## Operations (7)

- [Add a line to a shipment](https://developer.yoprint.com/reference/shipment-line-items/v2-shipment-item-create.md): `POST /v2/api/store/{team_slug}/v2/shipment/{unique_key}/item`. Adds one line to a shipment and recalculates it.
- [Add, change and remove shipment lines at once](https://developer.yoprint.com/reference/shipment-line-items/v2-shipment-item-bulk.md): `POST /v2/api/store/{team_slug}/v2/shipment/{unique_key}/item/bulk`. Applies several line changes to one shipment in one transaction: all of them are saved, or none.
- [List the lines of a shipment](https://developer.yoprint.com/reference/shipment-line-items/v2-shipment-item-index.md): `GET /v2/api/store/{team_slug}/v2/shipment/{unique_key}/item`. Returns every line of a shipment: shipped order lines and shipping cost lines.
- [Get a shipment line](https://developer.yoprint.com/reference/shipment-line-items/v2-shipment-item-show.md): `GET /v2/api/store/{team_slug}/v2/shipment/item/{unique_key}`. Returns one shipment line: `product` (for `order_item`, `_meta.parent` holds the order line), `pricing`, `quantity`, `weight`, `position` and `lock_version`.
- [Fix up shipment line positions](https://developer.yoprint.com/reference/shipment-line-items/v2-shipment-item-sort.md): `POST /v2/api/store/{team_slug}/v2/shipment/{unique_key}/item/sort`. Makes room around a line whose position you just changed, so positions stay unique and spaced.
