# Get a promotion (/api/promotions/get-promotion)

`GET https://api.comecero.com/api/v1/promotions/{promotion_id}`

- `formatted` (query): When `true`, the object also has a `formatted` child with amounts and dates as display text in the shopper's language and currency (for example `$19.99` or `November 7, 2026`).
