# List cart promotions (/api/carts/list-cart-promotions)

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

Lists the promotions applied to the cart: its coupon, and the cross-sell and up-sell offers of its items. An offset-based list. `sort_by` takes `date_created` (the default), `promotion_id`, `name` or `date_modified`. Any token type may call it; a limited token only for a bound cart.

## Parameters

- `cart_id` (path, required): The id of the cart.
- `active` (query): `true` for active promotions only, `false` for inactive only.
- `q` (query): Search text. Matches a promotion_id exactly or part of a promotion name.
- `limit` (query): How many items to return on one page, from 1 to 100. The default is 100. A value outside 1 to 100, or one that is not a whole number, is a `400`.
- `offset` (query): For offset-based lists, how many items to skip before the page starts. Use `next_page_offset` or `previous_page_offset` from the page you have. A value that is not a whole number is a `400`.
- `sort_by` (query): The field to sort by. Any other value sorts by `date_created`.
- `desc` (query): Sort in descending order (newest, largest or last first) when `true`. The default is `false`. A value other than `true` or `false` is a `400`.
- `show` (query): Comma-separated fields to return; all others are left out. Use dot notation for child fields (`customer.email`). You cannot send `show` and `hide` together (`400`). See [Customizing output](https://docs.comecero.com/docs/basic-concepts/customizing-output).
- `hide` (query): Comma-separated fields to leave out of the response. Use dot notation for child fields (`customer.email`). You cannot send `show` and `hide` together (`400`). See [Customizing output](https://docs.comecero.com/docs/basic-concepts/customizing-output).
- `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`). The default is `false`. See [Localized formatting](https://docs.comecero.com/docs/basic-concepts/localized-formatting).

Responses: 200, 400, 401, 403, 404, 500.
