WSO2 BPS has a complete management API to check which processes are deployed, running and completed instances, variables, values and more. The available methods can be found at ProcessManagement, InstanceManagement and PackageManagement WSDLs.
These three services can be invoked through any web service client.
Note
It is mandatory to authenticate the user before invoking management services.
Sample Client
Shown below is the source for a sample management client which uses default username (admin), password (admin) to login to the BPS server and retrieve the process list. You can find the sample pom file to create a jar here.
