PCI token creation service

This token creation service allows PCI-DSS merchants to create a token by passing card information in the query.

Under PSD2, cardholder authentication via the 3D Secure protocol is mandatory. The service authenticates the cardholder and returns authentication information at the end of the process.

General principle

This WS allows the creation of an alias of the card sent in the request. Therefore, it will be possible to use this alias during future payments without having to re-enter the buyer's card information.

To do this, the call to the PCI/Charge/CreateToken web service triggers a verification transaction. As mentioned previously, within the framework of PSD2, it is mandatory to authenticate the cardholder via the 3D Secure protocol. The process is therefore as follows:

Call to the PCI/Charge/CreateToken web service
The response can be of 2 types:
- AuthenticationResponseData : This response indicates that it is necessary to proceed with the authentication of the cardholder. You will then need to call back the same PCI/Charge/CreateToken with the result of the instruction for 3D Secure authentication.
- Charge/Payment : This response indicates the end of the verification and the creation of the alias. It is then possible to check the result in the response.

Since authentication plays an important role in this web service, its operation is presented below:

Authentication scenario

The service adopts an operating principle that ignores the underlying protocol to provide a unique integration experience, and not integration by protocol.

The generic process of complete authentication consists of several stages:

An initial call to the PCI/Charge/CreateToken service with a response of AuthenticationResult or AuthenticationInstruction type.
If the return belongs to theAuthenticationInstructiontype, the operation must be performed on the merchant side:
- Creation of a visible or invisible iFrame.
- In the iFrame, browser redirection to a target page after submitting a form that respects the definition specified in the instruction.
- Potential interaction with the cardholder or the browser.
- Return page of the remote server that will emit a JavaScript event containing the result of the instruction.
- Interception of the instruction result in the form of a JavaScript event in the parent window.
- New call to the PCI/Charge/CreateToken service with the signed instruction result received via the browser.
- The PCI/Charge/CreateToken service returns either an instruction or a result once again.
If the return is of AuthenticationResult type, it will contain the final authentication result and the process is complete.

Detailed flowchart

The following flowchart presents a generic payment scenario with authentication: the initial call to the service, an instruction, an interaction, the final authentication result and the end of payment.

CLIENT

Browser

iFrame

Merchant server

Payment gateway server

Remote server (e.g.: ACS)

We will present the different steps of the integration in the following paragraphs.

Integration	Steps
Actions to perform on the merchant server side	Steps 3 , 4 , 16 and 17
Actions to perform on the JavaScript side	Steps 5 , 6 , 7 and 15

Steps 1 and 2: Initiation (payment or adding a card)

A payment or card registration action has been initiated and requires authentication.The PCI/Charge/CreateToken service is now ready to be called.

Step 3: Calling the PCI/Charge/CreateToken service

The initial request allows to transmit the data required for authentication.

Among this information, it is necessary to fill in some information about the client's browser or mobile device in the device object.

This information is mostly technical and must be retrieved from the browser or the mobile device (in JavaScript for example).

The goal is to facilitate customer identification (IP address) and their payment medium (browser size) for a more suitable authentication process.

See the integration documentation of the PCI/Charge/CreateToken service for more information on this field.

Here is an example describing the initial request:

}

It consists of:

The	Function
id	Unique identifier of the authentication transaction in progress.
operationSessionId	Unique session identifier for the current operation. It has to be passed to each new call.
protocol	Indicates which protocol will be eventually applied during the authentication.
value	Represents the result of the authentication or the instruction to follow. If value is of type AuthenticationInstruction , it is an instruction to be executed, if it is of type AuthenticationResult , it is the result of authentication.

If an instruction was returned in the previous step, the page displayed in this step must allow:

To set up a listener for the type of event returned by the iFrame, which will trigger a POST to the merchant server with the instruction result (see step 15 ).
To create a hidden or visible iFrame (see steps 6 and 7 ).

