Data Quality Web Service
Version 2 Known Issues
 Important note:
We have upgraded to Windows 2003 and IIS 6. This is to increase
performance and reliability.
If you have started receiving any of these errors please review you
code for any improper posting practices.
“Error 400 - Bad Request”
“Error 403.1 - Execute Access Forbidden”
Our servers will not accept non-standard HTTP postings.
The action verb POST in your code specifically must be in upper case
or it will be rejected as an unauthorized application.
Also make sure you are not sending any hard returns which will also
be rejected as a bad request.
Here is an example of the incorrect posting method from a sample
program.
$CustomerID = "123456789";
$method = "post";
$host = "https://addresscheck.melissadata.net";
$usepath = "/v2/SOAP/Service.svc";
Melissa Data is
pleased to announce three new upgrades to our Data Quality Web
Service to improve traffic flow. These improvements include 1) Load
Balancing for All Servers, 2) Extended Hours Tech Support, and 3)
Server Maintenance Schedule.
Load Balancing for All Servers
We now have a Load Balancing solution in place so that you are no
longer required to poll across all servers. With this new upgrade,
you should no longer experience occasional downtime. Maintenance on
individual servers will go undetected by DQWS subscribers since the
load balancer will not send a record to an offline server.
Server Maintenance Schedule
Please be aware that Melissa Data will update its data files and
perform other server maintenance as required every Thursday at 11
a.m., Pacific Standard Time. There should be no interruption of
service during maintenance since no more then one server at any
given time will be taken offline for maintenance.
