There is no separate step to push the change out to holders; the role IS the grant. Adding a permission the role already carries is not an error, so a partially applied form can safely be submitted again. On success the response has no body (204). Failures: - `400` — `permissions` is missing or empty. - `404` — one of the permissions does not exist. - `422 IDE-1061` — a permission is reserved for machine credentials, so no role a person may hold can carry it; or the role itself is, so it takes no permission here. - `422 IDE-1066` — a permission is declared by a Lerian product, which alone decides the roles that hold it (this includes the M2M permission of a Lerian service's credential); the message names it. Grant the access by adding people to one of the product's roles, or to a group that role is granted to. Permissions earlier in the list are already added. - `503 IDE-0066` — the identity provider is unavailable (unreachable, too slow to answer, or failing). Nothing about the request was wrong; retry it later. ## OpenAPI ````yaml /pt/openapi/v3-current/AM-identity.yaml post /v1/roles/{id}/permissions openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: OpenAPI 3.1 surface for the Access Manager identity component. license: name: Lerian Studio General License title: Access Manager Identity API version: v1 servers: - url: https://identity.sandbox.lerian.net 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.
