Ideal for customers who would like to use existing file formats and business processes to fulfill CSS switching obligations whilst helping you avoid costly system changes.

Option 2

Ideal for customers who would like to adopt new file message formats and business processes whilst using their existing technology.

Changes you'll need to make

  • You'll need to make changes to your systems and processes to submit messages that meet the new CSS data and structure requirements
  • Build new CSS files in your preferred format and issue CSS files for SwitchStream processing
  • Process CSS response files via SwitchStream service
  • Shippers will still need to undertake consequential process changes to support new switching arrangements

This SwitchStream option will provide consistency across all flows (CSS and Xoserve) as well as supporting a future roadmap for API messaging (beyond switching) across the industry.

Changes you'll need to make

  • You'll need to build new API messages in JSON format and call SwitchStream for processing 
  • You'll  need to transform your business processes to accept API responses from SwitchStream
  • Shippers will still need to undertake consequential process changes to support new switching arrangements
