Each item says whether it is your default tenant (`isDefault`, where your next sign-in goes), whether it is the tenant of the token making this request (`isCurrent`), and whether it has an active single sign-on provider (`ssoEnabled`). When you have no default tenant, every `isDefault` is false. Any authenticated member may call this for THEMSELVES; an `{id}` other than your token's subject is refused with `403 IDE-0057`. The e-mail is read from your own user record, never from the request. Read-only. The response carries `Cache-Control: no-store`. Failures: - `400` — `{id}` is not a UUID. - `401` — no bearer token. - `403 IDE-0057` — `{id}` is not you. - `404` — no such user. - `503 IDE-0060` — the identity provider is unavailable (unreachable, too slow to answer, or failing). Nothing about the request was wrong; retry it later. ## OpenAPI ````yaml /es/openapi/v3-current/AM-identity.yaml get /v1/users/{id}/tenants openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: >- OpenAPI 3.1 surface for the plugin-access-manager identity component. It exposes the M2M-gated declarations upsert (PUT /v1/declarations/{slug}), through which each plugin declares its own permissions/roles/M2M contract, and partner management (/v1/partners), through which a tenant administrator grants its own customers scoped API credentials. The remaining identity routes stay Fiber-native and are described by the separate OAS 2 document in the same folder. license: name: Apache-2.0 url: https://www.apache.org/licenses/LICENSE-2.0 title: Plugin Access Manager — Identity API version: v1 servers: [] security: [] tags: - description: >- M2M-only: each plugin declares its own permissions, roles and M2M contract, and the server reconciles them. name: Declarations - description: >- A tenant administrator's customers. Each partner holds what its credentials may DO (permissions, per product) and WHERE they may do it (scope, per product and dimension); an M2M application attached to one is confined to that intersection. Administrator-only: authorized on the "partners" resource, and every route resolves the owning organization from the caller's token. name: Partners paths: /v1/users/{id}/tenants: get: tags: - Users summary: List own tenants description: >- Lists the tenants your e-mail has an active account in, oldest tenant first.
