Oney Financement Long


Oney Financement Long is an instalment solution offered by the French acquirer Thunes.

Your customers can split a credit card payment into up to 20 instalments (you define the available amount of instalments in your contract with Thunes). Your customers enter some personal data and their credit card details on the Thunes portal during the initial transaction request. Thunes charges the credit card for the remaining instalments automatically.

The integration is very easy, as you only need to send some additional parameter along with your request.

Your customers need to have a French address and phone number (+33) to use this payment method.
