• Zapier: create a Zap with the trigger Webhooks by Zapier → Catch Hook, and copy the URL it gives you. (Webhooks by Zapier needs a paid Zapier plan.)
• Make: start a scenario with Webhooks → Custom webhook, add a webhook, and copy its address.
• n8n, Home Assistant or your own server: any address that starts with https:// and accepts a JSON POST works.

What VisitorLog sends

{
  "event": "sign_in",
  "visitor": "Ana Ruiz",
  "host": "Tom Sawyer",
  "fields": [
    { "label": "Company", "value": "Acme" },
    { "label": "Reason for visit", "value": "Interview" }
  ],
  "timestamp": "2026-10-02T14:05:00Z",
  "text": "Ana Ruiz has arrived to see Tom Sawyer · 2:05 PM\nCompany: Acme\nReason for visit: Interview"
}

event is sign_in or sign_out. host is only included when the visitor picked someone from your Employee List. text is a ready-made message you can forward as-is.

For the whole office

1. On the iPad, open VisitorLog Settings (enter your admin password if you set one).
2. Tap Host notifications and paste the URL into Webhook URL.
3. Check that Service shows the app you expected (Slack, Microsoft Teams…).
4. Tap Send Test Message. A test message should appear in your channel within a few seconds.
5. Choose whether to be notified on sign-in, sign-out, or both.

For one person

Want alerts to go straight to a particular employee (for example their own Slack channel or a private chat space)?

1. In Settings, open Employee List and tap the employee.
2. Paste their webhook URL under Personal notifications and tap Save.
3. Make sure the “Who are you visiting?” field on your sign-in form has Show Employee List switched on.

When a visitor picks that employee, the alert goes to their webhook. Everyone else's visitors still go to the office webhook.
