Playground

The Playground runs a live is-member check for one identifier from inside the app. Use it to confirm a realtime audience is behaving the way you intended before you point an integration at it.

Running a check

Navigate to Personalize → Membership → Playground.
Pick the identity field to look up (user_id or anonymous_id) and enter a value.
Optionally narrow to a single audience, which makes the verdict definitive either way. Leave it unset to sweep the workspace.
Run the check.

The verdicts come back as a list, named rather than shown as raw ids. You can copy the same request as a curl command to move straight to integration.

Two modes

Mode	How it authenticates	What you see
Debug	Your signed-in session, through Zeotap — no key needed	Every serveable audience with its verdict, `false` ones included, plus when each audience was last rebuilt and whether a verdict may be a false match
Live	A membership key (`pk_`) you supply, calling the API directly	Exactly what the API returns: the audiences this person is in, and nothing else

The two modes differ in shape, not only in detail. Debug is the internal read, so it lists non-members too and explains each verdict; the public API reports positives only and carries no such explanation. Neither is withholding anything by accident — see Response for why the public shape is the narrower one. Switch to Live to see precisely what your application will get.

Reading the result

An audience is missing in Debug. It is not currently serveable. The most common reason is that it has never been rebuilt — check Snapshots.
An audience is missing in Live. Either this person is not in it, or it is not serveable — the public response does not distinguish the two. Narrow to that one audience to get a definitive verdict, or compare against Debug.
Nothing comes back at all for an identifier you expect to match. Zeotap has no behaviour recorded against that identifier. Confirm the value is one your realtime events actually carry.
A verdict is flagged as a possible false match. The audience has a “has not done X” condition whose tracking is younger than its window, so the absence may not be real. See the freshness notes on the API reference.
