Capabilities

Tools 9

lastfolk_cancel_delivery

Cancel a delivery that the courier has not collected yet (status pending or pickup). Cancelling a delivery that is already cancelled succeeds with changed: false. After pickup, the API refuses with delivery_not_cancellable. Cancelling moves no money in the same call. POST /v1/deliveries/{delivery_id}/cancel.

Discovered
lastfolk_check_environment

Check that the API key environment matches the connected courier provider account, before any delivery is created. Returns match: true when they agree. A mismatch is an error. GET /v1/environment.

Discovered
lastfolk_create_delivery

DISPATCHES a real courier job against a quote_id from lastfolk_create_quote, and starts the billing for it. The quote must be unused and not expired. Use a unique idempotency_key per delivery (an order id works): a retry with the same key and body returns the original delivery and never dispatches a second courier. The same key with a different body is refused. dropoff.phone must be a real, reachable number. POST /v1/deliveries.

Discovered
lastfolk_create_quote

Price a pickup-to-dropoff delivery and get a quote_id. Reserves nothing and charges nothing. The quote is single-use and expires at expires_at; pass quote_id to lastfolk_create_delivery before then. Price amounts are decimal strings: never parse them as floats. POST /v1/quotes.

Discovered
lastfolk_get_billing_profile

Read the account's fiscal identity: legal company name, tax ID and type, and billing address. Exactly seven fields, each text or null. GET /v1/billing-profile.

Discovered
lastfolk_get_delivery

Read one delivery: status, tracking URL, ETAs, timestamps, and the dropoff verification_pin the recipient gives the courier. The PIN is a secret: share it only with the recipient. GET /v1/deliveries/{delivery_id}.

Discovered
lastfolk_list_deliveries

List your deliveries, newest first, with status, tracking URL and ETAs. Filter by status, your external_order_id, or a created date range. Page with next_cursor. The dropoff PIN is not in lists: use lastfolk_get_delivery. GET /v1/deliveries.

Discovered
lastfolk_update_billing_profile

Change the account's fiscal identity. Fields you omit or send empty keep their stored value. Send null to clear one field. The tax ID is checked against the resulting billing country, and the whole update is refused if it fails. Changes flow to billing records and invoices. PUT /v1/billing-profile.

Discovered
lastfolk_whoami

Show which LastFolk tenant and environment (sandbox or production) this API key belongs to, plus the key prefix and last four characters. Use it to confirm the key works. GET /v1/whoami.
