Revoking the integration's access
Access can be revoked at any time, immediately, from within QuickBooks Online: Settings → Apps → Connected apps → Disconnect. Revocation takes effect at once and invalidates the stored tokens.
Because this integration runs locally and stores its tokens only on the director's own machine, deleting that local token file also ends access.
