Including the App Client Key in your Proxima Requests
                
            
            
                                            
                                                        All requests that are sent to Proxima 
must include the unique Application Client Key that can be found in your Proxima Core App Browser (Admin ->  Proxima Core ->  App Browser).
The "Client Key" is used by Proxima to ensure all requests into the system are lined up with the proper Application (Proxima can support as many different applications on the same install as you wish).
The 
Client Key should be sent as the "username" portion in your 
HTTP Basic Authentication request.  Once a user has been "logged in" (see  
'(POST) - Login an existing User Account' for details), send the unique 
Session ID as the password (without a unique session identifier the client is limited to only a set of specific service requests, such as logging in, forgotten password, etc. - see the User Service documentation for the details).
