Limitations

The following features are not supported by this connector:

  • Void - Canceling an authorization is not available
  • Payment method tokenization - Storing payment methods for recurring transactions is not supported

  • Over-capture - Capturing more than the authorized amount is not supported
  • Partial authorization - Authorizing only a portion of the requested amount is not supported

​
Captures and refunds

As Sofort transactions can take up to 48 hours to be marked as paid, refunds cannot be processed until the transaction reaches that state. Transactions marked as Captured in the system might not be refundable until this point.

​
Integration

The default integration for Sofort via TravelHub uses a redirect to a payments page hosted by Gr4vy. Start by creating a new transaction with the following required fields. 
var transaction = await client.Transactions.CreateAsync(
	transactionCreate: new TransactionCreate()
	{
		Amount = 1299,
		Currency = "EUR",
		Country = "DE",
		PaymentMethod =
			TransactionCreatePaymentMethod.CreateCheckoutSessionWithUrlPaymentMethodCreate(
				new RedirectPaymentMethodCreate()
				{
					Method = "sofort",
					RedirectUrl = "https://example.com/callback",
				}
			),
	}
);
After the transaction is created, the API response includes payment_method.approval_url and the buyer_approval_pending status. 
{
	"type": "transaction",
	"id": "ea1efdd0-20f9-44d9-9b0b-0a3d71e9b625",
	"payment_method": {
		"type": "payment-method",
		"approval_url": "https://cdn.sandbox.spider.gr4vy.app/connectors/worldline/apm.html?token=..."
	},
	"method": "sofort"
}
Redirect the buyer to the approval_url (open in a browser or Webview) so they can complete authentication and approve the payment. After approval, the buyer is redirected to the redirect_url you provided when creating the transaction. Do not rely solely on the redirect - either poll the transaction or (recommended) rely on webhooks to detect the final status (for example capture_succeeded or failure states).
