GET /themes

List all themes available in your workspace, including custom 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.
