Get the SignUpGenius profile of the authenticated user (name, email, member ID, subscription level). Useful as a first call to confirm credentials. Key mode hits /v2/k/user/profile; session mode hits /v3/member/profile.

List groups created by the authenticated user. Returns groupid, title, and member count for each group.

List members of a SignUpGenius group (basic info: name, email, memberid).

Get detailed info for a group member (address, phone, email) when the member has provided it via a sign-up.

Add a member to a SignUpGenius group by email address. First/last name are optional. Writes data — confirm with the user before invoking.

List sign-ups created by the authenticated user. In session mode this returns the full list (active + expired) — filter on enddate client-side if you need only active.

Alias of signupgenius_list_created_active in session mode (v3 returns active + expired together). Filter on enddate client-side.

List ALL sign-ups created by the authenticated user (active and expired).

List sign-ups the user has been invited to.

List sign-ups the user has personally signed up for.

Session mode only. Returns the same sign-up listing the SignUpGenius wizard sees (via /SUGboxAPI.cfm?go=t.getMySignups). Use when you want fuller data than signupgenius_list_created_* provides.

Full report for a sign-up: every slot plus the participant who claimed it (with custom-question answers when present). Requires SIGNUPGENIUS_USER_KEY (Pro subscription) — session mode is not supported for reports.

Report for a sign-up restricted to slots that have already been filled. Requires SIGNUPGENIUS_USER_KEY (Pro subscription) — session mode is not supported for reports.

Report for a sign-up restricted to slots that are still open/empty. Requires SIGNUPGENIUS_USER_KEY (Pro subscription) — session mode is not supported for reports.

List the SLOTS (dates, times, locations, and how many spots are taken/remaining) for any public SignUpGenius sign-up, given its URL, slug, or numeric id. Requires NO auth and works for sheets the user did not create — use this instead of signupgenius_report_* whenever you need slot availability. Participant names appear only when the endpoint publishes them; each item reports the slot's hidenames display setting so an empty list can be explained without implying missing access.

Look up a SignUpGenius sign-up by its public URL or slug (e.g. https://www.signupgenius.com/go/<urlid>-<signupid>-<vanity>). Fetches the rendered page and returns a structured envelope: title, organization, date, time, location, description, creator, and RSVP response counts (when present). Requires no SignUpGenius auth — works even when the server has no API credentials configured. Use this when the user pastes a sign-up link and asks what it is or when it is.

RSVP to a SignUpGenius sign-up (the Yes/No/Maybe-style sheets, including invitations from family/friends). Walks the PreProcessSignup → getSignupInfo → processSignUpFormHandler flow under the hood. Writes data — confirm with the user before invoking. Slot-based sign-ups (e.g. "claim the 3pm slot") are NOT supported by this tool; a slot signup tool is a separate concern.
