Lines WITH line_id update existing lines. Lines WITHOUT line_id are ADDED as new. Lines NOT included are KEPT unchanged. To 'delete' a line, you must include ALL existing lines with their line_ids and set unwanted lines to amount: 0. Line amounts must sum to the original deposit total (use expected_total to override for corrupted deposits).

Create a bill payment (the QBO 'check' / 'pay bills' flow). Pays one or more existing bills and optionally applies vendor credits, clearing Accounts Payable.
