Email a finalised invoice or quote to the customer with its PDF attached.

Lexware Office (lexoffice) API: https://cotlet.dev/docs/api/lexware-office.md

`POST https://cotlet.dev/api/v1/lexware-office/documents/{document_id}`

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

Sends the finalised document from your own sender address with your email text template, to the email address saved on the contact or the one you pass. A draft cannot be sent. The customer receives it at once. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `document_id` | string | yes | Document ID from list_documents or create_invoice. |
| `to` | string | no | Recipient email. Default: the email saved on the contact. |
| `message` | string | no | Email text. Default: your saved email text template. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

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.
