Hello, I just purchased some PHP code that is supposed to connect to UPS for the Online Address Validation Tool. The code, however, uses cURL. when i enter aal fields ups_userid, ups_password, ups_xml_access_key, ups_shipper_number are correct then it return response_status_code = 0 but it should return response_status_code = 1 Array ( [response_status_code] => 0 [error_description] => Invalid Access License number ) if any one have done work on it or can solve this problem please provide some solution. code is given below.
