Supported Triggers and Actions

Notis builds workflows that link Google Calendar to Yelp. A trigger fires from one place; an action lands in another.

Google Calendar triggers

Yelp actions

Attendee Response Changed

Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.

TriggerPolling

Autocomplete Search

Get autocomplete suggestions for businesses, categories, and search terms on Yelp based on partial text input. Returns matching businesses with their Yelp IDs, relevant category suggestions, and additional search term recommendations. Use this action when users are typing search queries and need real-time suggestions to refine their search before executing a full business search. Location coordinates (latitude/longitude) are optional but can improve suggestion relevance for geographic searches.

ActionInstant

Event Canceled or Deleted

Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.

TriggerPolling

Get Business Details

Get detailed information about a specific business on Yelp using its business ID or alias. Returns comprehensive business information including hours (in the business's local timezone), photos, reviews, and location details. The returned `url` field is the Yelp listing page, not the business's own website. Response fields such as `phone` and `website` may be null; handle missing values explicitly. Avoid many parallel calls — HTTP 429 throttling applies; limit concurrency to ~5 parallel requests with exponential backoff.

ActionInstant

Event Starting Soon

Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.

TriggerPolling

Get Business Reviews

Get reviews for a specific business on Yelp using its business ID or alias. Returns up to 3 review excerpts for the business.

ActionInstant

Calendar Event Changes

**SOON TO BE DEPRECATED** - Use Calendar Event Sync (polling trigger) instead. Real-time webhook trigger for calendar event changes. Returns event metadata only. For full event data, use Calendar Event Sync (polling trigger).

TriggerInstant

Get Category Details

Get detailed information about a specific Yelp category by its alias. Returns category metadata including the human-readable title, parent categories, and country availability lists. Use this action when you need to understand category hierarchies, check category availability by country, or get the proper display name for a category alias. The alias parameter must be a valid Yelp category identifier — use the list categories endpoint to discover available aliases.

ActionInstant

Event Created

Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.

TriggerPolling

Get Event Details

Get detailed information about a specific Yelp event using its event ID. Returns comprehensive event information including dates, location, cost, attendance counts, and associated business details. Use this action when you need to retrieve full details about a specific event that you already have the ID for. Event IDs can be obtained from the search events or featured events endpoints.

ActionInstant

Calendar Event Sync

Polling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook).

TriggerPolling

Get Featured Event

Get the featured event for a given location on Yelp. Featured events are chosen by Yelp's community managers and represent notable happenings in the specified area. Use this action when you need to discover the highlighted or recommended event for a specific city, region, or coordinates. The returned `event_site_url` is the Yelp event page, not the event's own external website. Response fields such as `business_id`, `cost`, and `tickets_url` may be null; handle missing values explicitly.

ActionInstant

Event Updated

Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.

TriggerPolling

Get Review Highlights

Get review highlights for a specific business on Yelp using its business ID or alias. Returns summarized key points and themes from customer reviews. IMPORTANT: This endpoint requires Yelp Places API Premium Plan access. Without Premium Plan, requests will return a 403 NOT_AUTHORIZED error. For basic review access, consider using the Get Business Reviews action instead, which is available on Enhanced and Premium plans. Note: Get Business Reviews returns at most 3 recent reviews per call, while this action synthesizes themes across the full review history.

ActionInstant

List Categories

List all Yelp business categories across all locales by default. Returns category aliases, titles, parent relationships, and geographic availability. Use this action when you need to discover valid category aliases for filtering business searches or when building category-based navigation. The locale parameter allows filtering to categories available in specific regions while translating category names to the local language.

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 recurring schedule, and soon, your own database.

Integration triggers

Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,000+ 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.

Recurring triggers

Cron-style schedules run a workflow on the clock. Daily standups, hourly syncs, business-hours-only digests: the workhorse of Notis.

Database triggers

Watch a row, query, or threshold in your own database and fire the moment the data changes. Row inserted, value crosses a limit, query starts matching.

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.