Step 6: Creation of an iFrame

The instruction received in step 4 is as follows:

{
    
    "instructionType": "FORM",
    "name": "CHALLENGE",
    "timeout" : "15",
    "target": {
        "element": "IFRAME",

        "width": 400,
        "height": 400,
        "_type": "V4/PCI/Charge/Authenticate/InstructionTarget"
    },

    "http": {
        "method": "POST",
        "url": "https://acs.sg.com/1.0.2",
        "headers": {
            "Accept": "text/html"
        },
        "body": {

        },
        "_type": "V4/PCI/Charge/Authenticate/HttpRequest"
    },
    "_type": "V4/PCI/Charge/Authenticate/AuthenticationInstruction"
}

The different properties of the iFrame to be created can be found in the target element:

		"target": {
		  "element": "IFRAME",
		  "visible": true,
		  "width": 400,
		  "height": 400
		}

If it must be visible ( value.target.visible attribute set to true ), create the iFrame with these parameters (using width and height ) and display it, or create a hidden iFrame.

Handling the iframe display timeout

It is also necessary to manage the maximum display time of the iframe if the value.timeout attribute is present in the instruction (timeout defined in seconds). To do so, it will be necessary to allow to trigger an event of LYRA_AUTH_INSTRUCTION_RESULT type populated as follows:

{
    eventName: 'LYRA_AUTH_INSTRUCTION_RESULT',
    value: {
        name: "Add here the instruction name you have received in the answer",
        value: 'TIMEOUT',
        protocol: "Add here the protocol object you have received in the answer"
    }
}

Example of implementation:

    function createInstructionIframe(instruction) {
        // Get instruction container element
        container = document.getElementById('instructionContainer');

        // Clean instruction container
        container.innerHTML = ';

        // Create iframe element
        var iframe = document.createElement('iframe');
        iframe.id = 'instructionIframe';
        iframe.name = 'instructionIframe';
        iframe.src = 'about:blank';
        iframe.style.width = instruction.value.target.width+"px";
        iframe.style.height = instruction.value.target.height+"px";
        iframe.style.visibility = instruction.value.target.visible ? 'visible' : 'hidden';

        // Handle timeout
        if(instruction.value.timeout){
            setTimeout(() => {
                const instructionResultTimeout = {
                    eventName: 'LYRA_AUTH_INSTRUCTION_RESULT',
                    value: {
                        name: instruction.value.name,
                        value: 'TIMEOUT',
                        protocol: {
                            name: instruction.protocol.name,
                            version: instruction.protocol.version,
                            network: instruction.protocol.network,
                            challengePreference: instruction.protocol.challengePreference,
                            simulation: instruction.protocol.simulation
                        },
                    },
                };
                window.postMessage(JSON.stringify(instructionResultTimeout), '*');
            }, instruction.value.timeout * 1000);
        }

        // Add iframe to container
        container.appendChild(iframe);

        // Create form to post
        var form = document.createElement('form');
        form.id = 'instructionForm';
        form.name = 'instructionForm';
        form.target = 'instructionIframe';
        form.method = instruction.value.http.method;
        form.action = instruction.value.http.url;
        form.style = 'visibility: hidden';

        // Create form body
        Object.keys(instruction.value.http.body).forEach(function (name) {
            form.innerHTML += '<input name="' + name + '" value="' + instruction.value.http.body[name] + '">';
        });
        var body = document.createElement('form');

        // Add form to container
        container.appendChild(form);

        // Triger form submit
        form.submit();
    }

Step 7: Form submission

Once the iFrame has been created, it must be filled with a form following the instructions of the ‘http’ tag:

"http": {
	"method": "POST",
	"url": "https://acs.sg.com/1.0.2",
	"headers": {
		"Accept": "text/html"
	},
	"body": {
		"termUrl": "https://pass.sample-acs.net/v1/notify/threeds/v1/pares",
		"MD": "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",
		"paReq": "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"
	},
	"_type": "V4/PCI/Charge/Authenticate/HttpRequest"
}

The method property indicates the HTTP verb to be associated with the form.
url indicates which server is targeted by the form action.
The HTTP request headers in headers.
The form parameters in body (e.g. termUrl, MD and paReq).

