The diagram below describes the standard secure client API flow throughout the application life time:

• The very first action to perform is to initialize the client with clientInitialize().

• Then the L3 application needs to verify if key rollout is necessary (depending on its requirements). To do so the syncTime() function call be called to verify when the last key rotation happened. If the key rotation happened too long ago, syncExecute() must be called to perform the rotation.

• Once everything is set and ready, the L3 application can start the monitoring thread by calling the clientStart() function.

• When the application is about to quit, it should call clientTerminate() to gracefully shut down the monitoring service.
