From the perspective of your loyalty integration there are three ways to pay:

  • only by secucard;
  • only by credit card, or SEPA direct debit;
  • partially by secucard, and the missing sum by credit card, or SEPA direct debit.

Your system tells our API when the payer wants to use his secucard. In our answer, you see, whether it can be paid with this card, or how much is the missing, that needs to be paid by one of the other methods.

Apply the Loyalty Card for Payment

In order to use the card balance for payment, you need to call POST /api/v2/Smart/Transactions/{id}/preTransaction. If you only want to charge the card, or track revenue to gain balance, you need not call this endpoint.

We apply the card balance to our Smart Transaction:

Request
POST /api/v2/Smart/Transactions/STX_3QPGBB72F2NSPDS95JZPWA772DUMAZ/preTransaction HTTP/1.1
Host: connect-testing.secuconnect.com
Authenticate: Bearer qb56tjj1bcvo9n2nj4u38k84lo
Accept: application/json

If everything is fine, the API responds with 200 OK and some details:

Response
HTTP/1.1 200 OK
Content-Type: application/json
...
 
{
"missing_sum": 725,

"ean": "1111111119",
"quantity": 1,
"priceOne": -18,
"tax": 19,
"desc": "Bonus Steuer 19"
}]
}

The buyer would spend €0.71 with bonus balance. There are €0.53 collected for articles with the reduced VAT rate of 7%, and €0.18 for the full rate of 19%.

In this example the buyer would have to pay €7.25 using another payment method. If there was also cash balance after spending the full bonus balance, the missing_sum would be be decreased even more.

Monetary amounts are expressed in the smallest currency unit (e. g. Euro Cent).

These details also appear in the Smart Transaction now:

Request
GET /api/v2/Smart/Transactions/STX_3QPGBB72F2NSPDS95JZPWA772DUMAZ HTTP/1.1
Host: connect-testing.secuconnect.com

As you see, the Smart Transaction is in status processing now (line 10). There is no Loyalty or Payment Transaction (line 8), and the card is not charged yet (lines 137–139).

The missing sum is visible in the basket_info (line 96), and the special bonus items are added to the basket now (lines 58–88).

The system needs to remember the missing sum. If there is no remainder (missing_sum is 0) you have to execute a pure card payment. Otherwise you need to run the process for credit card or SEPA direct debit payment.

Pay Fully by Secucard

Given you have called preTransaction and received a missing_sum of 0 (zero), and the order can be paid fully by secucard. You need to call the endpoint to execute a pure loyalty transaction:

Request
POST /api/v2/Smart/Transactions/STX_3QPGBB72F2NSPDS95JZPWA772DUMAZ/start/loyalty HTTP/1.1
Host: connect-testing.secuconnect.com
Authenticate: Bearer qb56tjj1bcvo9n2nj4u38k84lo
Accept: application/json

There is no need for a previous authorization call (endpoint POST /api/v2/Smart/Transactions/{id}/prepare) here.

If everything is fine, the API responds with HTTP status 200 OK, and the new object representation:

Pay the Remainder by Credit Card or SEPA Direct Debit

Given you have not applied the card with preTransaction, or there was a missing_sum that needs to be paid by credit card or SEPA direct debit. In the Getting Started section we have demonstrated this for SEPA direct debit.

The payment process is exactly the same like for other e-commerce payments. There are two different guides explaining this. If you haven't implemented it yet, you need to consult one of these guides:

The only difference is that you find a receipt node in the Smart Transaction after you have started it.

This is our call to execute the already authorized payment:

Monetary amounts are expressed in the smallest currency unit (e. g. Euro Cent). This applies to all basket details, and the card details. In contrast, the receipt lines are text lines, and the amounts are already formatted.

Status ok, received or collection means you can deliver. Status pending means you have to wait for one of these statusses. Status failed means the payment failed, and you must repeat the payment process.

Print the Receipt

Example Smart Transaction with Receipt

After the payment was executed, the Smart Transaction may contain a receipt:

PDF for similar receipt

There are four types of receipt lines. You can distinguish them by the type field:

  • separators with optional headline;
  • plain textlines;
  • name-value lines;
  • space lines.

Furthermore there are some decorations to emphasise lines, or to align the text at the line.

Separator Line

The separator line starts a new receipt with a caption:

Receipt Line
{
"type": "separator",
"value": {
"caption": "Kundenkarte Aufladung"
}
}

The separator line is like a headline. It needs to be centered, and is printed bolder and larger than normal text. It should be padded with some space at the top and the bottom.

The attribute caption is optional:

Receipt Line
{
"type": "separator",
"value": {
}
}

If there is no caption, you can print a horizontal line instead, or just a number of dashes.

Separator lines have no decorations.

Text Line

A text line, here with decoration important:

Receipt Line
{
"type": "textline",
"value": {
"text": "10,00 EUR",
"decoration": [
"important"
]
}
}

Text lines can have one or more of these decorations:

  • important (print it bold);
  • align-left
  • align-center
  • align-right

The default alignment is to the left.

Name-Value Line

A name-value line, with one text adjusted to the left, the other to the right:

Receipt Line
{
"type": "name-value",
"value": {
"name": "Kartennummer:",
"value": "9276004429942845",
"decoration": []
}
}

Name and value shall be printed at the same line. The name is adjusted to the left, and the value to the right.

Name-value lines can have the decoration important. Here goes the same like for normal text lines. It needs to be printed bolder.

Space Line

This is a space line:

Receipt Line
{
"type": "space"
}

A space line is used to add some vertical space between a series of normal text or name-value lines. It is used to form text sections.

Space lines have neither attributes nor decorations.
