This guide is for a simple webshop with a custom checkout. There are other guides for internet marketplaces, or e-commerce platforms. And there are also guides for our Smart Checkout.

Prerequisites

As a prerequisite, you should understand:

Create a Smart Transaction

The API endpoint to create a Smart Transaction is POST /api/v2/Smart/Transactions.

Request
POST /api/v2/Smart/Transactions HTTP/1.1
Host: connect-testing.secuconnect.com
Authorization: Bearer qb56tjj1bcvo9n2nj4u38k84lo
Content-Type: application/json
Accept: application/json

"is_demo": true,
"intent": "sale",
"contract": {
"id": "GCR_KTSST836QYITQJM1JGYIZ4F4OLKI04"
},
"customer": {
   "contact": {
"forename": "Max",
"surname": "Mustermann",
"salutation": "Mr.",
"address": {
"street": "Max-Muster-Str.",
"street_number": "25a",
"additional_address_data": "Whg. 202",
"postal_code": "09555",

"country": "DE"
},
"email": "max@example.net",
"mobile": "+491775555555",
"phone": "+495555555555"
}
},
"transactionRef": "Bestellung am 25.02.21 bei Example.com",
"merchantRef": "20000345",
   "basket": {
"products": [
{
"id": 1,
"articleNumber": 30037,
"ean": "4999012345678",
"desc": "Höhenverstellbarer Schreibtisch",
"quantity": 1,
"priceOne": 49800,
"tax": 19
},
{
"id": 2,
"item_type": "shipping",
"desc": "Versand Spedition",
"quantity": 1,
"priceOne": 3500,

}
]
},
"basket_info": {
"sum": 54300,
"currency": "EUR"
},
  "payment_context": {
"auto_capture": true
}
}

This creates a demo transaction to sell a desk. The total amount is €543.00. The auto_capture setting saves an additional API call, if it fits the flow.

If everything is fine, the API responds with 200 OK and a representation of the newly created Smart Transaction:

Response
HTTP/1.1 200 OK
