Replace the roles of a membership

PUT /v1/organizations/{org_id}/memberships/{membership_id}/roles · permission organizations:write

Replaces the membership's manually assigned roles with role_ids (an empty array removes them). Roles granted by IdP mappings or directory sources are not changed. If role_version is given it must equal the membership's current version, otherwise 409 conflict. The last admin's admin role cannot be removed. The write is audited as organization_membership.updated.

Request

Field Type Required Description
org_id path yes Organization ID (org_…).
membership_id path yes Membership ID (mem_…).
role_ids string[] yes The full set of role IDs (rol_…), at most 50.
role_version integer no Expected membership version (1 or more).
revoke_sessions boolean no Default true. Chooses whether removing a privileged (is_privileged) role revokes the user's refresh token families in this organization context (plan §17.4); false turns this off. In this release the choice is only recorded in the revoke_sessions metadata of the organization_membership.updated audit record and no session is revoked; the revocation is planned (planned) in the authentication service.

Response

200 OK with the updated membership and its ETag.

Errors

HTTP code When
404 not_found The membership does not exist in this organization.
403 role_not_assignable A role is not an environment role or a role of this organization.
409 conflict role_version does not match the membership's current version.
409 last_org_admin The change would leave the organization without an active admin.
422 validation_failed role_ids is missing or invalid, or role_version is below 1.
401 unauthenticated The credential is missing, invalid or revoked.
403 insufficient_permissions The credential lacks the required permission. Assigning a privileged (is_privileged) role also requires roles:write; without it nothing is written and required_permissions lists both permissions.
429 rate_limited The rate limit was exceeded; retry after the Retry-After period.
503 service_unavailable A dependency is temporarily unavailable; retry after the Retry-After period.
