	Description		Read-only	Idempotent	Open world
`complete_checkout`After the buyer approves the prepared order and total, pay its existing checkout session using a compatible Stripe payment token, including a shared payment token (spt_...). Pass the order ID as checkout_session_id; do not resend the document or addresses. On an interrupted request, retry the same checkout and token. Existing authorized, processing, or paid payments are reused; follow the returned status and messages.

`postalform.create_form_order_draft`Prepare a supported workflow form for mailing and return the order ID, total, hosted checkout URL, and checkout session. After buyer approval, a compatible client can use complete_checkout with a Stripe shared payment token; otherwise present the hosted checkout URL. To prepare for MPP, set payment_protocol=mpp and buyer_email; receive a PDF preview, hosted checkout_url fallback and MPP challenge, then use postalform.pay_order with the order_id after buyer approval. Draft creation never pays. For x402, use postalform.create_machine_order.	Prepare a supported workflow form for mailing and return the order ID, total, hosted checkout URL, and checkout session.

`postalform.create_letter_order_draft`Prepare letter text for mailing and return the order ID, total, hosted checkout URL, and checkout session. Accepts text directly; no PDF upload or browser is needed. Letter drafts may include typed or drawn signatures.

`postalform.create_machine_order`Create a single PDF, letter, workflow-form order, or bulk letter campaign and pay through MPP or x402 after buyer approval. For bulk, provide exactly one of bulk.csv_content or bulk.recipients (JSON address objects with optional merge_fields), plus a shared PDF or text/HTML template. Omit top-level recipient fields and review campaign_url, recipient count and total. Bulk MPP orders can also use postalform.pay_order after fetching its challenge. The unpaid response also includes checkout_url and status_url for this same order. Without an available compatible wallet, give the buyer checkout_url and poll status_url; never recreate the order to change payment paths. Single-recipient clients with a Stripe shared payment token can instead use a draft tool followed by complete_checkout; other clients should present the hosted checkout URL.

`postalform.get_order_status`Read payment status and total, processing, stored mailing/carrier status, the latest 50 public tracking events, and electronic return receipt availability. Use payment_status_label and payment_status_description: payment_authorized means authorized awaiting capture, even when is_paid=false and paid_at=null. Do not request another payment for authorized, processing or received payments. Bulk orders also return campaign_url, recipient count and per-status counts; use the campaign dashboard for individual recipients. Missing carrier evidence is null; processing or a tracking number alone does not prove mailing or delivery. This read does not pay, mail, or acquire receipts.

`postalform.pay_order`Get an MPP challenge or pay an existing MPP PDF, letter, workflow-form order, or bulk letter campaign after buyer approval.

When switching from create_machine_order, omit the credential first to get this payment endpoint’s challenge. Review the preview or campaign_url, recipient count and total. No document or addresses are resubmitted. Without payment_authorization this only returns a challenge; with it, this can pay and send real mail. Reuse the same order_id on retries and follow the returned payment status.	Get an MPP challenge or pay an existing MPP PDF, letter, workflow-form order, or bulk letter campaign after buyer approval.
