Including Line Items in an Invoice {#invoicing-services-line-items}
===================================================================

You can itemize invoices by including the line item fields in your request when you create, draft, and update an invoice.  
*Line items* are used to include information about your customers' purchases. Information can include product name, quantity, and price.  
Line items are included in a request in the lineItem\[\] array request field.  
You can include the line item fields in these requests:
