Custom Webhook-Triggered Calendar Blocks

Important moments deserve protected time. Let your tools trigger it automatically.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Create Event

Creates an event on a google calendar, needing rfc3339 utc start/end times (end after start) and write access to the calendar. by default, adds the organizer as an attendee unless exclude organizer is set to true.

Why this helps

Important business events (support escalations, high-value leads, feature requests from key customers) happen outside Stripe and calendar. Adding calendar blocks manually means they get missed or deferred indefinitely.

  • React to business-critical events instantly
  • Keep your calendar aligned with actual priorities
  • Eliminate admin overhead for manual blocking
  • Respond to opportunities without delays

Setup

Build it in a few focused steps.

  • 1Connect Google Calendar to Notis.
  • 2Create an automation: 'When you receive a webhook from my CRM (or other tool) for high-priority events, block 1 hour on my calendar to address it immediately.'
  • 3Notis will provide you a unique webhook URL to configure in your CRM or custom tool.
  • 4Configure your external tool to send the webhook when priority events occur, then test with a real event.

Questions about this workflow

What information can I send in the webhook?

You can include customer name, issue priority, deadline, and other details. Notis parses the payload and adds relevant context to the calendar block description.

Can different webhooks trigger different calendar blocks?

Yes. Set up multiple automations: one for sales leads (book a 1-hour call), one for support escalations (book 30-min urgent review), etc.

How do I get the webhook URL into my tool?

Notis provides the webhook URL directly. You paste it into your CRM/tool's integration settings, similar to Zapier or Slack.
