Description

With the TWINT app, you can make payments easily and conveniently: in online shops, at supermarket cash registers, in canteens, and at vending machines. With TWINT, you can transfer money in real-time – easily from smartphone to smartphone. And you can also request and receive money from friends and family.

Datatrans gives you with the option to integrate TWINT in your web shop and in your native mobile applications. Additionally, Datatrans supports the tokenization of TWINT - User on File.

WebView To App Switch

In case you are using a WebView in your mobile applications to process payments with TWINT and not our mobile SDKs, you will need to modify your request to allow a smooth switch from your app to TWINT. Please contact us if you wish to allow an App Switch from your WebView to Twint.

Test Environment

To test TWINT, you will need to download a test app and go through the registration process again. Using the productive TWINT app will not allow you to test TWINT payments. You can open the following links to download the so-called 'TWINT Configurator' and finally the test application:
Configurator Android: dtrx.ch/twint-android 🔗
Configurator iOS: dtrx.ch/twint-ios 🔗

Please select the PAT environment for your tests via Datatrans. To top up your test account you will require voucher codes that are available on request.

Registering a TWINT wallet

To register a TWINT wallet so that you are able to debit an account without user interaction, you will need to create a dedicated registration. This can be done by sending the amount parameter set to 0 (amount=0) and useAlias to 'yes' (useAlias=yes). After a registration was successfully created, we will return the TWINT token in our response parameter aliasCC.

For registrations to work, you need to make sure that your TWINT account has the option 'User on File (UoF)' activated. This can be activated upon request from your TWINT account manager. Please make sure to upload a merchant logo to your TWINT store configuration, or you might run into bugs within the app. You can refer to the section Create an Alias of our docs for further information in how to create an alias.

Server to Server API calls

After a transactionId or aliasCC value was received by completing a payment or registration, the following server to server API calls can be used to do further actions.

Authorization

🚧

Requirement: User on File (UoF)

Please make sure to have the option 'User on File' activated in your account to be able to use the Authorization API with TWINT. Make sure to also add a logo to your store configuration to avoid issues in production.
