List of ErrorsThe transaction could not be processed because the payment has already been captured. This happens when a duplicate capture attempt is made, the payment workflow logic caused a retry on a completed transaction, or delayed acknowledgments resulted in repeated capture attempts.

Root Cause

• Duplicate capture attempt: The system attempted to capture funds for a transaction that has already been successfully captured.
• Incorrect transaction workflow: Your system retried a capture on a completed transaction due to an error or misconfiguration.
• Delayed response handling: A delayed acknowledgment from the payment gateway caused a repeated capture attempt.
• Manual capture already processed: The transaction was previously captured manually, but the system initiated another capture automatically.

Troubleshooting and Solutions

• Verify the transaction records to confirm that the payment has already been successfully captured.
• Inform the customer that the payment was processed successfully and no further action is required.
• Prevent duplicate capture attempts by reviewing and correcting the payment workflow logic.
• Contact your payment gateway support if system-level retries or delayed acknowledgments are causing repeated captures.
• Implement safeguards to ensure transactions marked as captured are not processed again.
