Integration guide

PayPal

PayPal requires you to display the PayPal Button on your Checkout page. This is handled by the payment.js integration.

1. Embed the payment.min.js in your page

<script data-main="payment-js" src="https://gateway.ixopay.com/js/integrated/payment.1.3.min.js"></script>

note

It is important to set the data-main="payment-js" attribute on the script tag.

2. Provide a DIV element on your page for the PayPal button

<div id='paypalButtonDiv'></div>

3. Initialize the payment.js with the following parameters:

ID of the DIV element
Javascript function to handle payment completion
Javascript function to handle error events
Javascript function to handle cancellation events
PayPal options (see below in example, refer to PayPal Documentation for possible options. The 'vault' option is per default set to 'false' if not otherwise specified. Please refer to the PayPal Documentation for the different button options)
Your server endpoint where prepareCall is implemented. It could either be prepare-debit/prepare-preauthorize/prepare-register based on the transaction type

PayPal options

Option	Required	Type	Description
`paypal-btn`	yes	HTMLElement	Container element into which the button will be rendered.
`currency`	yes	string	Currency
`intent`	yes	string	Possible values - capture, authorize. Preauthorize flow requires to send authorize. Otherwise, it should be set to capture.
`createOrderEndpoint`	yes	string	Your server endpoint where prepareX transaction is implemented

`completeHandler`	no	(data) => void	Triggered after successful payment.

`cancelHandler`	no	(data) => void	Triggered if the user canceled the payment process.
`button`	no	object	https://developer.paypal.com/sdk/js/reference/#link-style

<script>
  var paymentJs = new PaymentJs('1.3');

  errorHandler = function (error) {
      // If an error prevents buyer checkout, alert the user that an error has occurred with the buttons using the onError callback
  }

  cancellationHandler = function (data) {
      // When a buyer cancels a payment, they typically return to the parent page.
      // You can instead use the onCancel function to show a cancellation page or return to the shopping cart.
  }

  completeHandler = function (paypalToken) {
      // Captures the funds from the transaction and shows a message that tells the buyer the payment was successful.
      // The method is called after the buyer approves the transaction on the paypal.com website.
      // paypalToken should be passed to the debit request using extraData with the key 'paypalToken'

  }

  var paypalOptions = {
      button: {
          color: gold,
      },
      currency: "EUR",
      intent: "capture" || "authorize", // debit = capture / preauthorize = authorize
      vaultingWithoutPurchase: false // should be set to true if you're doing register call
      vault: false // should be set to true if you would like to vault transaction using PayPal vaulting. for example register / debit + withRegister=true
  };

  var prepareCall = () => {
    // prepare Transaction on your backend
    return fetch('{MY_PREPARE_ENDPOINT}', {
      method: 'POST',
    }).then(function (res) {
      return res.json();
    }).then(function (data) {
      return data.id;
    });
  };

  paymentJs.initPaypal(
    'public-integration-key',
    'paypal-button-div',
    completeHandler,
    errorHandler,
    cancellationHandler,
    paypalOptions,
    prepareCall
  );
</script>

4. You can now call the Transaction API with the extraData.paypalToken set to the paypalToken returned to the completeHandler.

Prepare Transaction

PayPal requires to create order/setup token when the PayPal button is being pressed. That's being handled with prepareDebit/preparePreauthorize/prepareRegister API calls. Therefore, you would need to implement prepareDebit call and provide your server endpoint initializing PayPal via PaymentJs.

Additional Prepare Transaction Parameters (CreateOrder)

Key	Values	Description
extraData.shipping_type	"SHIPPING", "PICKUP_IN_STORE", "PICKUP_FROM_PERSON"	Shipping type
extraData.shipping_cost	string	Shipping cost that will be displayed to the customer
extraData.shipping_preference	"GET_FROM_FILE", "NO_SHIPPING", "SET_PROVIDED_ADDRESS"	By default is being set on the connector level. However, by using this field can be overwritten per transaction. "SET_PROVIDED_ADDRESS" requires to provide shipping details
extraData.brand_name	string	Brand name
extraData.discount_amount	string	Discount amount

One-click payment / Customer Initiated Transaction

To render One-click payment button you would need to do a prepareDebit/preparePreauthorize call to retrieve user-token-id that needs to be passed to paymentJs via paypalOptions.userIdToken.

Example API Request:

{
  "referenceUuid": "referenceUuid",
  "extraData": {
    "useReturnUserExperience": "true"
  },
  "transactionIndicator": "CARDONFILE"
}

Key	Values	Description
referenceUuid	string	Initial transaction UUID
extraData.useReturnUserExperience	string	Expected value: true
transactionIndicator	CARDONFILE	Transaction Indicator should be CARDONFILE

Example API Response:

{
  "data": {
    "success": true,
    "returnType": "FINISHED",
    "widgetToken": "eyJraWQiOiJhMDRiMjEwZDYzYjU0NWQzODEwOWUxNDM3ZjQ3ZWYxMiIsInR5cCI6IkpXVCIsImFsZyI6IkVTMjU2In0.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._s54YCC8MRqjllX2wDTmo4fQyTkUXl6_7aPOiNwBnVBJfLoQlwIZvtrkvgxU7RPBQy3uiRp-hhK4LGvwRC74CA"
