Demo or Productive Transactions

You can mark a request and transaction as demo using the parameter demo. If marked so, the payment is not actually processed. There are also no transaction costs, shipments, nor statement positions.

JSON
{
"demo": 1,
    "amount": 6800,
    // ...
}

If the parameter is transmitted with the value 1 or true, it is a demo transaction. If the parameter is omitted, or transmitted with 0 or false, it is a real transaction.
