Is there any Rest Api by which we can know the status of the running process instance or to check if it's completed

Hi,
Would be helpful if there is any rest api by which we can check the status of the process instance.
I need to look for the completion of the workflow instance and then throw message that the instance which started with the business key ‘X’ is completed.

Hi,

What about this [1] API?

regards

Rob
