<!--IssueSummary end-->
Add a REST API endpoint that restores a soft-deleted organization (transitions it from `soft_deleted` back to `active`) by exposing `Organizations::RestoreService` (from #599343). Admin-only.
## Dependency
Blocked by #599343, which provides:
- `Organizations::RestoreService` (the service this endpoint calls), and
- the `:restore_organization` policy ability (admin-only) used for `authorize!`.
The `route_setting :authorization, permissions: :restore_organization` also relies on the granular-token permission registry defined in #599344 (`config/authz/permissions/organization/restore.yml`). Whichever of #599344 / this issue lands first should add that file.
## Background
The Organizations REST API (`lib/api/organizations.rb`) currently exposes only `POST /organizations` (create). There is no member route yet. The Groups API already has a direct template for this in `lib/api/groups.rb` — `POST /groups/:id/restore` calling `Groups::RestoreService` — which this endpoint mirrors. The `find_organization!` helper (`lib/api/helpers.rb`) already loads an organization and enforces `:read_organization`.
## Implementation plan
### 1. Endpoint — `lib/api/organizations.rb`
Add a member route inside the existing `resource :organizations` block, mirroring the create action's style (`route_setting :lifecycle, :experiment`, `route_setting :authorization`, `ServiceResponse` handling):
```ruby
desc 'Restore a soft-deleted organization' do
detail 'This feature was introduced in GitLab 19.1.'
success Entities::Organizations::Organization
tags %w[organizations]
end
params do
requires :id, type: Integer, desc: 'The ID of the organization'
end
route_setting :lifecycle, :experiment
route_setting :authorization, permissions: :restore_organization, boundary_type: :instance
post ':id/restore' do
organization = find_organization!(params[:id])
authorize! :restore_organization, organization
response = ::Organizations::RestoreService
.new(organization, current_user: current_user)
.execute
if response.success?
present response[:organization], with: Entities::Organizations::Organization
else
render_api_error!(response.message, :bad_request)
end
end
```
Notes:
- `find_organization!` returns `not_found!` for unknown IDs and enforces `:read_organization`; soft-deleted organizations remain readable (no default scope hides them), and `find_by_id` finds them.
- `authorize! :restore_organization` enforces the admin-only ability from #599343 — non-admin owners who can read the org are still rejected.
- The existing `Entities::Organizations::Organization` is reused as-is for the response; no entity changes needed.
### 2. Documentation — `doc/api/organizations.md`
Add a "Restore an organization" section after "Create an organization", documenting:
- `POST /organizations/:id/restore`
- the `id` attribute,
- a `curl` example and a sample response (the organization entity),
- the experiment/admin-only note.
### 3. Request spec — `spec/requests/api/organizations_spec.rb`
Add `describe 'POST /organizations/:id/restore'` covering:
- Unauthenticated request → `401`.
- Authenticated non-admin (e.g. org owner) → `403`.
- Unknown organization ID → `404`.
- Admin restoring a `soft_deleted` organization → `201`/`200` with the organization payload, state becomes `active`.
- Admin restoring a non-`soft_deleted` organization → `400` with the service error message.
## Out of scope
- `Organizations::RestoreService` itself - #599343+
- The `OrganizationRestore` GraphQL mutation - #599344+
- Admin Area UI — separate issue.
## Acceptance criteria
- [ ] `POST /organizations/:id/restore` exists and calls `Organizations::RestoreService`.
- [ ] The endpoint is admin-only via `authorize! :restore_organization` and declares the matching granular-token `route_setting :authorization`, consistent with the create endpoint.
- [ ] Restoring a soft-deleted organization returns the organization and transitions it to `active`.
- [ ] Validation/permission failures return appropriate HTTP status codes (`400`/`403`/`404`).
- [ ] The endpoint is behind the `experiment` lifecycle marker.
- [ ] REST API docs (`doc/api/organizations.md`) document the new endpoint.
- [ ] Request spec covers auth, success, validation failure, and not-found cases.
