Enabling USPS address validation

To enable the integration, permissions must also be set correctly in Access Control. Use the Create Unvalidated Addresses access item under Property > Address in the Permissions tree. This permission is selected by default, allowing users to create addresses without validation. To enable address validation you must clear this permission.

  1. In the Configuration Editor, open the Resources configuration.
  2. Select the Address > Validation node and specify this information:
    Validation Enabled
    Set the value to True.
    Service URL
    Specify http://production.shippingapis.com/ShippingAPI.dll.
  3. Select the Address > Validation > Authentication > Credentials node.
  4. For the User Name attribute, specify your user ID for the API. You can obtain a user ID from the Postal Service.
