# List approved devices

> List the Approved Product List (APL) entries for a program: the catalog devices it pays a rebate on. Each entry names the catalog `device_id`, the tier it is bound to when it is tier-specific, and the APL publication it came from. Resolve a `device_id` with **Search device catalog**.
