Create Event Attendees signal

Turn a LinkedIn event's attendee list into leads. Point the signal at one or more LinkedIn event URLs and every person attending — filtered to your target personas and ICP — is delivered to your webhookUrl as an enriched lead. Event attendees are high-intent: they self-selected into a topic, so you reach an audience that already raised its hand.

Input: signal name, webhookUrl, and a config object with the LinkedIn event URLs to track (eventUrls, required — each must contain the event's numeric id, e.g. .../events/<slug>7318198749535633408/), plus your ICP filters: targetPersonas and customPersonaTitles (which attendees qualify, matched on their headline), excludedTitles, companySizeFilters / excludedCompanySizeFilters, locations / excludedLocations, industryFilters / excludedIndustryFilters. Industry values must be the exact names returned by GET /api/v1/signals/industries — a single industry ("Software Development") or a category ("Technology and Media"); matching is exact, so a near-miss matches nothing. An attendee whose company industry cannot be determined is kept, not dropped, when you filter by industry (their company.industry is then ""); an industry exclusion likewise only removes attendees whose industry is known. Optional getEmails adds email enrichment. Top-level dailyLeadLimit (1–999,999, default 100), status (draft | active | paused, default draft), and duplicateHandling (refuse | allow | Xd, default allow) complete the request.

Output: 201 Created returns the signal object (id, name, status, signalTypeId, webhookUrl, config, dailyLeadLimit, leadsToday, leadsTotal, duplicateHandling, createdAt, updatedAt, lastLeadAt). Each matching attendee is then POSTed to your webhookUrl as a JSON lead (WebhookEventAttendeesPayload) with three blocks. signal: id, name, type (event_attendees), last_signal ("Event Attendees"), last_signal_date (YYYY-MM-DD), and tracked_company — the LinkedIn event URL the attendee was found at. contact: lead_id, created_at, first_name, last_name, email (when getEmails is enabled), phone, title, location, linkedin_profile_url, sales_navigator_profile_url, matched_persona. company: name, website, linkedin_url, description, industry, location, employee_count, employee_range, tech_stack, homepage_title, meta_description — the company fields populate when you filter by company size or industry. Every documented key is always present; unavailable values are the empty string "" (never null). Attendees outside your persona or ICP filters are dropped and never sent.

Use cases:

• Warm-intent outreach — attendees self-selected into your topic; open with the exact event they showed up to.
• Conference & webinar follow-up — reach everyone who attended a relevant industry event, not just the few you met.
• Competitive events — capture the audience of a competitor's or partner's webinar and pitch your alternative.
• Persona-filtered guest lists — keep only the decision-makers (e.g. CMOs, Heads of Growth) among the attendees.
