Count Attendees

One or more Zuddl event IDs to scope the search to. Omit to search across all events the caller is authorized for.

Filter criteria. ALL criteria are combined with AND; for an OR across different fields, call this tool once per condition. To match any of several values of the SAME field, use one criterion with the in operation (e.g. status in [PENDING, APPROVED]). Each criterion applies one operation to one field. Only the field/operation combinations listed below are valid:

• email (operations: eq, in, like, ilike): Attendee email address. Use this when the user provides an email — it identifies a unique attendee.
• firstName (operations: ilike, not_ilike): Attendee first name. Combine with lastName for a precise full-name search; for a single name token whose position is unknown use the virtual name field instead.
• lastName (operations: ilike, not_ilike): Attendee last name. Combine with firstName for a precise full-name search; for a single name token whose position is unknown use the virtual name field instead.
• ticketTypeId (operations: eq, in): Ticket type ID (UUID). Only use when the user asks about a specific ticket type; resolve names to IDs with search_ticket_type first.
• flowId (operations: eq, in): Registration flow ID (UUID). Scopes results to attendees registered through specific registration flows; resolve names to IDs with search_flow first.
• bio (operations: eq, like, ilike): Attendee bio / about text.
• designation (operations: eq, like, ilike): Attendee job title / designation (e.g. 'CTO', 'Product Manager').
• company (operations: eq, like, ilike): Attendee company name. With the ilike operation, matching also checks the email domain, since the company name often appears there (e.g. 'Acme' matches jane@acme.com).
• phoneNumber (operations: eq): Attendee phone number (exact match only).
• country (operations: eq, like, ilike, in): Country the attendee provided at registration.
• ipCity (operations: eq, in, like, ilike): City derived from the attendee's IP address at registration time.
• ipState (operations: eq, in, like, ilike): State/region derived from the attendee's IP address at registration time.
• ipCountry (operations: eq, in, like, ilike): Country derived from the attendee's IP address at registration time.
• status (operations: eq, in): Registration status. Omit to include all statuses. Values: one of PENDING, REJECTED, APPROVED, DELETED, APPROVED_NOT_REGISTERED, INCOMPLETE.
• source (operations: eq, in): How the registration was created (e.g. self sign-up vs. imported). Values: one of LANDING_PAGE_V1, LANDING_PAGE_V2, DUDA_REGISTRATION_FORM, DUDA_TICKETING_BUYER, DUDA_TICKETING_MAPPING, EMBED_REGISTRATION_FORM, TICKETING_BUYER, TICKETING_MAPPING, BULK_IMPORT, ATTENDEE_INVITE, ATTENDEE_ADD_FORM, HUBSPOT, SALESFORCE, MARKETO, EXPLARA, PROTECH, CERTAIN, UNKNOWN, REGISTRATION_WEBHOOK, ANDROID_ORGANIZER_APP, IOS_ORGANIZER_APP, AVENTRI, EVENT_BRITE, PARDOT, EMBED_FLOW, TEAM_OR_PLAN_CHANGE_INTERNAL, SPEAKER_ADD_FORM, BULK_SPEAKER_IMPORT, CREATE_EVENT, MOVE_EVENT, ADD_TO_TEAM, LEAD_SCAN, PARENT_EVENT, EVENT_REGISTRATION_API_V1, ZOOM_IMPORT.
• sourceType (operations: eq, in): Source type of the registration. Values: one of ATTENDEE_SIDE, ORGANIZER_SIDE, INTEGRATION, UNKNOWN, LEAD_CAPTURE, ZUDDL_API.
• createdBy (operations: eq): Account ID of the user who created the registration (exact match).
• createdAt (operations: eq, gt, lt, gte, lte, between): When the registration was created. ISO-8601 with offset, e.g. 2026-05-01T00:00:00Z. Use gte/lte for open ranges or between for a closed range. Values: ISO-8601 date-time with offset, e.g. 2026-05-01T00:00:00Z.
• name (operations: ilike): Attendee name matched against first name OR last name. Accepts a full name: it is split on whitespace and every part must match the first or last name, in any order. Use when it's unclear how the name splits into first and last name. If multiple attendees match, ask the user to clarify by email.
