Data flow: Sending and receiving work data from a 
BlackBerry Dynamics
 app using 
BlackBerry Dynamics
Direct Connect

This data flow describes how data travels when a 
BlackBerry Dynamics
 app accesses an application or content server in your organization using 
BlackBerry Dynamics
Direct Connect
 in its most basic configuration. In this configuration, the 
BlackBerry Proxy
 server is directly accessible to the Internet on port 17533. Installation of a 
BlackBerry Connectivity Node
 is recommended when configuring 
BlackBerry Proxy
 servers for 
Direct Connect
. For other configuration options, see Deployment options.
Direct Connect data flow
  1. The user opens a 
    BlackBerry Dynamics
     app to access work data.
  2. The 
    BlackBerry Dynamics
     app establishes a TLS connection to the 
    BlackBerry Proxy
     server on port 17533.
  3. BlackBerry Proxy
     authenticates to the 
    BlackBerry Dynamics
     app using its server certificate. 
    BlackBerry Proxy
     validates the app using a MAC key with a session key known only to 
    BlackBerry Proxy
     and the app.
  4. The 
    BlackBerry Dynamics
     app creates a connection to the app server behind the firewall inside the previous connection. When the secure end-to-end connection is established, work data can travel between the device and application or content servers behind the firewall using 
    BlackBerry Proxy
    .
