Describe the whole flow and it is built, tested on every scenario and kept running. Google Calendar **6** triggers Google Calendar **45** actions Relatel **4** triggers Relatel **19** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want Google Calendar and Relatel to do together? Give your AI client this address. `https://mcp.apiant.ai` One 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. ### Set it up in your client ### Claude Code Run this in the directory you want to work in. `claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens. [Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code) ### Claude, web and desktop Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Cursor Add the address to your MCP configuration as a server URL.

Describe the flow you need, at any depth, and your agent builds it and tests every scenario before it ships. Everything your agent can do with Google Calendar and Relatel ## Triggers and actions 10 triggers · 64 actions - Trigger **Attendee Response Changed** Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status. - Trigger **Calendar Event Sync** Polling trigger that returns full event data including details, attendees, and metadata.

Returns minimal data: event_id, summary (if available), and cancellation timestamp. - Trigger **Event Created** Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info. - Trigger **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. - Trigger **Event Updated** Triggers when an existing Google Calendar event is modified.

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 Update** Updates an access control rule for the specified calendar. - Action **Acl Watch** Tool 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 Events** Execute up to 1000 event mutations (create/patch/delete) in one Google Calendar HTTP batch request with per-item status/results.

Any of Relatel's 19 actions, including Send SMS, Update contact, Add comment and Add contact. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Relatel to Google Calendar? Yes.

This page covers both directions: Relatel's triggers and Google Calendar's actions are listed here as well. ### ### Do I have to build a connector for Google Calendar or Relatel? 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 Relatel 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.
