[fahim-ng]

public function configureTheme(Request $request)

{

$shop = Auth::user();

$themes = $shop->api()->rest('GET', '/admin/themes.json');

dd($themes);

$activeThemeId = "";

foreach($themes['body']->container['themes'] as $theme){

if($theme['role'] == "main"){

$activeThemeId = $theme['id'];

}

}

}
it returns 

"errors":"[API] Invalid API key or access token (unrecognized login or wrong password)
Please can any one help ?

Can you confirm that the API key and access tokens are both correct and active?

Yes, I set this in the environment file (SHOPIFY_API_KEY and SHOPIFY_API_SECRET) and utilise middleware (verify.shopify)

when route call.
I get the app user data from ($shop = Auth::user();) but  when get shopify api like $themes = $shop->api()->rest('GET', '/admin/themes.json');
it generates the Invalid API key or access token (unrecognized login or wrong password) error??

Thanks in Advance
