# createCustomerCardConfig

> Creates a new customer card config. New configs are placed at the bottom of the list (order 100000) by default.

A maximum of 25 card configs can be created per workspace. Returns a `too_many_customer_card_configs` error if the limit is reached. The `key` must be unique within the workspace and is used in the request payload sent to your API URL.
