Dashboard API to pull the RunStats for current deployment

Is there any Dashboard api to pull the current deployment, feature or initiative run stats like pass, fail, run, sev1 ,sev2 defects in PractiTest.

As far as I know, there’s no specific Dashboard API, but there are endpoints that let you pull run statistics of your project’s Tests / Runs and return a JSON with the counts of each run status. Those can be filtered by feature etc.
For defect metrics, you can use the Issues API to fetch and filter issues by severity.

What kind of dashboard are you trying to build and where?
