List of ErrorsThe refund could not be issued because the original transaction is not eligible for a refund. This can occur when the transaction is not yet settled, when there are gateway restrictions, or when required transaction details are missing or invalid.

Root Cause

• Transaction not eligible for refund: The original payment might not be settled, captured, or fall outside the refundable parameters.
• Gateway restrictions: The payment processor has rules preventing credits in specific scenarios (e.g., chargebacks in progress, expired refund windows).
• Incorrect refund logic: The refund request does not align with the gateway's expected flow (e.g., refund amount mismatch, currency issues).
• Missing transaction details: Required identifiers or metadata for refunding may be incomplete or invalid.

Troubleshooting and Solutions

• Inform the customer that a credit could not be issued for their transaction due to unmet eligibility criteria.
• Verify the original transaction status (e.g., captured, settled).
• Check the gateway documentation or support to identify refund requirements and limitations.
• Ensure all refund request parameters (amount, reference ID, currency) are accurate.
• If necessary, retry the refund after resolving the identified issue or offer alternative solutions such as store credit or offline reimbursement.
