Authorization (optional)

Optional. 'Bearer <Postly API key>' for send_letter, get_letter_status, list_letters and get_balance (prepaid business account). Without a key, get_pricing, create_letter_order and get_order_status work and return a Stripe Checkout link a person must pay.

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

create_letter_order

Opretter et fysisk tekstbrev i Danmark og returnerer et betalingslink. Brugeren skal selv åbne linket og betale; brevet sendes først, når betalingen er gennemført. Kræver ingen API-nøgle. Bekræft altid modtagerens adresse og prisen med brugeren først.

textstring, required

Brevets tekst.

senderstring, required

recipientstring, required

letterTypestring, required

customerEmailstring

Valgfri e-mail til kvittering.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.
