The clock

set per card scheme, and shown as days left

Adyen publishes no single number: the defence window is set by the scheme in calendar days and varies by dispute reason. On some reasons — services not provided, merchandise not received, goods not as described, credit not processed — the clock starts from the expected delivery date, not the transaction date. The Disputes page shows the exact days remaining.

reason code, as Adyen shows it

Yes, plainly — the dispute page shows the reason and the reason code. Adyen is the best of these for knowing exactly what you are answering.

What Adyen does for you

  • yesAuto-defends chargebacks that need no argument: already refunded, 3-D Secure liability shift, out of timeframe, wrong merchant category.
  • yesShows the reason and reason code, the creation date, the days left, and whether it was auto-defended.
  • yesOffers an API endpoint for uploading defence documents if you would rather not click.

What it leaves to you

  • noIt charges a fee on every booked chargeback and advises you only to defend where the evidence is compelling.
  • noLosing at scheme arbitration can add a fee of up to USD 600.
  • noOne document means one document: an unindexed pile is a lost dispute.

the common misreading

The clock may have started before the transaction date

On non-receipt and not-as-described reasons the window runs from the expected delivery date. Merchants count from the wrong day and file a defence that is out of time.
