Create invoice
Create a draft invoice for a customer with its lines.
POST https://cotlet.dev/api/v1/bokio/customers/{customer_id}/invoices
write
Creates an invoice as a draft with status draft and no invoice number, and returns net, VAT and total so you can check them. Bokio has no discount per line: add a line with a negative unit price instead. A draft reaches no one and can be deleted in Bokio, so create_invoice runs without asking first; publishing is a separate tool.
