Beginning on April 23, U.S. EPA will be making updates to the Exchange Network Quality Assurance Server (QA Server). The QA Server currently provides a set of SOAP web services for synchronous and asynchronous XML schema validations, schematron validation, XML transformation via XSLT, and virus scanning.  

As part of this reengineering effort, the current QA Server will be updated and migrated to a new platform. Some older, unused functionality will be retired, but most of the current functionality will remain the same. Exchange Network partners typically interact indirectly with the QA Server when downloading schema validation reports for an Exchange Network data flow. Most partners should experience little to no impact from these changes. 

Here are some important highlights about the upcoming changes:

• The current endpoints for the QA Server will not change:
  • Test endpoint will remain https://tools.epacdxnode.net
  • Production endpoint will remain https://cdxtools.epa.gov
     
• Virus Scanning will no longer have its own Web Services Definition Language (WSDL). The method will be consolidated under the remaining WSDLs. Virus scanning can be performed synchronously with the Validator_v30.wsdl or asynchronously with the ValidatorEx_v30.wsdl.
   
• The Validator and ValidatorEx XSLT document transformation service and the Schematron validation service will be deprecated.
   
• 2 WSDLs will remain available for use:
  • Validator_v30.wsdl
  • ValidatorEx_v30.wsdl

Please see below for more information about the timeline and other considerations.
 
Timeline
The schedule for deploying the changes is as follows:

• Test Environment – April 23, 2021
• Production Environment – April 30, 2021

After changes deploy to the Test environment, you may test services using the new QA server. If you have any issues or questions, please contact the Exchange Network Node Help Desk (see contact information below).
