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

## What do you want Zoho Billing 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.

## Zoho Billing and Customer.io, answered

###

### What can start an automation from Zoho Billing?

###

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

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 Zoho Billing?

Customer.io has no triggers in the catalog today, so automations start in Zoho Billing. 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 Zoho Billing 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 Zoho Billing 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.

###
