How do I authenticate with Customer.io using this skill?

Authentication is handled via the Composio MCP server at rube.app/mcp. If no active connection exists, Claude will provide an authentication link to connect your account.

Can I send broadcasts to multiple segments at once?

Yes, while the tool requires one audience parameter, you can use the 'recipients' object which supports complex filters with 'and', 'or', and 'not' operators.

What format should I use for time-based metrics?

When fetching message metrics using CUSTOMERIO_GET_MESSAGES, you must use Unix timestamps for the start_ts and end_ts parameters.

Are there rate limits for triggering broadcasts?

Yes, Customer.io enforces a rate limit of 1 request per 10 seconds per specific broadcast ID when triggering through this API.
