Implementing ATW button

For Samsung Wallet integration, you need to insert an "Add To Wallet" script into your system. To implement an "Add to Wallet" button, follow the procedure below:

First, proceed with script composition with the sample script on the Partners Portal or refer to the Integration sample code.
Create the tokenized card data (Cdata). Card data is the actual content of the wallet card and it has several formats based on the card type. Refer to the CData Generation Sample Code for details.

ImportantThe card data token expires in 30 seconds after creation, so it needs to be created right after the user clicks the “Add to Wallet” button.

For "Add to Wallet" integration, you may also need some base data. You can find that and other necessary information on Partners Portal.

Samsung Wallet on the Web

This section explains how to implement an "Add to Wallet" button using JavaScript in a web view.

Web Button Reference with Importing API JavaScript

If you implement the "Add to Wallet" button using this script, the button is shown only on the devices that support Samsung Wallet.

To automatically parse <samsung:wallet> HTML tags when the page is loaded, include the following standard JavaScript:

<script src="https://us-cdn-gpp.mcsvc.samsung.com/lib/wallet-card.js" type="text/javascript"></script>

You can use these tags or JavaScript functions for the web button if you're rendering HTML and you have proper partner permissions. You can also use the script by referring to the various attributes.

samsung:wallet HTML Tag

The ‘samsung:wallet’ namespace tag defines the placement and various attributes of the "Add to Wallet" web button for Samsung Wallet.

<samsung:wallet
cardid="CARD_ID" cdata="CDATA" partnercode="PARTNER_CODE" buttonid="BUTTON_ID" 
rdclickurl="RD_CLICK_URL" rdimpressionurl="RD_IMPRESSION_URL"
></samsung:wallet>

Button attributes

onclickbutton	Function	N	Callback handler function for the button’s on-click event. If you register the handler function, you must return a callback or promise value. * Refer to Usage of onClickButton Handler for more details.

samsungWallet.addButton Function

This function allows you to explicitly render the Samsung Wallet API for the "Add to Wallet" web button.

samsungWallet.addButton({
	cardId: "CARD_ID",
	cdata: "CDATA",
	partnerCode: "PARTNER_CODE",
	targetId: "TARGET_ID",
	buttonId: "BUTTON_ID",
	RDClickUrl: "RD_CLICK_URL",
	RDImpressionUrl: "RD_IMPRESSION_URL",
})

Button attributes

Unlike the samsung:wallet HTML tag, you must use camelCase in the button attributes in function case.

Attributes	Type	Required	Description
cardId	String	Y	Wallet card identifier. * Value granted from the Partners Portal.
cdata	String	Y	Encrypted card object (JSON). * This field needs to be encrypted. * Refer to Security for more details.
partnerCode	String	Y	Partner code. * Value granted from the Partners Portal.

Default: default. default: Load the button’s theme according to the prefers-color-scheme policy. inversion: Load the inverse of the default button’s theme. lightonly: Load the light theme of the default button. darkonly: Load the dark theme of the default button.
style	Object (CSSStyleDeclaration)	N	Load the button with a custom style
onShowButton	Function	N	Callback handler function for the button’s on-show event.
onClickButton	Function	N	Callback handler function for the button’s on-click event. If you register the handler function, you must return a callback or promise value. * Refer to Usage of onClickButton Handler for more details.

Usage of onClickButton Handler

You can choose whether to proceed with the next "Add to Wallet" step using a promise or a callback function, if you register a callback handler in onClickButton. We recommend that you add the process of generating JWT cdata (add cdata to options.cdata) to this handler, because of the cdata expiration time. The function parameters are defined as follows.

Attributes	Type	Required	Description
options	Button attributes	N	Attributes of the current button
callback	Function	N	Callback function to pass the flag to proceed. Default: false.
(Promise resolve)	Function	N	Promise-resolved value to pass the flag to proceed Default: false.

Callback to web button process from callback attributes (for ES5)

By executing a callback function with a flag, you can proceed to the next 'Add to Wallet' process.

onClickButton: function (options, callback) {
    // TODO partner's process
    callback(flag)
}

Callback to web button process from returning Promise (for ES6)

By returning a promise with a resolving flag, you can proceed to the next ‘Add To Wallet’ process.

onClickButton: async (options) => {
    return new Promise(async (resolve, reject) => {
        // TODO partner's process (await)
        resolve(flag)
    })
}

ImportantThe card data token expires in 30 seconds after creation, so it needs to be created right after the user clicks the “Add to Wallet” button.

Samsung Wallet on a Native Application

The following outline explains how to implement the "Add to Wallet" button on a native application.

Get button graphic resources from a repository depending on your service environment. For more information, refer to Image resources.
Check availability by calling the "Check service available devices" APO, then determine whether to show up the "Add to Wallet" button on the user device.
A. If "available" on response has "true" -> SUPPORT
B. If has "false" -> NOT SUPPORT
Implement a JWT web link on the button triggered action.

Samsung Wallet on an MMS/Email

The following guides how to configure wallet code on email and MMS messages.

Implement the Data Fetch Link process, including server APIs. You need to create a unique "reference ID". For security reasons, make sure the "reference ID" is complex enough that no important information can be inferred.
Deliver a message including the web link through the chosen message platform. For MMS, the designed link shows up as a "Smart Suggestion" on Samsung devices. You can find a sample web link on the Wallet Cards guide on the Partners Portal.
For card data, Samsung Wallet asks the partner system to provide card details through the server API.
Duplicate requests are prohibited on the same device.

Link to “Add to Wallet” on an MMS/Email

You can add an “Add to Wallet” web button even in environments where the JavaScript API cannot be loaded, such as SMS or email.

These methods do not support controlling “Add to Wallet” button visibility.
