Hi @drammoorthy - yes, that should be fine! You may also need to write a brief summary of your takeaways. The # of CPE credits you get for attending should be equal to the # of hours of the learning. 

@drammoorthy agenda.  Receipt for the conference.  Some conferences do provide a form or certificate for CPEs.  Photo of nametag.

All should be fine.
If they kick it back for auditing, you can provide more.  I've done all the above.
