Integration
Connect Mailchimp and Google Calendar
When Campaign Sent (instant) fires in Mailchimp, your agent runs Create Event in Google Calendar, or Attendee Response Changed in Google Calendar to Add Order Line Item in Mailchimp. 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.
Build solutions, not workarounds.

Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.
Setup guide (opens in a new tab)Any other MCP client
Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.
Setup guide (opens in a new tab)Google Calendar holds the meetings, webinars and campaign dates your team runs; Mailchimp holds the people you email about them. Connecting the two means an RSVP in Google Calendar can update a member, tag or note in Mailchimp, and a campaign sending or a new audience in Mailchimp can put the follow-up work on a calendar.

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.

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
Calendars UpdateUpdates metadata for a calendar.
Action
Channels StopTool to stop watching resources through a notification channel. Use when you need to discontinue push notifications for a specific channel subscription.
Action
Create CalendarCreates a new secondary Google Calendar with the specified title and optional settings. Use this action when you need to create a new calendar for organizing events separately from the primary calendar. The authenticated user becomes the owner of the newly created calendar. Optional parameters include description, location, and timezone.
Action
Create EventCreates 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.
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
Find EventFinds events in a specified google calendar using text query, time ranges (event start/end, last modification), and event types; ensure `timemin` is not chronologically after `timemax` if both are provided.
Action
Find Free SlotsFinds free/busy time slots in google calendars for specified calendars within a defined time range (defaults to the current day utc if `time min`/`time max` are omitted), enhancing busy intervals with event details; `time min` must precede `time max` if both are provided.
Action
Free Busy QueryReturns free/busy information for a set of calendars.
Action
Get CalendarRetrieves a specific google calendar, identified by `calendar id`, to which the authenticated user has access.
Action
Get Current Date TimeGets the current date and time, allowing for a specific timezone offset.
Action
List Acl RulesRetrieves the list of access control rules (acls) for a specified calendar, providing the necessary 'rule id' values required for updating specific acl rules.
Action
List CalendarsRetrieves calendars from the user's google calendar list, with options for pagination and filtering.
Action
Patch CalendarPartially updates (patches) an existing google calendar, modifying only the fields provided; `summary` is mandatory and cannot be an empty string, and an empty string for `description` or `location` clears them.
Action
Patch EventUpdates specified fields of an existing event in a google calendar using patch semantics (array fields like `attendees` are fully replaced if provided); ensure the `calendar id` and `event id` are valid and the user has write access to the calendar.
Action
Quick AddParses 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'.
Action
Remove AttendeeRemoves an attendee from a specified event in a google calendar; the calendar and event must exist.
Action
Settings GetTool to return a single user setting for the authenticated user. Use when you need to retrieve a specific calendar setting value.
Action
Settings ListReturns all user settings for the authenticated user.
Action
Settings WatchWatch for changes to settings resources.
Action
Sync EventsSynchronizes google calendar events, performing a full sync if no `sync token` is provided or if a 410 gone error (due to an expired token) necessitates it, otherwise performs an incremental sync for events changed since the `sync token` was issued.
Action
Update Acl RuleUpdates an access control rule for the specified calendar.
Action
Update EventUpdates an existing event by `event id` in a google calendar; this is a full put replacement, so provide all desired fields as unspecified ones may be cleared or reset.
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.

Questions
Mailchimp and Google Calendar, answered
Can an RSVP in Google Calendar update someone in Mailchimp?
Yes. The Attendee Response Changed trigger reports the attendee and their current status, so you can branch on accepted replies and then use Add or update member, Add tag to member or Add Member Note in Mailchimp for that person.
What can a Mailchimp campaign send do in Google Calendar?
The Campaign Sent trigger fires when a campaign finishes sending, and it can create an event in Google Calendar, for example a slot to read the report. You can also use Quick Add or Find Event if you prefer plain text or want to check an existing booking first.
What can start an automation from Mailchimp?
Any of Mailchimp's 5 triggers in the catalog, including Campaign Sent (instant), New list, Member Email Changed (instant) and Member Profile Updated (instant). Describe the moment in plain language and your agent picks the right one.
What can your agent do in Google Calendar when something happens in Mailchimp?
Any of Google Calendar's 45 actions, including Create Event, Duplicate Calendar, Find Event and Create Calendar. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Google Calendar to Mailchimp?
Yes. When something happens in Google Calendar, your agent can act in Mailchimp too. This page covers both directions: Google Calendar's triggers and Mailchimp's actions are listed here as well.
Do I have to build a connector for Mailchimp or Google Calendar?
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 Mailchimp and Google Calendar 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.
