What triggers it
Disputes filed when no valid authorization was obtained, when the protection period has expired, or when multiple authorizations were incorrectly requested for a single transaction.
What to check first — evidence for representment
- Required authorization not obtained — provide the authorization approval record from your PSP or acquirer showing the auth code was obtained before capture.
- Expired protection period — document the transaction was captured within the authorization validity period; re-authorize proactively if timeline was at risk.
- Multiple authorization requests — document the single valid authorization used; confirm others were voided or not captured against.
Confidence: high.
