# Suspend a member

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

Suspends a membership. The member keeps their roles but cannot act in the organization: their sessions and tokens in this organization's context are revoked, and they cannot select the organization until a member [reactivates](/docs/api/fapi/organizations/memberships/reactivate) them. Suspending a member who is already suspended answers the membership unchanged. The last active admin cannot be suspended (`409 last_org_admin`).

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 both the `idp_members:update_roles` and `idp_members:remove` permissions. A user who is not a member gets `404 not_found`; a member without both permissions gets `403 insufficient_permissions`. You cannot change your own membership here (`403 insufficient_permissions`), and only a member who holds the admin role can change a member who holds a privileged role (`403 role_not_assignable`).

With `@keenauth/js`: `await keenauth.organizations.suspendMember(orgId, membershipId, { expectedVersion: 3 })`.

## Request

Headers:

| Header | Required | Description |
| --- | --- | --- |
| `Idp-Client` | yes | SDK identifier. |
| `Origin` | yes, with the cookie | `https://<sign-in host>`. |
| `If-Match` | no | One version, `"<version>"`, from the member list. A version that does not match, or more than one version, returns `412 precondition_failed`. |

`org_id`: the organization identifier (`org_…`). `membership_id`: the membership identifier (`mem_…`).

No body.

## Response

`200 OK` with the membership (the same fields as an item of [the member list](/docs/api/fapi/organizations/memberships/list)) and `ETag: "<version>"`.

## Errors

| Status | Code | When |
| --- | --- | --- |
| 400 | `malformed_request` | `If-Match` is malformed. |
| 401 | `unauthenticated` | No valid session cookie or token. |
| 403 | `insufficient_permissions` | The user lacks `idp_members:update_roles` or `idp_members:remove`, or the membership is the user's own. |
| 403 | `role_not_assignable` | The member holds a privileged role and the user does not hold the admin role. |
| 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`). |
| 412 | `precondition_failed` | `If-Match` does not name the membership's current version. |
| 422 | `validation_failed` | The membership has been removed. |
| 503 | `service_unavailable` | Temporarily unavailable; retry after `Retry-After`. |
