Get a customer using the id of the customer that was generated by the system.

The get customer response includes two identifiers: the system customer id, which is an integer, and the merchant's customer identifier or customer_id, which is an alphanumeric string.

To update a customer, after you get the customer, change the address format. See Update customer.

To create an order for the customer, set the order's customer_id to the system customerid.

The URLs in the examples in API documentation contain the {env} variable. Replace this variable with test for the test environment and app for the production environment.
