Introduction

The token inspector tool enables developers to check the Time to Live (TTL) and status (active/expired) for all tokens (including Enterprise tokens.) For Authorization Code Flow (3-legged OAuth) tokens, permission scopes will be displayed. You can fetch access token data using the /introspectToken endpoint or the Token Inspector Tool in the UI.
