Deactivates one app of the authenticated client. The app stops authenticating requests as soon as the call returns, and everything already sent under it stays resolvable in your reports.

Removing an app frees its slot toward the 50 active app limit and frees its name for reuse.

An app that is not yours answers 404, exactly like one that never existed — the endpoint never confirms another client's identifier.

Authenticates with api-token alone — do not send an app-id header.
