Web Service:Issues

Web Services 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 your 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";

Announcement

Melissa Data is pleased to announce three new upgrades to our Data Quality Web Service to improve traffic flow. These improvements include:

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.

Extended Hours Tech Support

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.
