SEPA Direct Debit (SDD) integration

Introduction

SEPA direct debits (SDD) is a payment method fully deployed in euro area countries.

It is a “pull” payment method that allows a merchant to directly debit a user’s bank account, as long as a valid mandate has been signed by the user to allow the merchant to withdraw money from his bank account.

It involves redirecting the user to a specific interface to enter his IBAN and finalize its transaction.

info

Upon receipt of EXECCODE = 0002 in the synchronous response, you must redirect the cardholder to a specific interface by displaying the content of the REDIRECTHTML parameter. (Base64 encoded)

info

When processing the first successful transaction, an e-mandate is automatically generated by the platform and an ALIAS is also returned. This ALIAS should then be used to collect the linked mandate again.

warning

Final status of the transaction may not be known before a few working days.

Compatible operations and options

Server to server integration

In this mode, you have to send a POST request containing your order’s parameters over HTTPS to the Dalenys platform.
