### Update a plan

`PATCH /api/v1/profiles/{id}`

Partial update. Numeric and foreign-key fields can be cleared to null by sending null explicitly, which is distinct from omitting them.

- Authentication: manager session (JWT) or API token
- Permission: `prm_profiles_update` (Edit profiles)
- Risk: write
- Rate limit bucket: `t_mutate`

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `id` | path | integer | yes | Plan id. |

#### Note

Editing a plan does not re-provision the subscribers already on it. Their quota and window were written at activation time; a price or limit change applies to the next activation, not retroactively.
