Adyen code 00 – Cancelled
The transaction was canceled after being initially approved by the issuer. This can occur for various reasons, such as the shopper returning goods after purchase.
What does Adyen refusal code 00 (Cancelled) mean?
The Adyen code 00 labelled Cancelled is returned when an authorization was completed successfully but then cancelled before capture — either by the shopper, the merchant, or by a system timeout on Adyen's side. It is not a decline by the issuing bank; it's a status indicating the transaction flow was interrupted after approval.
Is it a soft or hard decline?
This is classified as a soft decline. The card and account are valid, and the authorization itself succeeded. Whether to retry depends on why the cancellation happened.
Common root causes
The shopper cancelled the checkout before completion
A 3-D Secure session timed out
The merchant's system cancelled the auth due to an inventory or fraud check
Adyen itself timed out waiting for a downstream callback
Recommended recovery steps
Check if cancellation was intentional. If the shopper deliberately cancelled, do not retry.
Retry system-caused cancellations. Timeouts and technical cancellations are strong retry candidates.
Investigate recurring patterns. If the same customers see many 00 cancellations, there may be a checkout UX issue.
