## What are transaction items?

Transaction items are attached to a [transaction](ref:transactions) and contain pricing information that pairs with the accompanying transaction. Additional items can be added to an existing transaction by using the [Add Transaction](/api-reference/transaction/add-transaction) endpoint, or directly when creating the transaction with [Add Transaction](/api-reference/transaction/add-transaction).

## Embedded transaction and location

When a transaction item response includes the parent `transaction` object, the transaction embedding also includes a `location` object if the transaction has an associated [location](/concepts/commerce/locations). The `location` object contains the location's `id`, `type`, `name`, `description`, `phone`, `email`, `external_id`, `is_published`, `is_permanently_closed`, and nested `address`.
