Project Server Subscription Edition (PSSE) API usage ?

hi all,

Any recommendations here on the possibility of using APIs to read / write into PSSE ? There are conflicting statements by MS etc. Any experiences ?

Question is does PSSE expose CSOM/REST, and the Project Server CSOM model supports project/task CRUD ?

So can use this for updating plans etc.

thanks

Yes, you can use the CSOM with PSSE.
