# Library Element API

## Identifier (id) vs unique identifier (uid)

The identifier (ID) of a library element is an auto-incrementing numeric value that is unique per Grafana install.

The unique identifier (UID) of a library element uniquely identifies library elements between multiple Grafana installs. It's automatically generated unless you specify it during library element creation. The UID provides consistent URLs for accessing library elements and when syncing library elements between multiple Grafana installs.

The maximum length of a UID is 40 characters.

## Get all library elements

`GET /api/library-elements`

Returns a list of all library elements the authenticated user has permission to view. Use the `perPage` query parameter to control the maximum number of library elements returned; the default limit is 100. You can also use the `page` query parameter to fetch library elements from any page other than the first one.

Query parameters:

- **searchString** – Part of the name or description searched for.
- **kind** – Kind of element to search for. Use `1` for library panels or `2` for library variables.
- **sortDirection** – Sort order of elements. Use `alpha-asc` for ascending and `alpha-desc` for descending sort order.
- **typeFilter** – A comma separated list of types to filter the elements by.
- **excludeUid** – Element UID to exclude from search results.
- **folderFilter** – A comma separated list of folder ID(s) to filter the elements by.
- **perPage** – The number of results per page; default is 100.
- **page** – The page for a set of records, given that only `perPage` records are returned at a time. Numbering starts at `1`.

**Example Request**:

```http
GET /api/library-elements?perPage=10 HTTP/1.1
