⚠️ The following is for reference only. The behavior may be different per country. For example, some countries only use cancellations, while others use a combination of cancellations and credit notes. Please refer to the country-specific documentation.

Here you can find up-to-date API documentation about this operation.

Clients can request a cancellation for a previously submitted transaction. The transaction is reported to the tax authorities when applicable and a cancellation document referencing the original invoice is generated if PDF generation is enabled.

To cancel a transaction, send the following HTTP request

POST api.fonoa.com/v1/transactions/cancellation with the following JSON body:

POST https://api.fonoa.com/v1/transactions/cancellation

{
  "country_code": "IE",
  "transaction_date": "2022-12-23T12:44:55Z",
  "transaction_id": "MY_CANCELLATION_TRANSACTION_ID",
  "reference_transaction_id": "MY_ORIGINAL_TRANSACTION_ID",
  "note": "This is my call to action for <b>cancelling</b> a transaction."
}

The original transaction is referenced by transaction_id provided by the client at the time of submission.

The rest of the flow is the same.
