Detect a workflow session

Hi,

We have a 3rd party system and need integration between CRM and 3rd party using Javascript.

When a user starts any workflow let's say WorkflowA, we have to send a message to 3rd party system with CRM userid and entity record id.

1- Is there any way to detect workflow instances when a CRM user started it and get the status too("Success", "In Progress","Failed")?

2- Is there anyway to detect if a CRM user has started any workflow?

Thanks :)
