This causes the payment to be automatically denied by Adyen, and the order gets stuck in a failed state, even in cases where the charge was already processed on Adyen's side.\n\nAuthorization response:\n\n`{\"status\":409,\"errorCode\":\"704\",\"message\":\"request already processed or in progress\",\"errorType\":\"validation\"}`\n\nFollowing the message:\n\n`Not expected Response [].`\n\nBecause VTEX does not receive a successful authorization response, no settlement is triggered, and an automated refund cannot be issued.\n\n## Simulation\n\nUnable to reproduce. No consistent pattern has been identified to trigger the duplicate request.\n\n## Workaround\n\nNot available."}
