Cancel a payment

If you have authorised a payment but do not want to capture it, you need to make a Cancel request to release the funds back to the shopper. If the payment has already been captured, you need to refund it instead.

Make an API call to cancel a payment

Prerequisites

It is required that the payment has one Authorization transaction with state Success. From this transaction, the interactionId field is being used as originalReference for the Adyen cancel request.

Steps

To make a cancellation, add a transaction with type CancelAuthorization and state Initial to the commercetools payment.

{
  "action": "addTransaction",
  "transaction": {
    "type": "CancelAuthorization",
    "amount": {
      "currencyCode": "EUR",
      "centAmount": 500
    },
    "state": "Initial"
  }
}

Extension module will update the commercetools transaction with Pending transaction state and interactionId field with value pspReference from the Adyen response:

{
  "id": "a4504b99-d46e-484e-1344-ee4c3b6de1a2",
  "type": "CancelAuthorization",
  "amount": {
    "type": "centPrecision",
    "currencyCode": "EUR",
    "centAmount": 500,
    "fractionDigits": 2
  },
  "interactionId": "883592922122044H",
  "state": "Pending"
}

Request/response between Adyen and extension module are stored in interfaceInteraction field of the payment with type cancelPayment. The commercetools payment representation after a successful CancelAuthorization request:

{
  "id": "ca068e31-c2f1-410a-912d-d12bf3c645b2",
  "key": "14",

      },
      "interactionId": "853605802634337B",
      "state": "Pending"
    }
  ],
  "interfaceInteractions": [
    {
      "type": {
        "typeId": "type",
        "id": "5d93411a-9736-43ba-9f4d-5f14158427ba"
      },
      "fields": {
        "createdAt": "2020-11-19T16:17:14.247Z",
        "response": "{\"pspReference\":\"853605802634337B\",\"response\":\"[cancel-received]\"}",
        "request": "{\"originalReference\":\"883605782632488F\",\"merchantAccount\":\"YOUR_MERCHANT_ACCOUNT\"}",
        "type": "cancelPayment"
      }
    }
  ]
}

Additional information

  1. The amount field in the transaction is ignored. Adyen doesn't require the amount to be provided as cancellation could be done only for the whole amount.
  2. Technical cancel is not supported.
