# Revoke access

> Remove a user from the share list. Takes effect immediately.

**`DELETE`** `https://api-datahub.octoparse.com/v1/data-apps/{app_id}/grants/{username}`

Authentication: API key required (`Authorization: Bearer <API Key>`). App author only; others get `404`.

Revocation takes effect immediately: read paths check the grant list on every request. There is no cache window.
