Any Tool Can Schedule—Just Webhook Notis
Your AI agent, chatbot, or custom backend sends Notis a simple request. Notis parses it and quick-adds a calendar event instantly.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Quick Add Event
Parses natural language text to quickly create a basic google calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar id` must be valid if not 'primary'.
Why this helps
Founders want their AI agents and custom tools to schedule calendar events but can't integrate them directly, so events are scheduled manually.
- Any tool can schedule events through a simple webhook
- Uses natural language parsing instead of field mapping
- Enables AI agents and bots to manage your calendar
- Reduces manual event creation from external sources
Setup
Build it in a few focused steps.
- 1Connect Google Calendar to Notis.
- 2Ask Notis: 'When you receive a webhook from my AI agent with the text "Schedule meeting with [name] at [time]", quick-add it as a calendar event.'
- 3Notis provides you with a webhook URL to send requests to.
- 4Configure your external tool to send webhooks to that URL.
- 5Test by sending a sample webhook and confirming the event appears.
Questions about this workflow
What format should the webhook payload be in?
JSON is standard. You can send simple text like 'Schedule lunch with Sarah at noon' and Notis will parse it.
Can my AI agent send complex details like attendees?
Yes. Include attendee emails, descriptions, or other details in the webhook payload and Notis will populate the event.
Is the webhook secure?
Yes. Notis provides a secure webhook URL that's unique to your automation, and only accepts requests you configure.
