This documentation provides a reference to the retrieveLineItem method. This belongs to the Cart Module.
You should only use this methods when implementing complex customizations. For common cases, check out available workflows instead.
</Note>This method retrieves a line item by its ID.
A simple example that retrieves a line item by its ID:
const lineItem =
await cartModuleService.retrieveLineItem("cali_123")
To specify relations that should be retrieved:
:::note
You can only retrieve data models defined in the same module. To retrieve linked data models from other modules, use Query instead.
:::
const lineItem = await cartModuleService.retrieveLineItem(
"cali_123",
{
relations: ["cart"],
}
)
