Record a customer payment on an open invoice.

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

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

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

Clicks Zahlung erfassen on the invoice with the amount, the payment date and the payment type. The invoice drops out of the open and overdue lists once the open amount is paid. A payment recorded by hand is removed with the trash icon in the invoice details, but users with the restricted role "Belege, Kontakte & Produkte" cannot delete payments. By default you confirm each call; you can switch that off for this tool.

| `amount` | number | yes | Amount received in EUR. |

## 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.
