An array of line items on the Payable. If you don't wish to make any changes to the Payable's line items,
omit this value from your payload entirely.
If you send line_items on the payload:
- To keep a single line item unchanged: Include a JSON object in the array containing just the line
item's ID.
- To add a new line item: Include a JSON object in the array, without an ID, containing all of the
required properties for a line item. See the Create Payable documentation for more details.
- To edit a line item: Include a JSON object in the array, with the line item's ID, and any line item
properties you wish to change. See the Create Payable documentation for a list of available properties.
- To delete a line item: Submit a payload which includes a line_items array, but omit the line item from
the array submitted. You may not delete the last line item on a Payable.
