Ask your agent in plain language. Each of these maps to a real tool on the server.
manage_collection
Create, update, or delete a collection in your Customer.io workspace. Collections store reusable data (promotions, events, courses, etc.) that you can reference in campaigns with Liquid. You can provide data as JSON or point to a URL for CSV/JSON data.
list_collections
Retrieve all collections in your Customer.io workspace. Collections are sets of reusable data (promotions, events, courses, etc.) that you reference in campaigns with Liquid templates.
manage_manual_segment
Add or remove people from a manual segment. Manual segments are static groups that you manage explicitly, unlike data-driven segments that update automatically based on criteria.
track_event
Track a custom event for a person or an anonymous event. Events represent actions people perform — button clicks, purchases, page views, etc. You can use events to trigger campaigns and segment users. Supports tracking events attributed to a specific person, anonymous events (associated later), and page/screen views.
list_segments
Retrieve all segments in your Customer.io workspace. Segments are named groups of people who share characteristics or behaviors. Returns both data-driven and manual segments.
list_campaigns
Retrieve campaigns from your Customer.io workspace. Returns information about campaigns including their names, states, types, and tags.
manage_device
Register or remove a device for push notifications associated with a person. Use this to add mobile devices (iOS/Android) to a person for push notification targeting, or to remove a device when a user logs out or opts out.
search_people
Search for people in your Customer.io workspace using complex filters. Find people by segment membership, attribute values, or other criteria. Returns up to 1000 people per request.
get_person
Look up a person in your Customer.io workspace and retrieve their attributes, segments, and recent activity. You can look up a person by their ID, email, or cio_id.
send_transactional_message
Send a transactional message (email, push notification, or SMS) to a person. Transactional messages are for receipts, password resets, order confirmations, and other messages your audience implicitly expects to receive. You can reference a pre-built template by its transactional message ID, or provide the full message content inline.
delete_person
Delete a person from your Customer.io workspace. This removes the person and their data, but does not suppress them — they can be re-added later. Use the suppress action if you want to prevent the person from being re-added.
merge_people
Merge two person profiles into one. The secondary person's data is consolidated into the primary person's profile, and the secondary profile is removed. Use this to consolidate duplicate profiles.
get_campaign
Retrieve detailed information about a specific campaign, including its actions, metrics, and configuration. Optionally fetch campaign metrics with configurable time periods.
suppress_person
Suppress or unsuppress a person in your Customer.io workspace. Suppressing a person removes them and prevents them from being re-added. Unsuppressing allows a previously suppressed person to be added back.
trigger_broadcast
Trigger an API-triggered broadcast to send messages to a wide audience. You set up the broadcast in the Customer.io UI and then trigger it via this action. Broadcasts are ideal for announcements, product launches, event notifications, etc. You can target a segment, a list of customer IDs, or a list of email addresses.
upsert_person
Create a new person or update an existing person in your Customer.io workspace. If no person exists with the given identifier, a new person is created. If a person already exists, their attributes are updated. You can set any custom attributes on the person, including email, name, plan, and any other key-value pairs.
get_segment_membership
Retrieve the people who belong to a specific segment. Returns a paginated list of customer IDs in the segment.
