Check team availability automatically via webhook

When your scheduling system sends a webhook asking 'what's the team's availability next Tuesday?', Notis instantly checks everyone's calendar and returns free slots.

Query Free/Busy Information

Returns free/busy information for a set of calendars.

Why this helps

Neurodivergent team leads struggle with the overhead of manual availability checking across multiple people. Asking 'are you free?' and waiting for responses kills momentum. Automating this is transformative.

  • Instant team availability without asking each person individually
  • External systems get availability data automatically
  • Reduce the coordination overhead of scheduling team meetings

Setup

Build it in a few focused steps.

  • 1Connect Google Calendar (team members' calendars).
  • 2Tell Notis: 'When you receive a webhook requesting team availability, check everyone's calendars and return free slots.'
  • 3Notis generates a webhook URL for your scheduling system to call.
  • 4Configure your external system to send requests to that webhook.
  • 5Test by triggering a request from your external system.

Questions about this workflow

How do I add team members to the availability check?

Tell Notis which team members' calendars to check, and provide their email addresses or calendar links.

Can Notis find overlapping free time across multiple people?

Yes. That's the default—Notis finds time when everyone is free, not just when each person individually is free.

What format does Notis return availability in?

Notis sends back a structured response with available time slots. You can customize the format based on your system's needs.
