The waivers collected for one event: who signed, when, and the participants. Personal data of signers. GET /GetWaiversForEvent.

waiverfile_search_waiversread-only

Search signed waivers by free-text terms (a signer's name, email or phone). Personal data of signers. GET /SearchWaivers.

waiverfile_get_waiverread-only

One signed waiver by id: signer, date signed, participants, collected form data, event and the agreement text. Set lite for only the collected form data (no agreement text or event info). Signature and image bytes are never returned. GET /GetWaiver or /GetWaiverLite.

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 /GetAllWaiversByDateRangeLite.

waiverfile_export_waiver_dataread-only

A page of flat waiver rows for a date range (the data behind the WaiverFile export): standard fields, optionally every custom form field as a column, and participants either as one comma-separated column or one row each. Personal data of signers. GET /GetWaiverData.

waiverfile_count_waiversread-only

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 waiverfile_list_waivers). pages_at_page_size is waiver_count divided by page_size (default 25), rounded up.

waiverfile_create_event

Create a waiver event (a class, tour or session that collects waivers) with a name and a start/end time (UTC). Optionally an all-day flag, category, location, signing cut-off, participant limit and which waiver forms to attach (default: WaiverFile's own choice, see list_waiver_forms). Not idempotent: calling twice creates two events. Sends no email. POST /InsertEvent.

waiverfile_update_eventcan modify

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 send its current values for the fields you do not change. Same input twice gives the same result. POST /UpdateEvent.

waiverfile_invite_event_managerscan modify

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_exists suppresses the email for people who already have an account). Cannot be undone by this server except with the vendor's

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.
