Intervals API Resource: invoiceitem

The base URL for this resource is located at
https://api.myintervals.com/invoiceitem/

Invoice line items can either be created automatically upon invoice creation (in the case of prefilled invoices) or they can be user generated (in the case of freeform invoices, or line items added to prefilled invoices). You can tell the difference by reading the custom field value, which will be true in the case of user generated line items and false in the case of line items that were generated automatically.

For custom line items, you may edit any field value. For non-custom line items, however, the only editable field is the description field. Furthermore, non-custom line items are not deletable by any level of user. This is done to ensure that a project and its invoices always match up.
