Adyen code 06 – Error

The payment could not be authorized and resulted in an error. The shopper can try again or use another payment method.

What does Adyen refusal code 06 mean?

Adyen refusal code 06 Error is a generic technical error response. Something failed somewhere along the processing path — at the acquirer, network, or issuer — and the transaction could not complete. It isn't a deliberate refusal, which is why retries frequently succeed.

Is it a soft or hard decline?

Code 06 is a soft decline. Because the root cause is a technical error rather than a cardholder decision, retrying after a short delay is often effective.

Common root causes

  • Transient issuer or network errors

  • Timeouts between the acquirer and issuer

  • Malformed transaction data caught by the issuer

  • Gateway or acquirer intermittent issues

Recommended recovery steps

  1. Retry after a short delay to let the upstream condition clear.

  2. Check for systemic patterns — if 06 spikes across many cards, a gateway or acquirer issue is likely.

  3. Review transaction formatting if 06 comes repeatedly on specific merchant endpoints.

How FlyCode handles Adyen code 06

FlyCode's ML models differentiate transient 06 errors (high retry success) from systemic ones (requires investigation), retrying the former automatically and flagging the latter in the dashboard. This prevents wasted retries during acquirer incidents while maximizing recovery when the error is truly transient.

Frequently Asked Questions

Is Adyen code 06 a soft or hard decline?

Should I retry Adyen 06?

Usually yes. Code 06 is technical, not a deliberate refusal, so a retry after a short delay often succeeds. If 06 rates spike across cards, check for a gateway or acquirer issue instead.

How does FlyCode handle Adyen code 06?

FlyCode's ML models classify 06 errors by signature, retrying transient ones automatically and surfacing systemic ones in the dashboard for inspection — minimizing wasted attempts.
