Changes a customer's details. Send only what you want to change. The body has the same fields as Create customer.

What's replaced and what's kept

• A field or block you leave out keeps its current value.
• To clear a text field, such as phone, send an empty string ''. null is ignored and keeps the old value.
• organisation: null removes the organisation.
• shipping_address: null removes the shipping address and sets same_as_billing_address to false.
• same_as_billing_address: true copies the billing address to the shipping address. Any shipping_address you send is then ignored.
• tag_list replaces all the customer's tags. Send [] to remove every tag. Leave it out to keep them. To change only the tags, use Replace customer tags.
• customer.status changes the status. Send active or dormant. Other values are ignored without an error, and the status doesn't change.

The response is the updated customer, without tags.
