SDD Transaction

An SDDTransaction is a direct account-to-account between a merchant (creditor) and a customer (debtor).

The first pre-requisite for a SDDTransaction to occurs is two bank account with the right types must exist. Only your (a merchant) account can be a creditor account. The debtor account can be created by the following process. The second pre-requisite is a Mandate must be signed by the two parts.

The steps to create a SDDTransaction

1Create a bank Account Identity (debtor)

  • Retrieve the customer informations (and evenually create a customer)
  • Once an identity created, an identityId will be generated

2Create the bank Account (with the identityId and the customer object)

  • Retrive new informations from the customer
  • Transmits it to us, with the identityId and the customerId of your customer
  • A bankAccountId will be generated at the creation

3Create a mandate (with the two bankAccountId and the customer object)

  • Multiple Mandates can be created with the two same bank accounts.
  • Determine a type of mandate (Ponctual or Recurrent).
  • Transmits to us the informations of the mandate, with the bankAccountId of the creditor, the bankAccountId of the debtor and the customerId
  • A mandateId and an OTP will be generate at the creation. The OTP will be sent at your customer via SMS.

The OTP is a secret code system the customer will receive, and it will allow you and your customer to validate or sign contract safely.

The OTP has a lifespan of 15 minutes, so it is possible to renew it with or without a new phone number.

4Sign the mandate (with the OTP)

  • Retrieve the secret code of your customer
  • Transmits it to us, with the mandateId
  • By this action, the mandate is regarded as sign by the two parts

5.1Create a SDDTransaction (with the mandate)

  • You can now create a SDDTransaction.
  • Configure your SDDTransaction, by enquire your wanted informations, and join the mandateId
  • For more safety, you can force an OTP for he validation of each SDDTransaction : in this case, an OTP will be generated at the creation and sent at your customer via SMS. A sddTransactionId will also be generated at the creation.
  • By default, the validation of the SDDTransaction is automatic.

5.2Validate the SDDTransaction (if an OTP validation has been configured)

  • This step is necessary if you configured an OTP validation for the SDDTransaction
  • Retrieve the secret code of your customer
  • Transmits it to us, with the sddTransactionId .
  • By this action, the SDDTransaction is regarded as validated and will be executed.
