# Retrieve the entries of a specific policy import

`GET /api/2/policies/{policyId}/imports/{importedPolicyId}/entries`

Returns the entries (imported labels) of the policy import identified by the `policyId` path
parameter and the `importedPolicyId` path parameter.

The entries define which policy entries from the imported policy should be imported,
identified by their labels. An empty array means all implicit entries are imported.

Authentication (security requirement alternatives):

```json
[
  {
    "OpenIDConnect": []
  },
  {
    "NginxBasic": []
  },
  {
    "Bearer": []
  }
]
```

- OpenIDConnect: openIdConnect. OpenID Connect Discovery URL. The placeholder is replaced by Swagger UI when configured.
- NginxBasic: http (basic). Eclipse Ditto sandbox demo user (demo1 ... demo9) + password (demo)
- Bearer: http (bearer). A JSON Web Token issued by a supported OAuth 2.0 Identity Provider.

Parameters:

- `policyId` (path, string, required) - The ID of the policy needs to follow the namespaced entity ID notation (see [Ditto documentation on namespaced entity IDs](https://www.eclipse.dev/ditto/basic-namespaces-and-names.html#namespaced-id)).

The namespace needs to:
* conform to the reverse domain name notation
  Type: string

- `importedPolicyId` (path, string, required) - The ID of the imported policy needs to follow the namespaced entity ID notation (see [Ditto documentation on namespaced entity IDs](https://www.eclipse.dev/ditto/basic-namespaces-and-names.html#namespaced-id)).

The namespace needs to:
* conform to the reverse domain name notation
  Type: string

- `If-Match` (header, string, optional) - The `If-Match` header which has to conform to RFC-7232 (Conditional Requests). Common usages are:
  * optimistic locking by specifying the `ETag` from a previous HTTP response, e.g. `If-Match: "hash:a75ece4e"`
  * retrieving or modifying a resource only if it already exists, e.g. `If-Match: *`
  Type: string

- `If-None-Match` (header, string, optional) - The `If-None-Match` header, which has to conform to RFC-7232 (Conditional Requests). A common usage scenario is to modify a resource only if it does not yet exist, thus to create it, by specifying `If-None-Match: *`.
  Type: string

- `timeout` (query, string, optional) - Defines how long the backend should wait for completion of the request, e.g. applied when waiting for requested
acknowledgements via the `requested-acks` param. Can be specified without unit (then seconds are assumed) or
together with `s`, `ms` or `m` unit. Example: `42s`, `1m`.

The default (if omitted) and maximum timeout is `60s`. A value of `0` applies fire and forget semantics for
the command resulting in setting `response-required=false`.
  Type: string

Responses:

- 200: The request successfully returned. The entries are returned as a JSON array of label strings.

Content type: application/json

Type: Array<string>

Items:
  Type: string
  
  Label of a policy entry to import from the referenced policy.

```json
[
  "default",
  "import"
]
```

- 304: The (sub-)resource has not been modified. This happens when you specified a If-None-Match header which
 matches the current ETag of the (sub-)resource.

- 400: The request could not be completed. Possible reasons:

  * the `policyId` or the `importedPolicyId` does not conform to the namespaced entity ID notation (see [Ditto documentation on namespaced entity IDs](https://www.eclipse.dev/ditto/basic-namespaces-and-names.html#namespaced-id))

- 412: A precondition for reading or writing the (sub-)resource failed. This will happen for write requests, if you
specified an If-Match or If-None-Match header, which fails the precondition check against the current ETag of
the (sub-)resource. For read requests, this error may only happen for a failing If-Match header. In case of a
failing If-None-Match header for a read request, status 304 will be returned instead.
