Good Morning,  
We are developing a solution using CIS2, eRS and PDS API. As part of CIS2 authentication we need to implement Back Channel Logout (BCL) in our application. I was wondering if any collages from the primary or secondary care setting manage to implement Back Channel Logout as part of their solution. Please see the URL below for more details.

Many thanks  
Mustansar

HI Mustansar, Adrian here - we’ve talked before. If no other suppliers have any sage advice for you on their implementations, I’m happy to discuss any questions you have from an implementation perspective if I can help.
