Buys and sends a letter that prepare_certified_letter prepared IN THIS CONVERSATION, after the person approved the exact total here. Call it only when (1) you have told the person the exact total, the recipient and the service, and they said yes to that total in this conversation, and (2) your platform has given you a Stripe shared payment token (spt_...) granted to Piloxa for that amount. Piloxa holds the payment, hands the letter to the printer, and charges only once the printer accepts it; if the printer refuses, the hold is released and nothing is charged. ALWAYS pass one idempotency_key per purchase and reuse it on every retry: the same key never charges twice and returns what already happened. If the total, the document or the address changed since the person approved, nothing is charged and you must ask again. Without a token, or if paying here is unavailable, nothing is charged and approval_url is returned: give it to the person, who pays there. The result carries transaction_state: AWAITING_APPROVAL, AUTHORIZED, VENDOR_ACCEPTED, MAILED, DELIVERED, RETURNED, FAILED or CANCELLED. Say a letter was sent only at VENDOR_ACCEPTED or later. At AUTHORIZED with failure OUTCOME_UNCERTAIN, do NOT retry: call get_certified_letter_status.
