Integration
Connect Google Calendar and Greenhouse
When Attendee Response Changed fires in Google Calendar, your agent runs Create Candidate Note in Greenhouse, or Application Updated in Greenhouse to Create Event in Google Calendar. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

Triggers and actions 21 triggers · 83 actions
Trigger
Attendee Response ChangedPolling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Trigger
Calendar Event SyncPolling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook).
Trigger
Event Canceled or DeletedTriggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Trigger
Event CreatedPolling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
Trigger
Event Starting SoonTriggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.
Trigger

Action
Acl DeleteDeletes an access control rule from a Google Calendar. Use when you need to remove sharing permissions for a user, group, or domain.
Action
Acl GetRetrieves a specific access control rule for a calendar. Use when you need to check permissions for a specific user, group, or domain.
Action
Acl InsertCreates an access control rule for a calendar. Use when you need to grant sharing permissions to a user, group, or domain.
Action
Acl ListRetrieves the list of access control rules (ACLs) for a specified calendar, providing the necessary 'rule_id' values required for updating specific ACL rules.
Action
Acl PatchUpdates an existing access control rule for a calendar using patch semantics (partial update). This allows modifying specific fields without affecting other properties. IMPORTANT: The ACL rule must already exist on the calendar. This action cannot create new rules. If you receive a 404 Not Found error, the rule does not exist - use ACL insert to create it first, or use ACL list to verify available rules. Each patch request consumes three quota units. For domain-type ACL rules, if PATCH fails with 500 error, this action will automatically fallback to UPDATE method.
Action
Acl UpdateUpdates an access control rule for the specified calendar.
Action
Acl WatchTool to watch for changes to ACL resources. Use when you need to set up real-time notifications for access control list modifications on a calendar.
Action
Batch EventsExecute up to 1000 event mutations (create/patch/delete) in one Google Calendar HTTP batch request with per-item status/results. Use this to materially reduce round-trips for bulk operations like migrations, cleanup, or large-scale updates.
Action
Calendar List DeleteTool to remove a calendar from the user's calendar list. Use when you need to unsubscribe from or hide a calendar from the user's list.
Action
Calendar List GetRetrieves metadata for a SINGLE specific calendar from the user's calendar list by its calendar ID. This action requires a calendarId parameter and returns details about that one calendar only. NOTE: This does NOT list all calendars. To list all calendars in the user's calendar list, use GOOGLECALENDAR_CALENDAR_LIST_LIST instead.
Action
Calendar List InsertInserts an existing calendar into the user's calendar list.
Action
Calendar List PatchUpdates an existing calendar on the user's calendar list using patch semantics. This method allows partial updates, modifying only the specified fields.
Action
Calendar List UpdateUpdates an existing entry on the user\'s calendar list.
Action
Calendar List WatchWatch for changes to CalendarList resources using push notifications. Use this to receive real-time updates when calendar list entries are modified.
Action
Calendars DeleteDeletes a secondary calendar. use calendars.clear for clearing all events on primary calendars.
Action

Action
Channels StopTool to stop watching resources through a notification channel. Use when you need to discontinue push notifications for a specific channel subscription.

Optional parameters include description, location, and timezone.

Action
Delete EventDeletes a specified event by `event id` from a google calendar (`calendar id`); this action is idempotent and raises a 404 error if the event is not found.
Action
Duplicate CalendarCreates a new, empty google calendar with the specified title (summary).
Action
Events GetRetrieves a SINGLE event by its unique event_id (REQUIRED). This action does NOT list or search events - it fetches ONE specific event when you already know its ID. If you want to list events within a time range, search for events, or filter by criteria like time_min/time_max, use GOOGLECALENDAR_EVENTS_LIST instead.
Action
Events ImportTool to import an event as a private copy to a calendar. Use when you need to add an existing event to a calendar using its iCalUID. Only events with eventType='default' can be imported.
Action
Events InstancesReturns instances of the specified recurring event.
Action
Events ListReturns events on the specified calendar.
Action
Events List All CalendarsReturn a unified event list across all calendars in the user's calendar list for a given time range. Use when you need a single view of all events across multiple calendars. An inverted or incorrect time range silently returns empty results rather than an error. An empty `items` list means no events matched the filters—adjust `time_min`, `time_max`, or `q` before concluding no events exist.
Action
Events MoveMoves an event to another calendar, i.e., changes an event's organizer.
Action
Events WatchWatch for changes to events resources.
Action

Action
Settings ListReturns all user settings for the authenticated user.
Action
Settings WatchWatch for changes to settings resources.
Action

Action
Update Acl RuleUpdates an access control rule for the specified calendar.
Action

Questions
Google Calendar and Greenhouse, answered
What can start an automation from Google Calendar?
Any of Google Calendar's 6 triggers in the catalog, including Attendee Response Changed, Event Created, Event Updated and Calendar Event Sync. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Greenhouse when something happens in Google Calendar?
Any of Greenhouse's 38 actions, including Create Application, Create Candidate, Create Candidate Note and Create Interview. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Greenhouse to Google Calendar?
Yes. When something happens in Greenhouse, your agent can act in Google Calendar too. This page covers both directions: Greenhouse's triggers and Google Calendar's actions are listed here as well.
Do I have to build a connector for Google Calendar or Greenhouse?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Google Calendar and Greenhouse without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
