Book a draft invoice, and optionally send it by email or EAN.

e-conomic API: https://cotlet.dev/docs/api/e-conomic.md

`POST https://cotlet.dev/api/v1/e-conomic/draft-invoices/{draft_invoice_number}/invoices`

Access: write. Confirm: waits for the user's OK before it runs.

Books the draft, which gives it an invoice number, and a booked invoice cannot be edited any more. With send_by email or ean, the invoice is sent to the customer after booking, and only if booking succeeds. Without it nothing is sent. An EAN invoice needs your CVR and country in master data and a recipient identifier on the customer. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `draft_invoice_number` | integer | yes | Draft invoice number from list_draft_invoices or create_draft_invoice. |
| `send_by` | string | no | none, email or ean. Default: none. |
| `book_with_number` | integer | no | Own invoice number. Default: next number in the sequence. |

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
