Making a test payment
Get a feel for how Barion works by using the Barion Gateway API to
- set up a payment for the Barion shop you’ve created, and
- settle the payment with some test money from your Barion Wallet.
Prerequisites
- Completing the first part of this tutorial.
- An API testing tool such as Postman
Make a test payment using the Barion API
1. Log in to to your Barion shop.
2. Click through to Shops>Actions>Details>Secret Key (POSKey), and copy the value to the clipboard. 
Finding your shop’s POSKey
3. Start the Postman Desktop agent, and make a POST call to https://api.test.barion.com/v2/payment/start, passing the following JSON in the request body: Replace the POSKey and the Transactions/Payee as indicated.
{
"POSKey": "[the POSKey you've just copied]",
"PaymentType": "Immediate",
"PaymentRequestId": "DEV-TEST-615",
"FundingSources": ["All"],
"OrderNumber": "Order_01",
"RedirectUrl": "https://example.com/",
"Currency": "EUR",
"Locale":"en-US",
"GuestCheckOut": true,
"PaymentWindow":"00:30:00",
"Transactions": [
{
"POSTransactionId": "DEV-TEST-01-01",
"Payee": "[the email address associated with the Barion shop]",
"Total": 100,
"Comment": "Test transaction",
"Items": [
{
"Name": "Nada",
"Description": "Zilch",
"Quantity": 1,
"Unit": "db",
"UnitPrice": 1,
"ItemTotal": 1,
"SKU": "SM-01"
}
]
}
]
}For details on the various parameters you’re passing in the call, see the Payment/Start API endpoint reference.
