Webhook structure and types

Learn which webhook types are sent for each event.

Each webhook payload contains an eventCode that specifies the type of event triggered. Some eventCodes are enabled in Standard webhooks by default, and some need to be enabled.

In addition to the Standard webhook, you can also receive other types of webhooks.

Webhook structure

Each webhook event contains the following fields:

  • live: Specifies whether the event happened on the test or live environment.
  • notificationItems: An array of NotificationRequestItem objects.

    JSON and HTTP POST webhooks contain only one NotificationRequestItem object in the notificationItems array. SOAP webhooks may contain up to six NotificationRequestItem objects, in case the events happen within a very short period of time.

The notificationItems object contains information about the event:

  • additionalData: Additional information about the shopper or the transaction. For more information about the fields that you can receive in additionalData, refer to Additional settings.
  • eventCode: The type of event. For a list of possible eventCode values, refer to Event codes.
  • success: The outcome of the event, set to either true or false.

    For some event codes, such as REPORT_AVAILABLE, the success field is always set to true.

  • eventDate: The time of the event. Format: ISO 8601; YYYY-MM-DDThh:mm:ssTZD

Some fields included in the NotificationRequestItem object depend on the type of event triggered. For example, webhook events triggered by a request to refund a payment include:

  • originalReference: The pspReference of the original payment.

For more information about the fields included in specific webhook events, refer to Event codes.

Event codes

Adyen sends the Standard webhook with Default event codes that can't be disabled. You can also enable additional non-default event codes.

Because we sometimes create new webhook types and event codes, you should set up your server to be able to accept webhooks of more types and receive more event code values than are listed below. When we create a new event code, you have to create new business logic if you want to use it.

Default event codes

By default, the Standard webhook includes the following eventCode values. There are different categories of event codes:

Transaction events

eventCode Description
AUTHORISATION

The success field informs you of the outcome of a payment request.

For payment methods that return an immediate authorisation result, such as cards, you will also receive an AUTHORISED webhook event.

Although you can use the payment result from the API, we recommend that you rely on the webhook to trigger any business logic to make sure that your system is able to handle both synchronous and asynchronous payment flows.

AUTHORISATION_ADJUSTMENT

The success field informs you of the outcome of a request to adjust the authorised amount.

The originalReference field contains the pspReference of the original payment.

CANCELLATION

The success field informs you of the outcome of a request to cancel a payment.

The originalReference field contains the pspReference of the original payment.

CANCEL_OR_REFUND

The success field informs you of the outcome of a request to cancel or refund a payment.

The originalReference field contains the pspReference of the original payment.

CAPTURE

The success field informs you of the outcome of a request to capture a payment.

The originalReference field contains the pspReference of the original payment.

By default, the CAPTURE webhook is not sent for automatic captures. If you are using delayed automatic capture, you must also enable this event code on the Webhooks settings page.

CAPTURE_FAILED

The capture failed due to rejection by the card scheme.

The originalReference field contains the pspReference of the original payment.

Technical failures are automatically re-captured by Adyen within 10 business days.

You can simulate this webhook event by following our guide on testing failed modifications.

EXPIRE

The original payment has expired on the Adyen payments platform.

The success field is always true because the payment expired on the Adyen payments platform.

The amount field contains the details of the original payment.

For more information, refer to Expiration of authorizations.

HANDLED_EXTERNALLY

The payment has been handled outside the Adyen payments platform.

ORDER_OPENED

Sent when the first payment for your payment request is a partial payment, and an order has been created.

ORDER_CLOSED

The success field informs you of the outcome of the shopper's last payment when paying for an order in partial payments. Possible values:

  • true: The full amount has been paid.
  • false: The shopper did not pay the full amount within the sessionValidity. All partial payments that were processed previously are automatically cancelled or refunded.

  • REFUND

    The success field informs you of the outcome of a request to refund a payment.

    The originalReference field contains the pspReference of the original payment.

    Possible values:

  • true: The refund request was successful.
  • false: The refund request failed due to a technical issue

  • REFUND_FAILED

    The refund failed due to a rejection by the card scheme.

    The originalReference field contains the pspReference of the original payment.

    You can simulate this webhook event by following our guide on testing failed modifications.

    REFUNDED_REVERSED

    The refunded amount has been returned to Adyen, and is back in your account.

    The originalReference field contains the pspReference of the original payment. For more information, refer to Failed refund.

    REFUND_WITH_DATA

    The success field informs you of the outcome of a request to refund with data.

    REPORT_AVAILABLE

    A new report is available. The reason field contains the URL where you can download the report, and the pspReference field contains the name of the report.

    VOID_PENDING_REFUND

    The success field informs you of the outcome of a request to cancel an unreferenced POS refund.

    The originalReference field contains the pspReference of the original payment.

    You won't receive a webhook event when a payment is settled.

    Dispute events

    eventCode Description
    CHARGEBACK A payment was charged back, and the funds were deducted from your account.
    CHARGEBACK_REVERSED A chargeback has been defended towards the issuing bank. This stage is not final. If the issuing bank decides to present a second chargeback, you might still lose the chargeback case.
    NOTIFICATION_OF_CHARGEBACK The dispute process has opened. You should investigate the dispute and supply defense documents.
    NOTIFICATION_OF_FRAUD The alert passed on by issuers to schemes and subsequently to processors. Visa calls them TC40 and Mastercard calls them System to Avoid Fraud Effectively (SAFE). These are informational webhook events offered at no charge by Adyen, providing you the opportunity to take action, such as blocking a shopper or issuing a refund before a chargeback is incurred.
    PREARBITRATION_LOST Your pre-arbitration case has been declined by the cardholder's bank.
    PREARBITRATION_WON Your pre-arbitration case has been accepted by the cardholder's bank.
    REQUEST_FOR_INFORMATION A shopper has opened an RFI (Request for Information) case with the bank. You should supply defense documents to help shopper understand the charge.
    SECOND_CHARGEBACK The issuing bank declined the material submitted during defense of the original chargeback. The disputed amount is deducted from your account.

    Payout events

    eventCode Description
    PAYOUT_EXPIRE The payout has expired.
    PAYOUT_DECLINE The user reviewing the payout declined it.

  • true: The request was successful.
  • false: The request failed. The reason field contains a short description of the problem.
  • PAIDOUT_REVERSED The financial institution rejected the payout. We will return the funds back to your account. The reason field contains the bank statement description if present.
