Merchants can void (cancel) transactions during the short time window between submitting the transaction request and the moment Nuvei passes the Sale/Credit/APM transmission. For example, in the best-case scenario, voiding a transaction might only be possible within 24 hours after submitting the transaction request.

To void a previous transaction using Nuvei REST API 2.0, merchants can send a POST request to one of the following endpoints using the paymentId for the original payment transaction:

• To void a payment or an authorization:  /payments/{payment-id}/voids
• To void a settlement: /payments/{payment-id}/settles/{settle-id}/voids
• To void a refund: /payments/{payment-id}/refunds/{refund-id}/voids

Include the mandatory parameters for the request.

If the merchant needs to cancel a void transaction, attach /{void-id}/voids to the appropriate endpoint. For example, to cancel a void transaction for a payment, send a POST /payments/{payment-id}/voids/{void-id}/voids request with its mandatory parameters.

Example POST payments/{payment-id}/voids Request

{
  "processingEntityId": "<your processingEntityId>"
}
