Search people

Search people

Returns up to 1,000 people in a workspace who match a filter on segment membership and attribute values.

Note: For a set larger than the 1,000-person cap, export the people with POST /v1/exports/customers instead.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://api.customer.io
• Endpoint: POST /v1/customers
• Auth: send the header Authorization: Bearer $CUSTOMERIO_API_KEY
• Get a key: https://fly.customer.io/settings/api_credentials?keyType=app
• Docs: https://docs.customer.io/integrations/api/app/

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
