# Create access policy

Canonical page: https://docs.ovok.com/api/slim/policy/create-access-policy

`POST /v1/slim/policy`

Creates an access policy (role) in your project and assigns it to the listed practitioners. Use it to define a new role.

**Auth:** Bearer token for a practitioner, project admin or System Owner session. The caller's access policy must grant `AccessPolicy:create` and `ProjectMembership:update` (a project admin who holds no access policy skips this check).
**Scope:** The policy is created in the caller's project (from the token).

## Behaviour

- You cannot create a policy above your own rank. Ranks come from the policy name or its `basedOn` display: `System Owner` is the highest, then `Admin`, then every other policy. Project admins rank as System Owner.
- Ovok adds interactions the apps rely on:
  - `Consent`: `read`, `search`, `create`, `update`, always;
  - `DeviceUseStatement` and `EpisodeOfCare`: `read`, `search`, `create`, `update`, when the policy may create or update `Patient`;
  - `Provenance` and `AuditEvent`: `read`, `search`, when the policy is named `Admin` or `System Owner`.
- `members` are profile references such as `Practitioner/<id>`. Each listed member's membership in your project now points to the new policy, replacing the policy it held before. A member with no membership in your project is skipped.
- You cannot list a member whose current role ranks above yours. A member ranks as every policy their membership holds now (`accessPolicy` and any `access` entries), each ranked by its name. A project admin (`admin: true`) ranks as System Owner.
- The policy and the membership changes commit together. Past 49 membership changes they are written in two steps.
- The policy is then copied by name into each direct child project. A failed copy does not fail the request.
- Returns the created policy with its members, as in `GET /v1/slim/policy/{id}`.
