# searchCustomers

> Search for customers using a case-insensitive partial match across name, short name, email, and
external ID. Results are sorted by most recently active first. Best suited for human-driven
lookups (e.g. a search box) rather than precise programmatic resolution — use `customerByEmail`
or `customerByExternalId` for exact lookups. Optionally narrow the results with `filters`
(group membership, company, tenant, Slack channel and more). Requires the `customer:read` permission.
