purchase:write

Drafts a vendor bill with no VAT, matching the vendor by TRN and then by name, or creating it. Sending it again with the same vendor reference — or, for a bill with no reference, the same Idempotency-Key header — returns the first bill with duplicate: true. A bill with VAT is made from a purchase order: POST /api/v1/purchase-orders/{id}/bills.
