Overview
Customers
Section titled “Customers”OPTIONAL sub-accounts. Segregate deposit addresses per end-user (your own customers). A Customer is a first-class, queryable handle, give each end-user one Customer, then create wallets with customer_id to attribute deposits. Skip it entirely if you don’t need per-user segregation (addresses then belong to the workspace itself). Balances stay at the workspace level; the Customer is used for ownership/attribution. external_ref is YOUR opaque id, never put PII in it.
