**1. Request initiation.**

* An SME business cardholder or the issuer initiates a request using the unique `orderId`.

**2. Retrieve redemption details.**

## Use case examples {#use-case-examples}

### Retrieve lost voucher code {#retrieve-lost-voucher-code}

An SME business cardholder previously unlocked an offer but misplaced the voucher code required for redemption on the merchant's website. The issuer uses the `orderId` to retrieve the voucher code and associated redemption instructions. The issuer re-shares this information with the SME business cardholder to complete the redemption process.

### Customer support verification {#customer-support-verification}

An SME business cardholder submits a support request, claiming they redeemed an offer but did not receive the expected benefit. The support team uses the `orderId` to retrieve the redemption record. They verify the voucher code, its validity, and redemption instructions to troubleshoot the issue and assist the SME business cardholder effectively.
