Web SDK

Web SDK
Judopay's Web SDK is a JavaScript library which includes a fully customisable hosted iframe solution enabling you to collect sensitive card information.
You will not take on additional PCI scope, as sensitive card information such as:
card number (PAN)
expiry date
card security code 
will be submitted by your customers into fields hosted by Judopay.

Creating a 3D Secure 2 Payment with the Web SDK
When authorising /payments or /preauths it is recommended to use paymentSession.
Web SDK Version 0.0.29 (and higher) fully supports 3D Secure 2 flows. No additional support is required, the SDK does the rest.
﻿
﻿
The following steps are prerequisites for all the payment methods﻿ available for integration using Judopay's Web SDK.
Step One: Create a paymentSession
﻿
﻿
Make a HTTP POST Request: /paymentsession
Payment Session Request Example
Response Reference Example
{
  "judoId": "100100100",
  "yourConsumerReference": "2b45fd3f-cee5-4e7e-874f-28051db65408",
  "yourPaymentReference": "6482c678-cad3-4efd-b081-aeae7a89a134",
  "currency": "GBP",
  "amount": 10.99,
  "expiryDate": "2024-02-05T16:28:32.8596+00:00" //if not set, session will expire in 30 minutes
}
{
  "judoId": "100100100",
  "yourConsumerReference": "2b45fd3f-cee5-4e7e-874f-28051db65408",
  "yourPaymentReference": "6482c678-cad3-4efd-b081-aeae7a89a134",
  "currency": "GBP",
  "amount": 10.99,
  "expiryDate": "2024-02-05T16:28:32.8596+00:00" //if not set, session will expire in 30 minutes
}
﻿
﻿
Your backend server should store the paymentSession response reference returned by Judopay's API.
Use this reference from the response to populate paymentSession when calling /payments and /preauths from your front-end client.
See Making a Transaction﻿.
The following parameters need to remain consistent between the /paymentsession requests and the /payments and /preauths requests, otherwise the transaction will fail:
YourPaymentReference
YourConsumerReference
JudoID
Currency
Amount
This is used to cross reference the validity of the transaction.
﻿
Step Two: Add the Payment Form to your Website
﻿
Create and customise the Judopay Web SDK iFrame
﻿
An example of an iFrameConfiguration object:
iFrame Configuration Object Example
//Script to create a minimum iframe:
<script>
const iFrameConfiguration = {
    isGeoLocationGatheringAllowed: true, 
    iframe: {
    language: "en", 
    errorFieldId: 'judopay-errors', 
    showCardTypeIcons: true, 
    layout: "vertical", 
    cardTypeIconRight: "10px", 
    cardTypeIconTop: "-2px",
    backgroundColor: "#FFFFFF", 
    enabledPaymentMethods: ['CARD'], 
    defaultCountryCode: 'UK',
    isCountryAndPostcodeVisible: false, 
    isCardHolderNameVisible: true, 
    errorsDisplay: "HIDE_UNDER_FIELDS", 
    disableUnderline: false, 
    shouldAutofocus: true, 
            }
    }
</script>
//Script to create a minimum iframe:
<script>
const iFrameConfiguration = {
    isGeoLocationGatheringAllowed: true, 
    iframe: {
    language: "en", 
    errorFieldId: 'judopay-errors', 
    showCardTypeIcons: true, 
    layout: "vertical", 
    cardTypeIconRight: "10px", 
    cardTypeIconTop: "-2px",
    backgroundColor: "#FFFFFF", 
    enabledPaymentMethods: ['CARD'], 
    defaultCountryCode: 'UK',
    isCountryAndPostcodeVisible: false, 
    isCardHolderNameVisible: true, 
    errorsDisplay: "HIDE_UNDER_FIELDS", 
    disableUnderline: false, 
    shouldAutofocus: true, 
            }
    }
</script>
﻿
The iframe is created in your <SCRIPT> location.
See below for more details on the parameters that create the iFrameConfiguration object:

Setting up an Incremental Authorisation
The incremental authorisation feature allows you to increment the value of your original preAuth for scenarios where you need to charge your customer a higher total amount.
By incrementing the preAuth value, you will be able to capture the total amount that you wish to charge your customer when you are ready.
The allow increment flag allows you to set up your initial preAuth so that it can be incremented by an additional amount.
This feature is only available with a limited set of processors - please check with your account manager before you use this feature.
allowIncrement is a part of the main JudoPaymentConfiguration config object, and can be set when creating the configuration object.
If present = it is automatically applied for preAuth requests.
If no value is provided = then false is set by default.
Example:
val configuration: JudoPaymentConfiguration = {
 ...
 allowIncrement: true,
};

const judopay = new JudoPay()
judopay.createCardDetails('jupay-payment-iframe', configuration)
