For all entities that support custom fields, the custom fields will be returned with the other fields, collected together into a ‘custom_fields’ block. For example:

curl -k -u <username>:<password> https://YOUR-SUBDOMAIN.administrateapp.com/api/v2/crm/accounts/24458

May return:

    "address_region": "AB",
    "is_supplier": false,
    ...
