Multiple payment methods
Technical manual for integrating a payment component using multiple payment methods.
This technical manual is for integrating a payment component using multiple payment methods.

1. Add the HTML elements
-
Add the component's CSS to the
<head>
of your checkout page:<link rel="stylesheet" href="https://testpay.multisafepay.com/sdk/components/v2/components.css">
-
Add the component's script to the bottom of the
<body>
of your checkout page:<script src="https://testpay.multisafepay.com/sdk/components/v2/components.js"></script>
-
Add the DOM element for the component's UI in the
<body>
of your checkout page:<div id="MultiSafepayPayment"></div>
Choose your payment button
Decide if you want to:
-
Generate a button with the component (see Step 2 below). Recommended.
-
Use an existing button, e.g. if your checkout already includes one.
-
Create your own button:
<button id="payment-button"></button>
2. Initialize the component
Generate an API token
Payment components require a MultiSafepay API token. See API reference ā Generate an API token.
ā Ā Tip! To keep your API key private, request the token from your own server.
Construct the component object
-
Initialize an
orderData
object containing information about the customer's order collected during the checkout process:const orderData = { currency: 'EUR', amount: 10000, customer: { locale: 'en', country: 'NL' }, payment_options: { settings: { connect: { group_cards: true } } }, };
Properties
Key Required amount Yes currency Yes customer.country No customer.locale No customer.reference Yes, for recurring payments payment_options.settings.connect.group_cards No recurring.model Yes, for recurring payments template.settings.embed_mode No
How to process recurring payments
Recurring payments is a solution that lets you store a customerās payment details as a secure, encrypted token.
Upon subsequent payments, customers can select their stored payment details and pay with a single click.
To process recurring payments in your payment component:
- Add the
cardOnFile
recurring model - Make List tokens request from your server and provide a
tokens
const orderData = { currency: 'EUR', amount: 10000, customer: { locale: 'en', country: 'NL' }, template : { settings: { embed_mode: true } } }; const recurringData = { "model": "cardOnFile", "tokens": [ { "token": "AvqeOjgdm8A", "code": "IDEAL", "display": "xxxxxxxxxNL81PSTB0000012345", "bin": null, "name_holder": "Schilder", "expiry_date": "", "expired": 0, "last4": null, "model": "cardOnFile" }, { "token": "BcEWsknWsYg", "code": "MASTERCARD", "display": "Card xxxx xxxx xxxx 4444", "bin": 555555, "name_holder": "Holder", "expiry_date": 2412, "expired": 0, "last4": 4444, "model": "cardOnFile" }]};
Success
Your payment component now automatically renders a checkbox where customers can choose whether they would like to store their payment details for future visits.
Recurring payments are supported for all card payments.
š Note: To test card details, see Test payment details ā Credit and debit cards.
To use recurring payments in your payment component, you need to enable recurring payments for your account. If you haven't already, email [email protected]
š Note: We use the
orderData
object to ensure the payment methods are enabled, e.g. for the currency, country, and order value. - Add the
-
Construct a
PaymentComponent
object in thetest
environment using theorder
object and your API token:PaymentComponent = new MultiSafepay({ env: 'test', apiToken: apiToken, order: orderData });
Initialize the component
Initialize the component using:
In the method call, create event handlers for the following events:
Events
Event | Event handler |
---|---|
onError | Occurs when there is an error in the payment component. |
onLoad | Occurs when the payment component UI is rendered. |
onSelect | Occurs when the customer selects an issuer with iDEAL. |
onSubmit | Occurs when the customer clicks the payment button (when using the button generated by the component). |
onValidation | Occurs when form validation changes. Can be used to disable the payment button until all fields are validated. |
The PaymentComponent
has the following methods:
Methods
Method | Description |
---|---|
getErrors | Returns error messages or codes. |
hasErrors | Returns a boolean value about whether errors were registered. |
getOrderData | Returns an object containing a payment_data object and the full order configuration. |
getPaymentData | Returns a payment_data object with a payload containing the customer's payment details, used to create orders, and the gateway . |
3. Create an order
Handle the interaction
ā Ā Tip! This step only applies if using your own or an existing payment button.
-
Assign the button element to a variable:
const paymentButton = document.querySelector('#payment-button');
The payment_data
includes the following parameters:
{
"payment_data": {
"gateway": "CREDITCARD",
"payload": "xxxxxxxx",
"tokenize": true
}};
Parameters
Key | Required | Description |
---|---|---|
gateway | Yes | The unique gateway_id to redirect the customer to the specific payment method. |
payload | Yes | Information required to process the payment. Note: Do not edit or modify the payload or otherwise the payment fails. |
tokenize | Optional | For recurring payments. If a customer selects to either save their cardholder data for future visits or use an existing token, a payment_data.tokenize parameter is added. |
Note: When payment_data.tokenize
is set to true
you need to append customer.reference
to the order data.
-
Create an event handler for the payment button:
- When the customer clicks the payment button, call the component's
getPaymentData()
method. - Send the response to your server and create an order.
- Return the reponse from your server to the client-side to redirect the customer.
- When the customer clicks the payment button, call the component's
Redirect the customer
The component's redirection
handler redirects the customer to the relevant page:
- If customer actions are required to complete the payment (e.g. by completing 3D Secure or iDEAL issuer authentication), the customer is redirected to the relevant page. If successful, the customer is then redirected to the
redirect_url
, i.e. the "success page". - If no customer action is required to complete the payment, the customer is redirected to the
redirect_url
, i.e. the "success page". - If the customer chooses to pay by bank transfer, the component displays the banking details needed for customers to complete payment.
- If a QR code is available for customers to complete payment on their mobile device, the component displays the QR code.
Avoid duplicate orders
When using your own payment button, if the customer clicks it again before they are redirected, this can create duplicate orders.
To avoid duplicate orders, disable the button until you have attempted to create an order.
Then, check response.success
:
-
If
true
, don't re-enable the button, and proceed with the redirect. -
If
false
, re-enable the button for the customer to try again.paymentButton.addEventListener('click', e => { paymentButton.addAttribute('disabled'); if (PaymentComponent.hasErrors()) { let errors = PaymentComponent.getErrors(); console.log(errors); return false; } createOrder(PaymentComponent.getPaymentData()).then(response => { if(!response || !response.success) { paymentButton.disabled = false; console.log(response); } else { PaymentComponent.init('redirection', { order: response.data }); } }); });
Create an order
Create an order from your server, appending the payment_data
collected from the payment component UI to the order data.
See API reference ā Create order > Payment component.
4. Go live
To test the payment methods, see Testing payment methods - [(/docs/testing#test-payment-details).
When you're ready to process real payments, make the following changes:
-
In Step 1: Add the elements, replace the test JavaScript library with the live JavaScript library:
<script src="https://pay.multisafepay.com/sdk/components/v2/components.js"></script>
Next, replace the test CSS file with the live CSS file:
<link rel="stylesheet" href="https://pay.multisafepay.com/sdk/components/v2/components.css">
-
In Step 2: Construct the component object, change the environment from
test
tolive
:PaymentComponent = new MultiSafepay({ env: 'live', apiToken: apiToken, order: orderData });
-
In Step 3: Create an order, change the test endpoint to the live endpoint:
