3DS Setup SDK

The 3DS Setup SDK enables you to collect the user's device information. This information determines whether a transaction is high-risk and whether a challenge is necessary for additional verification. After collecting the information, you can continue with the payment. This page explains how to integrate and use the SDK to collect user information.

Requirements

Before integrating the 3DS into your system, be sure to enable 3DS in your Yuno Dashboard and specify the scenarios in which you want your customers to be able to use it. For additional information, access the Direct Workflow page.

Step 1: Add Yuno SDK

With the three_d_secure_setup_id in hand, you need to include the Yuno SDK file in your webpage before closing the <head> tag. See the example below:

<script src="https://sdk-web.y.uno/v1/static/js/main.min.js"></script>

Step 2: Get the Setup Id

Before starting the payment flow, you have to request a setup Id (three_d_secure_setup_id). For each payment, you need to generate a new three_d_secure_setup_id. Use the 3DS Setup endpoint to get the three_d_secure_setup_id. You need to inform your Yuno account_id and the card information used in the payment.

Availability

This operation is only available for PCI compliance merchants, as you would be handling customers' card data.

Step 3: Start the data collection

To initiate the data collection necessary for the 3DS payment flow, you will use the Yuno.threeDSecure.setup() function. The following table lists all the required parameters for initializing the setup() function.

Required Parameter	Description
`setupId`	Refers to the `three_d_secure_setup_id` obtained in Step 2.
`publicApiKey`	Refers to your Yuno's `public-api-key`, available on the Yuno's Dashboard.
`accountId`	Refers to your Yuno's `account-id`, available on the Yuno's Dashboard.

Misconfiguration Risk

Improper configuration of the acquirerBin, acquireCountryCode, merchantID, and mcc parameters can lead to issues in the transaction liability shift.

The next code block presents an example of initialization.

Yuno.threeDSecure.setup({
      publicApiKey: '<public-api-key>',
      setupId: '<three_d_secure_setup_id>',
      accountId: '<account-id>',
    }).then(({status}) => {
      //SUCCEEDED or ERROR
    })

After executing the setup() service, the Yuno system will receive the necessary device information. Thus, you can continue with the payment. Remember always to use thethree_d_secure_setup_id to identify the device where the payment is being made.
