# Connect Calendly to Customer.io

When **New scheduled event (polling)** fires in [Calendly](https://apiant.ai/connections/calendly), your agent runs **Create Event** in [Customer.io](https://apiant.ai/connections/customer-io). Describe the whole flow and it is built, tested on every scenario and kept running.

Calendly **2** triggers Calendly **18** actions Customer.io **10** actions

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want Calendly and Customer.io 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. Cursor signs you in in your browser.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Zed

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

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)](https://apiant.ai/docs/mcp)

### 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.

**Update event type availability schedule**

Replaces a single host's availability schedule on a Calendly event type with explicit date rules (full overwrite). Built for CalendarConnect: push real Mindbody bookable slots into Calendly so only MBO-bookable times are offered. CRITICAL: the host is targeted by the NESTED availability_rule.user — a top-level user alone is silently ignored and Calendly replaces the OAuth token owner's schedule instead. Always verify stored_user equals the requested host before trusting the result. For round-robin events, call once per host.

Questions

## Calendly and Customer.io, answered

###

### What can start an automation from Calendly?

Any of Calendly's 2 triggers in the catalog, including New scheduled event (polling) and Canceled scheduled event (polling). Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Customer.io when something happens in Calendly?

Any of Customer.io's 10 actions, including Create Anonymous Event, Create Event, Send API-triggered broadcast and Send transactional email. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from Customer.io to Calendly?

Customer.io has no triggers in the catalog today, so automations start in Calendly. If you need the other direction, ask: your agent reads Customer.io's API documentation and adds it.

###

### Do I have to build a connector for Calendly or Customer.io?

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 Calendly and Customer.io 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.
