Payments are made in three easy steps:
You arrange a Smart Transaction with the details.
Then you direct your customer to the returned URL or make it open in a layer. The customer makes the payment with us.
Finally you receive him back at your success URL. The status of the transaction tells whether you need to wait for the payment or can already deliver.
There are also mail notifications and secuOffice to manage payments. The shipping date for invoice payment can be set via API or in secuOffice.
