Basic Implementation for 2Pay.js Payments Solution

Overview

Set up the 2Pay.js drop-in payments client to accept payments on your website.

Collecting payments consists of creating a payment form, tokenizing sensitive card information, and using that token to create a charge.

Use case

1. Create a form with id="payment-form":

<form type="post" id="payment-form">
  <div class="form-group">
    <label for="name" class="label control-label">Name</label>
    <input type="text" id="name" class="field form-control">
  </div>
  <button class="btn btn-primary" type="submit">Generate token</button>
</form>

2. Inside the form add an element with id="card-element". The form should now look like this:

<form type="post" id="payment-form">
  <div class="form-group">
    <label for="name" class="label control-label">Name</label>
    <input type="text" id="name" class="field form-control">
  </div>

  <div id="card-element">
    <!-- A TCO IFRAME will be inserted here. -->
  </div>

  <button class="btn btn-primary" type="submit">Generate token</button>
</form>

3. Include the 2Pay.js drop-in payment client javascript:

<script type="text/javascript" src="https://2pay-js.2checkout.com/v1/2pay.js"></script>

4. Insert the following configuration JavaScript to add the card component and generate token request: 

window.addEventListener('load', function() {
  // Initialize the JS Payments SDK client.
  let jsPaymentClient = new  TwoPayClient('RDGM');
  
  // Create the component that will hold the card fields.
  let component = jsPaymentClient.components.create('card');
  
  // Mount the card fields component in the desired HTML tag. This is where the iframe will be located.
  component.mount('#card-element');

  // Handle form submission.
  document.getElementById('payment-form').addEventListener('submit', (event) => {
    event.preventDefault();
    
    // Extract the Name field value
    const billingDetails = {
      name: document.querySelector('#name').value
    };

    // Call the generate method using the component as the first parameter
    // and the billing details as the second one
    jsPaymentClient.tokens.generate(component, billingDetails).then((response) => {
      console.log(response.token);
    }).catch((error) => {
      console.error(error);
    });
  });
});

5. Place the order using the generated token.
