## Tools

### Add Person to Group

**Slug:** `CUSTOMERIO_ADD_PERSON_TO_GROUP`

Tool to add people to a group in Customer.io. Groups represent objects like companies, accounts, or projects that people belong to. Use when you need to establish relationships between people and organizational entities.

### Create Profile Alias

**Slug:** `CUSTOMERIO_CREATE_ALIAS`

Tool to create an alias to merge multiple profiles in Customer.io. Use when you need to support multiple identifiers for a single person. The alias operation moves all data from the previous_id profile to the user_id profile, consolidating them into a single canonical profile.

### Suppress Customer Profile

**Slug:** `CUSTOMERIO_CUSTOMER_IO_SUPPRESS_PERSON`

Suppress a customer profile to permanently delete it and prevent re-adding with the same identifier. IMPORTANT: This action requires Track API credentials (Basic Auth with siteId:apiKey), not App API credentials. Suppression also deletes the customer profile - you don't need to call a separate delete endpoint. Use this for GDPR/CCPA compliance requests. The operation is irreversible and prevents any future attempts to re-add a person with the same identifier (email or ID).
