    "county": "Lothian",
    "postcode": "BH23 6AA",

  "customerFirstName": "John",
  "customerId": "Customer001",
  "customerLastName": "Smith",
  "customerOrderCode": "ABC123",

}

📘

A Trustly accountId can be passed in the payment request for an optimised user experience.

You should expect to receive a response similar to the following:

{
  "code": "2101",
  "message": "Pending",
  "id": "684fe672a1c518af6d4e087f1c704759",
  "paymentId": "99082428-491d-407b-b6d2-8559bc17f4b1",
  "actionRequired": true,
  "action": {
    "type": "REDIRECT",
    "paymentId": "99082428-491d-407b-b6d2-8559bc17f4b1",
    "data": {
      "providerTransactionId": "13082384720",
      "url": "https://checkout.test.trustly.com/checkout?OrderID=13082384720&SessionID=89f48989-c314-45dd-9a4f-5a65361f15b7"
    }
  },
  "psp": {
    "name": "Trustly",
    "transactionId": "13082384720"
  },
  "pspId": "TRUSTLY",
  "customerOrderCode": "ABC123"
}

The link returned in the action.data.url field should be used to redirect the payer to complete the payment.

Refund Request

To refund a Trustly payment, use the paymentId returned in the /v1/payments response.

Pass the paymentId as a path parameter to the /v1/payments/{paymentId}/refund endpoint to process a Trustly refund.

You should expect to receive a response similar to the following

{
  "code": 1000,
  "message": "Approved",
  "id": "4fad8e2e06a15656",
  "psp": {
    "name": "Trustly",
    "transactionId": "a83a53a2-dcc8-45be-bf70-2b1e4b719f7c"
  }
}

Payout Request

Payouts with Trustly can be performed via the BR-DGE /v1/payouts endpoint. You must provide a Trustly accountId when executing a Trustly payout.

A Trustly accountId can be obtained in different ways:

• The accountId will be sent after a payment via a paymentInstrument.accountSelection notification.
• The accountId can also be retrieved from a previous Trustly payment by querying the /v1/payments/{paymentId}/status endpoint
• If the customers bank account details are not available, use the /v1/payment-instrument-verifications endpoint to obtain an accountId.
  The accountId will be sent via a paymentInstrument.accountSelection notification.
• If you have the customers bank account details, use the /v1/payment-instrument-registrations endpoint to obtain an accountId.
  The accountId will be sent via a paymentInstrument.accountRegistration notification.

To perform a Trustly payout via BR-DGE, send a /v1/payouts request with the accountId specified in the paymentInstrument object

📘

The customerId from the Verify Account and Register Account steps should be the same passed as the customerId in the payout call..

{
    "psp": "trustly",
    "amount": 1,
    "paymentInstrument": {
        "type": "trustly",
        "accountId":"1891084940"
    },
    "currencyCode": "GBP",
    "recipient": {
        "firstName": "John",
        "ipAddress": "123.100.100.200",
        "lastName": "Smith",
        "customerId": "sampleId"
    },
    "reference": "reference",
    "purpose": "boats"
}

You should expect to receive a response similar to the following

{
    "code": "2101",
    "id": "6842ed46e4b3aee763ad9294ec1784ca",
    "message": "Pending",
    "paymentId": "1d64bed0-45e1-4669-854c-5e114fe72a93",
    "psp": {
        "name": "Trustly",
        "transactionId": "13019197993"
    }
}

📘

The synchronous response will always be “Pending”. The status of the payout will be updated asynchronously.

Register Account

Once you have the customers bank account details you want to make the payout to, send a request to the BR-DGE /v1/payment-instrument-registrations endpoint with the mandatory fields.

This step is used to register a bank account that is not already registered with Trustly.

Validation of the bank account details is your responsibility as the merchant.

{
  "type": "trustly",
  "customer": {
    "customerId": "customerId",
    "firstName": "Steve",
    "lastName": "Smith",
    "country": "GB",
    "postcode": "BH23 6AA",
    "town": "Edinburgh",
    "addressLine1": "Main street 1",
    "addressLine2": "Main street 2",
    "phoneNumber": "+46709876543",
    "email": "[email protected]",
    "dateOfBirth": "1990-02-19"
  },
  "bank": {
    "bankNumber": "200052",
    "clearingHouse": "UNITED_KINGDOM",
    "accountNumber": "75849855"
  }
}

You should expect to receive a response similar to the following.

{
    "type": "trustly",
    "code": "1004",
    "message": "Request succeeded",
    "id": "6842ecf2c7ca5e17718458b64fc12aab",
    "paymentInstrumentRegistrationId": "cc6bf638-7940-4a71-bc99-64e5426d5666",
    "accountId": "1891084940",
    "clearingHouse": "UNITED_KINGDOM",
    "bank": "Barclays Bank",
    "descriptor": "**849855"
}

📘

Where the accountId from a Register Account response is used in a payment request, the customer will not enter an Express Checkout flow.

Account Verification

Where the customers bank account details are not available and you want the customer to select the account the payout should be made to, send a request to the BR-DGE /v1/payment-instrument-verifications endpoint with the mandatory fields.

{
    "psp": "Trustly",
    "verificationDetails": {
        "type": "trustly",
        "firstName": "John",
        "lastName": "Smith",
        "customerId": "def456",
        "country": "GB",
        "locale": "en_GB",
        "email": "[email protected]",
        "ipAddress": "123.100.100.200",
        "documentId": "ABC-123456",
        "phoneNumber": "+44 123 1110000",
        "dateOfBirth": "2000-01-01"
    }
}

You should expect to receive a response similar to the following

{
    "id": "68498e0d66bc216d193e24b3b61bd5c0",
    "verificationId": "1affcb97-a71f-4714-aada-49e971d9aa13",
    "psp": "Trustly",
    "code": "2101",
    "message": "Pending: The operation has been accepted for processing and the outcome is not yet known",
    "verificationResult": {
        "type": "trustly",
        "actionRequired": true,
        "action": {
            "type": "REDIRECT",
            "data": {
                "url": "https://checkout.test.trustly.com/checkout?OrderID=13954400995&SessionID=3c764f4d-b611-4519-b8c8-f717ae300b4f"
            }
        }
    }
}

📘

The link returned in the redirectUrl field should be used to redirect the customer to select the account they wish to complete the payout with.

{
    "type": "trustly",
    "code": "1004",
    "message": "Request succeeded",
    "id": "6842ecf2c7ca5e17718458b64fc12aab",