Once the form has been generated and placed in the iFrame, all you need to do is trigger it when the page is loading.

In case the timeout set in the iframe creation code is triggered, the LYRA_AUTH_INSTRUCTION_RESULT event will be caught by the listener whose details are described in step 15. This will allow the process to continue and have a final result.

Steps 8 to 14: User authentication

Once the form has been posted, the code of the issuing bank will take over the process to allow secure authentication (silent or interactive). At the end of this step, the LYRA_AUTH_INSTRUCTION_RESULT event will be issued from the iFrame to indicate the end of the process. Example:

{
    "eventName": "LYRA_AUTH_INSTRUCTION_RESULT",
    "value" : {
        "value": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c",
        "name": "CHALLENGE",
        "protocol": {
            "name": "THREEDS",
            "version": "2.1.0",
            "network": "VISA",
            "challengePreference" : "NO_PREFERENCE",
            "simulation": "false"
        }
    }
}

Step 15: Retrieval of the JavaScript event emitted in step 14

In order to interpret the LYRA_AUTH_INSTRUCTION_RESULT event, it is necessary to implement a listener on the main page. It must be capable of parsing JSON code and must be written as follows:

window.addEventListener('message', function (messageEvent) {
    
    var data = messageEvent.data;
    try {
        var messageData = JSON.parse(data);
        if (messageData.eventName === 'LYRA_AUTH_INSTRUCTION_RESULT') {
            try {
                // callback call with messageData.value content
                container = document.getElementById('instructionContainer');
                var form = document.createElement('form');
                
                form.method = 'POST';
                form.action = "https://myhost.com/payment/authentication/result.php";
                form.style = 'visibility: hidden';					
                    
                form.innerHTML += "<input name='messageData' value='" + data + "'>";  
                                
                var body = document.createElement('form');
                
                container.appendChild(form);
                form.submit();
            } catch (err) {
                // error callback call
            } finally {
                // always close the iFrame/popin
                container = document.getElementById('instructionContainer');
                container.remove();
            }
        }
    } catch (err) {
        // process eventual exceptions during callbacks
    }
    
}, false);

After that, you must return this data to the merchant server.

Step 16: Returning the instruction result to the merchant server

Once the instruction result is retrieved on the merchant server side, it must be returned via a new call to the PCI/Charge/CreateToken service. The request should contain the instructionResult object as well as the operationSessionId session identifier, received in the response of step 4 :

Step 17: Receiving the response from the payment gateway server

As in step 4 , the merchant server receives a new response, which can either be final ( AuthenticationResult ) or request a new instruction ( AuthenticationInstruction ). In the latter case, the flow resumes at step 5. Here is an example of the final message:

      }
    }

Step 18: The merchant server resumes operations

If the previous response is a final result, the token creation is complete.

Appendix

Example: v2 3DS authentication with ACS authentication

An initial call to the PCI/Charge/CreateToken service with a v2 3DS enrolled card.
A return with a FINGERPRINT instruction (3DS Method).
A redirection to the ACS in the invisible iFrame, loading and execution of the JavaScript code of the ACS fingerprint.
A return via the browser with an instruction result.
A new call to the PCI/Charge/CreateToken service transmitting this result.
A return of the payment gateway server with a CHALLENGE instruction of redirection to the ACS with a CReq (visible iFrame).
The instruction has occurred (redirection to the ACS with a CReq and user interaction).
The return via browser is an instruction result: new call to the PCI/Charge/CreateToken service transmitting this result.
The server return is the final result of the authentication.

Glossary

3DS Method	JavaScript code of the ACS executed in the Buyer’s browser for the purpose of making fingerprints.
3DS Requestor	The requestor upon 3DS authentication, usually the Merchant or their payment gateway.
