# Remove a member

`DELETE /fapi/v1/organizations/{org_id}/memberships/{membership_id}` · called from the environment's sign-in host

Removes a member from the organization. The membership becomes `removed`, and the user's sessions and tokens for this organization are revoked; their account and their other organizations are not touched.

Requires the authenticated user's `__Host-idp_session` cookie with an exact `Origin`, or a first-party app's front API access token (`Authorization: DPoP <token>` with a DPoP proof; see [Front API access token](/docs/api/fapi/front-api-token)). The user must be an active member of the organization with the `idp_members:remove` permission. A user who is not a member gets `404 not_found`; a member without the permission gets `403 insufficient_permissions`.

Removing a member is a sensitive action: the user must have signed in within the last 5 minutes. Otherwise the answer is `401 step_up_required` with `WWW-Authenticate` naming `max_age=300`; sign the user in again with `maxAge: 300` and retry. This check comes before anything about the organization is read.

- You cannot remove your own membership here (`403 insufficient_permissions`).
- Only a member who holds the admin role can remove a member who holds a privileged role (`403 role_not_assignable`).
- The last active admin cannot be removed (`409 last_org_admin`).

With `@keenauth/js`: `await keenauth.organizations.removeMember(orgId, membershipId)`.

## Request

Headers:

## Errors

| Status | Code | When |
| --- | --- | --- |
| 400 | `malformed_request` | `If-Match` is malformed. |
| 401 | `unauthenticated` | No valid session cookie or token. |
| 401 | `step_up_required` | The user signed in more than 5 minutes ago. |
| 403 | `insufficient_permissions` | The user lacks `idp_members:remove`, or the membership is the user's own. |

| 403 | `origin_not_allowed` | The `Origin` does not match. |
| 404 | `not_found` | No such organization or membership for this user; an unknown, malformed or foreign identifier answers the same. |
| 409 | `last_org_admin` | The member is the organization's last active admin. |
| 409 | `organization_disabled` | The organization is disabled or pending deletion (`organization_pending_deletion`). |
