# GET /themes

List the themes available in the authenticated workspace. Use the returned `id` values as `themeId` in generation requests.

### What themes are

A theme controls the visual style of a generated Gamma — colors, fonts, backgrounds, and layout feel. Every workspace has access to Gamma's standard theme library plus any custom themes created in the workspace. Pass a theme's `id` as `themeId` in `POST /generations` or `POST /generations/from-template` to apply it.

### Pagination

Results are cursor-paginated. Each response includes `hasMore` (boolean) and `nextCursor` (string or null). To fetch the next page, pass the `nextCursor` value as the `after` query parameter. Use `limit` (1-50, default 20) to control page size. Use `query` to filter themes by name, or `type=standard|custom` to limit results to built-in or workspace themes. Keep the same `type` value across paginated requests.

## List themes

> Lists all themes available to the workspace, including standard themes and custom workspace themes.
