Fetch a proposal alternative

Returns one alternative on a proposal, with the IDs of the packages in it. GET /api/v1/events/{event_id}?include=proposal_alternatives lists every alternative on a proposal.

sub_total, tax_amount, final_total and deposit_amount_due price this alternative on its own, the way the client sees it on the proposal. They are null without assigned_event_read_pricing or unassigned_event_read_pricing.

Use the include query parameter to sideload related resources (comma-separated). Available: event_bookings, event_adjustments. event_adjustments lists the adjustments, such as travel fees and discounts, that apply to this alternative.

Required permission: assigned_event_read or unassigned_event_read
