Query parameters

customer_idstring
id_type'id' | 'reference_customer_id'

How to interpret customer_id. Use id (the default) for the Numeral cust_* id, or reference_customer_id for your own id. Validated whenever present — passing an unknown value returns INVALID_REQUEST (400) even if customer_id is not also supplied.
