This chapter will handle all specifics involved with the integration of the payment method TWINT.
A corresponding license and thus a valid identification with a username and password for the Saferpay system.
At least one active Saferpay terminal via which payment can be carried out and the associated Saferpay TerminalId.
A valid TWINT contract
For Twint activation on the Saferpay terminal, please contact your account manager, or our sales team.
The general integration of TWINT can be done via the Payment Page -However other features require a different path. See further down in this chapter- and requires the following things to be noted:
JSON API Version 1.7 or later.
Unlike normal credit card transactions, where a capture could be attempted after the normal reservation time, TWINT does only offer a maximum timeframe of 7 days! After that the transaction will be discarded and a capture will not initiate the money-transfer with the next batch-close, so make sure, to capture your transactions within this time limit!
In justified cases, this period can be extended to 30 days. Please inform our sales department and contact Twint for more information.
Saferpay does support "Pay later" solution offered by Twint. However, one of the available options must be explicitly activated on our side. For more information about different "Pay later" options and their configuration, please contact our sales department.
The parameter OrderId
is limited to 50 characters.
Due to processing limitations, a refund can fail, if it is executed earlier than two hours after the initial transaction. The initial transaction needs to be processed first, until a refund can be executed, which happens within said two hours!
The notification URLs, inside theNotification
container are mandatory, in order to avoid missing payment successes. See the Payment Page process for further information.
Twint User on File saves Twint payment means inside the Saferpay Secure Card Data Store, allowing you to execute subsequent/recurring transactions on a users Twint account.
The following requirements are to be met, if Twint User on File is to be used, aside the normal requirements:
A valid license with access to the Payment API and Secure Card Data.
JSON API Version 1.14 or later
The registration can be done two ways.
Via the Payment Page, during a transaction.
Via the Standalone registration, see below.
The Standalone Registration is done via the Saferpay Alias Store. Within the Alias Insert Request, you need to specify the parameter Type with the value TWINT, which signals, that you want to save Twint payment means.
The RedirectUrl then needs to be opened inside an iFrame, as a redirect, or lightbox. Saferpay will then present the following screen.
Once this process is done, the user gets redirected towards one of the previously defined ReturnUrls, depending on the outcome.
The merchant system then needs to execute the Alias Assert Insert Request, in order to gather the alias and other important payment mean details.
One speciality with Twint User on File is, the Twint.CertificateExpirationDate parameter. Each registered Twint payment mean, will have its own expiration date within the Twint system, which does not correspond with the Saferpay Alias Lifetime! The parameter will return the expiration date of this registration certificate. Once it has passed, the Twint alias becomes invalid.
Furthermore note, that using RANDOM_UNIQUE will always return the already existing alias, even if it is expired on Twint side. While it can serve as a mean to filter out already existing customers and thus help preventing double-registrations, you must keep this in mind. Should you get a rejection saying, that the alias has expired on Twint side, you must first delete the old alias, before your customer can re-register.
Once you have obtained the alias, you can go ahead and execute your recurring/subsequent transaction using the Transaction AuthorizeDirect request. The alias is set within the PaymentMeans.Alias
container, but remember, that this transaction, like all Twint transactions, also must be captured for the money to flow.
If you are integrating Twint inisde a web-view, you may have to specifically configure your view, in order for the Twint app to open.
Here is example-code on how this is achieved.
This code has been directly provided by Twint. If you have any questions, please ask Twint for help.
Please refer to this chapter, if you want to test TWINT.
