Understanding Bancontact Mobile payments with Worldline Sips

General principles

Bancontact is the market leader in electronic payments in Belgium. The Bancontact card is the Belgian national card.

The Bancontact Mobile means of payment allow customers to pay with their Bancontact card via their mobile phone or tablet.

To pay with a Bancontact card via the Bancontact Mobile application, cardholders must have the Bancontact application installed on their mobile device (computer, smartphone, tablet), and than, they can initialise the transaction. During the payment stage, the Bancontact Mobile application will be launched via two methods, depending on the device:

  • If the transaction is initialised on a different computer or mobile device than the one used for the payment, the Bancontact Mobile application will be launched by the customer on the device used for the payment. By scanning the QR code displayed on the payment page, the customer is redirected to the authentication page.
  • If the transaction is initialised on a mobile device that also serves as a payment device via the dedicated mobile application, that application is launched by clicking on the button URL-intent on the payment page.

As with the standard Bancontact card payments, an authentication step is required. You benefit from a guarantee of payment under certain conditions, according to the current banking regulations. During a Bancontact Mobile payment, the cardholder proceeds to the authentication through the same name application.

If the amount is greater than €1500.00, the transaction will be rejected (Worldline Sips response code 05).

  • Sips In-App which is an interface dedicated to mobile payments.

For Bancontact Mobile payments, it is not allowed to defer the remittance, you cannot adjust the date of funds transfers.

The diagram below explains the different transaction statuses according to the chosen capture mode:

The following table summarises the different response cases to be processed:

Status Response fields Action to take
Payment accepted acquirerResponseCode = 00
authorisationId = (cf. the Data Dictionary).
holderAuthentMethod = PASSWORD
holderAuthentStatus = SUCCESS
holderAuthentProgram = BCMCMOBILE
panEntryMode = WALLET
paymentMeanBrand = BCMC
paymentMeanType = CARD
responseCode = 00
walletType = BCMCMOBILE
 You can deliver the order.
Acquirer refusal acquirerResponseCode = (cf. the Data Dictionary).
responseCode = 05
 The authorisation is refused for a reason unrelated to fraud.
If you have not opted for the "new payment attempt" option (please read the Functionality set-up Guide for more details), you can suggest that your customer pay with another means of payment by generating a new request.
Refusal due to the number of attempts reached responseCode = 75 The customer has made several attempts that have all failed.
Refusal due to a technical issue acquirerResponseCode = 90-98
responseCode = 90, 99
Temporary technical issue when processing the transaction. Suggest that your customer redo a payment later.

For the complete response codes (responseCode) and acquirer response codes (acquirerResponseCode), please refer to the Data dictionary.

Making a Bancontact Mobile payment with Sips Office

The payment process for Sips Office is described below:


steps of a bancontact mobile payment with office

1) The client pays on the payment page you host on your web site. 2) You initialize the payment sending a paymentProviderInitialize request to Worldline Sips who sends you a response. 3) You launch Bancontact mobile app thanks to the redirectionUrl provided by Worldline Sips in the paymentProviderInitialize response. 4) Worldline Sips informs you wether the authentication has succeeded or not. 5) You send a paymentProviderFinalize request to Worldline Sips who sends you the payment result. 6) You display the payment result to your customer.
Initialising a payment (PaymentProviderInitialize)

The Bancontact Mobile payment initialisation is done by calling the paymentProviderInitialize method.

Payment initialisation request

You must populate the following specific fields in the initialisation request for a Bancontact mobile payment:

Field name Remarks/rules
merchantReturnUrl The URL for sending the authentication notification.
paymentMeanBrand Must be populated with BCMCMOBILE.
responseKeyVersion The secret key version used to encrypt the authentication notification.
paymentMeanData.bcmcMobile.defaultRedirectUrl The optional URL for the Bancontact mobile application that can be used as a merchant callback URL for notifications. This callback can be triggered by the mobile application when the payment has not been successful, or if the connection between the mobile application and the payment service has been lost during the processing of the transaction.
paymentMeanData.bcmcMobile.completionRedirectUrl The optional URL for the Bancontact mobile application that can be used as a merchant callback URL for notifications. This callback can be triggered by the mobile application after displaying the payment result to the client.
Payment initialisation response

The following table summarises the different response cases to be processed:

