The master branch is on 9.2, but there is a release branch for each version of Sitecore 9.x. I would like to get the 8.2 branch updated. But it is so far off from 9.x, it a hard lift to maintain both.

The xDB Peek exposes the current user's profile data in a JSON format and UI.

There are two APIs available:

Just visit VisitorDetails

Route: /Apis/v1/VisitorDetails Outputs the aggregation of the user's profile.

Route: /Apis/v1/ClearVisitorSession Clears the user's session is Sitecore. This has the same effect as timing the user's sessions out. This causes the session to be written to Mongo.

Route: /Apis/v1/MakeSessionHuman Tells Sitecore that the current session is real. This works well for UI/UX testing where you are checking xConnect data after the session is closed.

Pull the version from releases that matches your version. Install as an update package.
