**gateway**

The 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.

## Recommended Customer Message

We are unable to issue a credit since the transaction does not meet the expected criteria. Kindly reach out to customer support for further assistance.

## Root Cause[](#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[](#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.
