Trigger Types
Four ways to start an automation.
A trigger is the event that kicks a workflow off. Notis supports four kinds: an event in a connected app, an inbound webhook, a schedule (recurring or one-time), and a change in one of your Notis databases.
Integration triggers
Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,500+ apps can start a workflow.
New Notion pageStripe chargeCalendar event
Webhook triggers
A unique URL per workflow. Anything that can send an HTTP POST can start an automation, including no-code tools that speak webhooks.

Scheduled triggers
Run a workflow on the clock, on a recurring schedule or once at a set date and time. Daily standups, hourly syncs, a one-off launch reminder: the workhorse of Notis.

Database triggers
Fire when a row in one of your Notis databases is added or edited, with optional filters on its properties. New lead added, status changed, value crosses a limit.

Why AI automation
Classic automation breaks. AI adapts.
Same triggers and actions, smarter middle. AI handles the fuzziness that breaks traditional Zapier-style workflows the moment a field gets renamed.