Status Response fields Action to take
Payment initialisation accepted acquirerResponseCode = 00
authorisationId = (cf. the Data Dictionary).
messageVersion = message version retrieved in response to the payment initialisation.
outerRedirectionUrl = QRCode
paymentMeanBrand = BCMCMOBILE
responseCode = 00
redirectionData = redirection data retrieved in response to the payment initialisation.
redirectionUrl = URL-intent
 Redirect the customer to redirectionUrl.
Payment initialisation rejected
responseCode = <> 00
 See the field errorFieldName, then fix the request.
If the problem persists, contact the technical support.
Acquirer refusal acquirerResponseCode = (cf. the Data Dictionary).
responseCode = 05
 The authorisation is refused for a reason unrelated to fraud, you can suggest that your customer pay with another means of payment by generating a new request.
Refusal due to a technical issue acquirerResponseCode = 90-98
responseCode = 90, 99
 Temporary technical issue when processing the transaction. Suggest that your customer redo a payment later.

For the complete response codes (responseCode) and acquirer response codes (acquirerResponseCode), please refer to the Data dictionary.

Customer redirection

At this point, you can choose the process to activate:

  • with the redirectionUrl field, you are able to provide the URL-intent received via the PaymentProviderInitialize response on your mobile application.
  • with the outerRedirectionUrl field, you can also generate a QR code to display on your pages.

Both processes will generate the launch of the mobile Bancontact application installed on the customer's mobile device. The customer will then have to identify himself.

Attention: when the initialize process is done, the customer has a limited time to authorize the payment. The QR code and/or the URL intent must be displayed just after calling the PaymentProviderInitialize method.
Finalising a payment (PaymentProviderFinalize)

This last step allows you to obtain the payment status. The settings obtained during the redirection after the payment process on the Bancontact Mobile website are to be transmitted during this call. The method used to finalise a payment is paymentProviderFinalize.

Tip: you can obtain a code 24 "Operation impossible" in response to your paymentProviderFinalize request. This code means that this request has already been sent and processed for the transaction in question. If you are unable to identify this processing, please use the GetTransactionData function of the diagnostic service: this operation allows you to retrieve information relating to a transaction previously created using the Worldline Sips.
Payment finalisation request

You must populate the following specific fields in the finalisation request for a Bancontact mobile payment:

Field name Remarks/rules
redirectionData Redirection data
messageVersion Message version
Payment finalisation response

The following table summarises the different response cases to be processed:

Status Response fields Action to take
Payment accepted acquirerResponseCode = 00
authorisationId = (cf. the Data Dictionary).
panEntryMode = WALLET
paymentMeanBrand = BCMCMOBILE
responseCode = 00
walletType = BCMCMOBILE
 You can deliver the order.
Acquirer refusal acquirerResponseCode = (cf. the Data Dictionary).
responseCode = 05
 The authorisation is refused for a reason unrelated to fraud, you can suggest that your customer pay with another means of payment by generating a new request.
Refusal due to a technical issue acquirerResponseCode = 90-98
responseCode = 90, 99
 Temporary technical issue when processing the transaction. Suggest that your customer redo a payment later.

For the complete response codes (responseCode) and acquirer response codes (acquirerResponseCode), please refer to the Data dictionary.

Cardholder authentication notification

A notification in HTTP POST is sent to the URL provided in the merchantReturnUrl field related to the initialisation method.

You have to configure a system receiving the notification message to make a call following the PaymentProviderFinalize method (for example, a control service waiting for notification).

Four fields are set in the request (case sensitive):

Field name Remarks/rules
Data The field concatenation is necessary to finalise the transaction.
Setting example: keyVersion=1|merchantId = 099974849505999|…
Encode Coding type in use
Seal Message signature
InterfaceVersion Context message version

If the encoding value is "base64", the data must have a Base64.decode encoding to retrieve the concatenated string.

The concatenated string is structured as follows: key1 = value1 | key2 = value2...

Example:

merchantId=002474849505153|transactionReference=TEST87190508400|redirectionData=+n
lCo8T13xEspDheo56uxiYJql7rAoAVM...1aNpi9l85BveUkuoco=|messageVersion=0.1|keyVersion=1

The following fields are populated in the "Data" field.

These fields must be used to process the payment finalisation.

Field name Remarks/rules
keyVersion The secret key version used to encrypt the authentication notification.
merchantId Merchant Identifier
messageVersion Message version
redirectionData Redirection data
transactionReference Transaction reference
