consists of six customizable UI components:

• <MafpayCardNumber />
• <MafpayCardHolderName />
• <MafpayCardExpiry />
• <MafpayCardCvc />
• <MafpayRememberCard />
• <MafpayCardSubmit />

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

import React from "react";
import { MafpayCardHolderName, MafpayCardNumber, MafpayCardExpiry, MafpayCardCvc, MafpayCardSubmit } from "@mafpay/weblib-react";

const App = () => {
  return (
    <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"/> 

        <MafpayCardHolderName />
        <MafpayCardNumber />
        <MafpayCardExpiry />
        <MafpayCardCvc masked="false" />
        <MafpayCardSubmit />

      </div> 

    </form>
  );
}

export default App;

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 React JS:

import React from "react";
import { MafpayCardNumber } from "@mafpay/weblib-react";

const App = () => {

  const onCardNumberStatusHandler = (event) => {
    console.log(event.detail);
  }

  return (
    <MafpayCardNumber onCardNumberStatus={(event) => onCardNumberStatusHandler(event)} />
  );

}

export default App;

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

import React from "react";
import { MafpayCardNumber } from "@mafpay/weblib-react";

const App = () => {

    const mafpayCardNumberRef = React.useRef(null);

    const resetHandler = () => {
        mafpayCardNumberRef.current.resetField();
    }

    return (
        <div>
            <MafpayCardNumber ref={mafpayCardNumberRef} />
            <button onClick={() => resetHandler()}>Reset</button>
        </div>
    );

}

export default App;

Create Card Form Using Wrapper Component(single component):

You can use MafpayCardForm 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 MafpayCardForm component with react:

import React from "react";
import { MafpayCardForm } from "@mafpay/weblib-react";

const App = () => {
    const mafpayCardForm = React.useRef(null);
    const [config, setConfig] = React.useState({
       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'
    });
    
    useEffect(() => {
      mafpayCardForm.current.on('tokenizationComplete', tokenizationComplete);
      mafpayCardForm.current.on('cardHolderNameStatus', cardHolderNameStatus);
      mafpayCardForm.current.on('cardExpiryStatus', cardExpiryStatus);
      mafpayCardForm.current.on('cardCvcStatus', cardCvcStatus);
      mafpayCardForm.current.on('cardNumberStatus', cardNumberStatus);
    }, []);

    function resetFieldsHandler() {
      mafpayCardForm.current.resetFields()
    }

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

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

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

    function cardCvcStatus(event) {
     console.log('cardCvcStatus', event)
    }

    function cardNumberStatus(event) {
     console.log('cardNumberStatus', event)
    }

    return (
    <div>
