Google: Updates language settings For more information, see Manage language settings (https: developers google com workspace gmail api guides language-settings) If successful, the return object contains the `display Language` that was saved for the user, which may differ from the value passed into the request This is because the requested `display Language` may not be directly supported by Gmail but have a close variant that is, and so the variant may be chosen and saved instead

Policy, approvals and errors

SDK function policy ID: google.gmail_users_settings_updatelanguage. Catalog operation: gmail.users.settings.updateLanguage. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.

Required provider scopes: ["https://www.googleapis.com/auth/gmail.settings.basic"]
