Implementation

Step 1: Present a new mandate for signature.

The mandate does not exist yet. You must proceed to the signature of a new mandate by following these steps:

Establish interaction with the payment gateway.
Please see chapter Establishing interaction with the payment gateway.
Configure notification rules.
You must configure at least the notification rule at the end of payment and in case of an abandoned payment.

Please see chapter Setting up notifications.
Generate the payment form.
The procedure is described in the chapter Creating a recurring mandate signature request.

If you want to create a single payment on the day the mandate is signed, see chapter Registering a recurring mandate with a payment.
Redirect the Buyer to the payment page.
Please follow the instructions in the chapter Redirecting the buyer to the payment page.
Analyze the notification.
The specific data transmitted during the notification are indicated in the chapter Analyzing the result of the mandate creation.

If the mandate already exists (see chapter Importing existing mandates), continue to step 2.

Step 2: Issue a direct debit request.

The available solutions are listed in the chapter Issuing a direct debit request.

Step 3: Follow up on direct debit processing.
