What it can do

Tool names and descriptions exactly as the server reported them on Nov 14, 2026. The maker wrote them, not us; we show them as plain text.

• waiverfile_find_waivers_by_reference

  Find waivers by the reference ids an outside booking or reservation system attached to them (referenceID1, 2, 3). Give at least one of reference_id_1/2/3, or reference_id_any to match all three fields. GET /GetWaiversByReferenceID.

• waiverfile_list_waivers

  A page of the waivers signed in a date range. Set lite for only the collected form data (smaller). For a flat export with custom form columns use waiverfile_export_waiver_data; for totals use waiverfile_count_waivers. Personal data of signers. GET /GetAllWaiversByDateRange or /Ge

• waiverfile_export_waiver_data

• waiverfile_count_waivers

  How many waivers a date range holds: record_count (GetWaiverDataCount, the rows waiverfile_export_waiver_data pages through) and waiver_count (GetAllWaiversByDateRangePageCount, which WaiverFile documents as the number of waivers in the range, used to work out the pages of waiver

• waiverfile_update_event

  Update an existing event. WaiverFile replaces the whole event, so name, start, end and all_day are required and anything left out is reset: category_id empty = no category, waiver_form_ids empty = ALL active forms are attached. Read the event first (waiverfile_list_events) and se

• waiverfile_invite_event_managers

  SENDS EMAIL: invites people (by email address) to manage one event; they can log in to WaiverFile and see its signers and participants, with the fields set in the account settings. WaiverFile emails each address, with your optional message in the body (skip_email_if_account_exist

• waiverfile_create_event_category

  Create an event category (a label to group events). Not idempotent: calling twice with the same name creates two categories. POST /InsertEventCategory.
