• checkfront_add_to_booking_session ~377 tokens
  Start or modify a booking session: add one or more SLIPs (from a rated checkfront_get_item / checkfront_list_items call), replace a line with a new SLIP (line_id + slip), or alter lines (quantity, 'remove', 'optin'/'optout' for package add-ons). Holds the inventory while the session is open; NOTHING
• checkfront_check_in_booking ~186 tokens

• checkfront_create_booking ~328 tokens

Creates a real reservation that consumes inventory and may n
• checkfront_end_booking_session ~174 tokens
  Abandon a booking session: 'clear' empties its items, 'end' closes it. Releases the inventory it was holding; no booking is affected. Checkfront: POST /api/3.0/booking/session/clear or /booking/session/end.
• checkfront_get_availability_calendar ~293 tokens

• checkfront_get_booking_form ~126 tokens
  Fetch the customer-details form for a booking (booking_form_ui): every field id (customer_name, customer_email, …), its label, type and whether it is required. Call this before checkfront_create_booking to know which `form` fields to send. Checkfront: GET /api/3.0/booking/form.
• checkfront_get_booking_session ~140 tokens

• checkfront_get_company ~108 tokens
  Fetch the connected Checkfront account's company configuration — name, URL, plan, currency, timezone, locale and date/time formats. A cheap way to confirm the host and credentials work. Checkfront: GET /api/3.0/company.

  List bookings, newest filters first — by status, customer, dates, item or partner. Each row has the booking code, status, totals (total, tax_total, paid_total), customer name/email, summary and date_desc. Paged (default 100/page); the response's request.pages tells you how many pages exist. Checkfro

• checkfront_list_events ~117 tokens

• checkfront_list_items ~619 tokens
  List the enabled inventory items (tours, activities, rentals, rooms). With NO dates this is the plain catalogue. Pass start_date (and end_date / param quantities) to get a RATED response: per-item availability, pricing and a SLIP token — the SLIP is what checkfront_add_to_booking_session needs to bo
