For enabling callback for the BPM Events server, use the bizpulse.server.callback parameter in the OEBPS_HOME\conf\bpmevents.conf file. By default, this parameter is set to false and the callback mechanism is disabled.
To enable callback for the BPM Events server, set the value to true, as shown in the following example:
bizpulse.server.callback = true
After changing the parameter’s value, restart BPM Events server to enable the Callback Adapter mechanism.
