Making a test payment

Get a feel for how Barion works by using the Barion Gateway API to

1. set up a payment for the Barion shop you’ve created, and
2. 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

1. 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.

Step result: The API request returns the following JSON:

    {
      "PaymentId": [the payment ID generated for the transaction],
      "PaymentRequestId": "DEV-TEST-187",
      "Status": "Prepared",
      "QRUrl": "https://api.test.barion.com/qr/generate?paymentId=[the payment ID generated for the transaction]",
      "Transactions": [
        {
          "POSTransactionId": "DEV-TEST-01-01",
          "TransactionId": "[the payment ID generated for the transaction]",
          "Status": "Prepared",
          "Currency": "EUR",
          "TransactionTime": "0001-01-01T00:00:00",
          "RelatedId": null
        }
       ], 
      "RecurrenceResult": "None", 
      "ThreeDSAuthClientData": null, 
      "GatewayUrl": "https://secure.test.barion.com/Pay?Id=2[the payment ID generated for the transaction]", 
      "RedirectUrl": "http://barion.com/?paymentId=[the payment ID generated for the transaction]",
      "CallbackUrl": "",
      "TraceId": null, 
      "Errors": [] 
  }
