Description
A duplicate transaction has been submitted. Authorize.net checks for identical transactions submitted within a two-minute window based on amount and card information.
Recommended Action
Wait at least 2 minutes before retrying, or change the transaction details. Use invoice numbers to differentiate legitimate transactions.
Common Causes
- Same amount and card info submitted within 2 minutes
- User double-clicked the submit button
- Retry logic fired too quickly after a timeout
Recovery Tips
- Implement idempotency in your payment flow
- Use unique invoice numbers for each transaction attempt
- Add a minimum 2-minute delay between retries of the same card
