Swytchcode is a CLI execution layer that sits between your AI agent and production APIs like Customer.io—handling authentication, retries, idempotency, and policy control so your agent can call real APIs safely instead of failing silently.

How do I get started with Swytchcode?

Run "npx swytchcode" to install the CLI. Your first 2 live commands don't need an account; after that, run "swytchcode login". Dry runs, --explain, and demos don't count. Then run "swytchcode get customer_io" to pull the Customer.io manifest and you're ready to call it from your agent.

How does an AI agent actually call the Customer.io API through Swytchcode?

Your agent runs "swytchcode exec customer_io. " with arguments. Swytchcode validates the call against the Customer.io manifest schema, attaches your stored credentials, executes the request, and returns structured JSON your agent can act on—no auth or HTTP handling lives in your agent's code.

What happens if a Customer.io call fails, times out, or hits a rate limit?

Swytchcode assigns every Customer.io call an idempotency key and retries it automatically on transient failures or rate limits. If your agent re-runs the same action, Swytchcode recognizes the retry and prevents duplicate writes—a raw HTTP call wouldn't give you that safety net.

Can I restrict which Customer.io actions my agent is allowed to run?

Yes. Allow and deny rules, available on every plan, can limit which Customer.io actions run. Approval workflows, available on Business and above, hold a matching command until someone approves or denies it in that workspace's Slack or Telegram channel. If nobody responds within 48 hours, the command doesn't run.

Where does Swytchcode store my Customer.io credentials?

You authenticate once, and Swytchcode stores and refreshes your Customer.io credentials server-side. Your agent—and the LLM behind it—only ever sees action names and results, never raw API keys or tokens.

Do I need to write a custom Customer.io SDK integration for my agent?

No. "swytchcode get customer_io" pulls a pre-built, versioned manifest describing every available Customer.io action and its parameters, so your agent calls actions by name instead of you writing and maintaining request/response glue code.

How is calling Customer.io through Swytchcode different from calling its API directly?

A direct call means you handle token refresh, retries, error parsing, and schema drift yourself, with no guardrails on what the agent can execute. Swytchcode does all of that and checks each call against your policy rules first, so an agent can't do something with Customer.io you didn't explicitly approve.

Do I need a specific framework to call Customer.io?

No. Swytchcode runs as a CLI or MCP server, so any agent, IDE assistant, or script can call it. Use the LLM and framework your team prefers.

Does Swytchcode log what my agent does with Customer.io?

Yes. Every Customer.io call—action, arguments, result, and timestamp—is written to a full audit trail, so you can debug unexpected agent behavior or review exactly what ran in production.

Get started

API Integration

Customer.io API for AI Agents

Connect the Customer.io API to your AI agent through Swytchcode. Call the Customer.io API from the agent stack you already run. Swytchcode supplies the manifest, then handles authentication, retries, idempotency, and validation on every call.

Setup guide

How to connect the Customer.io API to an AI agent

Four steps, no SDK, no boilerplate. Every Customer.io call routed through Swytchcode is idempotency-keyed and safe to retry.

1
Install the CLI
Run "npx swytchcode" to install the Swytchcode CLI—no account required to start.
2
Pull the manifest
Run "swytchcode get customer_io" to pull the Customer.io API manifest, including its schema and available actions.
3
Authenticate once
Provide your Customer.io API credentials a single time. Swytchcode stores and refreshes them so your agent never handles raw secrets.
4
Call it from your agent
Run "swytchcode exec customer_io.<action> --key value" from any agent or script. No SDK, no framework lock-in.

swytchcode get customer_io
swytchcode exec customer_io.<action> --key value
