When you update a customer in the API, you cannot update the customer_id attribute. To update this attribute, use the BillPro UI.

Each time you update an address, it is saved as a new address. To update the customer's addresses, you must supply all the current addresses with any changes to them. If you do not supply an address, BillPro will remove it from the customer.

You must supply the addresses in the correct format. The format for the PUT request is not the same as the format in the response when you GET a customer.

In general, we recommend that you update addresses in the BillPro UI.

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.
