# List Google Ads advertising languages

> <Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Returns the languages a campaign's ads can run in.

These are the codes the rest of the Google Ads endpoints accept as an ads language, for example `language_code` on [Estimate Google Ads cost per click](/api-reference/estimate-google-ads-cost-per-click). The list is the same for every app and changes only when Base44 adds a language, so you can cache it. The app does not need a Google Ads account.

This is limited to 120 requests a minute per app, shared with [Get Google Ads campaign launch draft](/api-reference/get-google-ads-campaign-launch-draft). Some workspaces have a different limit.

<Note>This endpoint accepts a personal API key from anyone who can view the app, including a read-only key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>
