Hi there!
I have to do something on Dynamics CRM Online side, that can process some parameters (while callback from external system) and do things in CRM.
I can get access token and refresh token for accessing CRM. (Exist registered Azure Active Directory application).
But what it will be? If I call web resource page in background of external system, javascript can't work and logic too doesn't work.
Logic can be implemented on external system side, but I need to do this on CRM side, by calling like a Get method with parameters (for example).
