Invalid API DeepL | ww.wp.xz.cn

The error occurs because DeepL no longer accepts the old authentication method. You now need to use the HTTP ‘Authorization’ header with your API key. Make sure TranslatePress is up to date and compatible with this method.

I have the plugin updated to the latest version, and it still won’t connect to the API.

Can you help me?

{“message”:”Legacy authentication method ‘form body’ is no longer supported. Please update to header-based authentication. Find more details in our docs: https://developers.deepl.com/docs/resources/breaking-changes-change-notices/november-2025-deprecation-of-legacy-auth-methods. You can find more info in our docs: https://developers.deepl.com/docs/getting-started/auth”}
