## When to prefer this

Use this endpoint when you need to retrieve the list of vouchers available in the Loyal Spark loyalty platform, particularly within an agentic workflow managing loyalty rewards, customer incentives, or promotional offers. Prefer over the recipient-api/vouchers endpoint when accessing vouchers from an admin or program-management perspective rather than a recipient's perspective.

- 401/402 Unauthorized — payment not processed or credentials missing
- 404 Not Found — vouchers endpoint unavailable
- 500 Internal Server Error — upstream service failure
- Empty list returned if no vouchers are configured
