Google signin change language

Question

I've integrated a basic sign in like mentioned here:

https://developers.google.com/identity/sign-in/web/devconsole-project

Now I want to change the language of the button ("Sign in") without using a custom button with own image.

I've tried already this but it is not working:

<script src="https://apis.google.com/js/platform.js" async defer> {lang: 'de'} </script>

[like for other buttons using platform.js]

Thanks for any tips or maybe feedback from Google.

Answer 1

Try passing the language character code the following way: https://apis.google.com/js/platform.js?hl=de
