Explore Triggers and Actions

Cio auth status

Show the active authentication state. Reports the authenticated user and account, the workspaces the current OAuth token is allowed to access, and whether an agent service-account JWT can be minted. Use this to diagnose auth errors.

ActionTry it

Cio delete api

Delete a resource via the Customer.io API (DELETE only). Always run with dry_run first to preview. Use cio_schema to find the correct path.

ActionTry it

Cio prime

Print LLM-ready instructions for using the Customer.io API. ALWAYS call this first in a new task — it contains the authoritative, version-specific rules for how to drive the API via the other cio_* tools.

ActionTry it

Cio read api

Read from the Customer.io API (GET only). Use cio_schema first to find the correct path and placeholders. Workspace routing is enforced server-side via the caller's OAuth token.

ActionTry it

Cio schema

Introspect the Customer.io API schema. Use this to discover endpoints before calling cio_read_api / cio_write_api / cio_delete_api — never guess paths or field names. Pass no query to list resources; pass a resource name ('campaigns') to list its endpoints; pass 'resource.method' ('campaigns.list'), 'METHOD /path', or '/path' for endpoint detail.

ActionTry it

Cio skills list

List available agent skills — task-specific instruction manuals maintained by Customer.io (routing rules, required params, multi-step workflows).

ActionTry it

Cio skills read

Read the full content of a specific agent skill. Paths look like 'campaigns' for the main skill or 'campaigns/examples.md' for a sub-file — see cio_skills_list for available paths.

ActionTry it

Cio write api

Write to the Customer.io API (POST, PUT, or PATCH). Always run with dry_run first to preview. Use cio_schema to find the correct path, method, and body shape.
