Hi @phenil,

Are you exchanging the authorization code within 10 minutes of obtaining it? Auth codes have a default active duration of only 10 minutes and can only be used once. If you've attempted to use the code after 10 minutes or attempted to use it more than once, you may encounter the error you are reporting.

 public function redirectToFitbit()

    {

        $query = http_build_query([

            'client_id' => '23RYH8',

            'redirect_uri' => 'https://uat.onehealthassist.com/fitbit/callback',

            'response_type' => 'code',

            'scope' => 'activity heartrate location profile ' . // Add additional scopes here

                'nutrition weight sleep social settings',

        ]);

            // Generate a unique code

        $code = uniqid();

        // Store the code in the session

        session(['fitbit_auth_code' => $code]);

        return redirect('https://www.fitbit.com/oauth2/authorize?' . $query);

    }

    public function handleFitbitCallback(Request $request)

    {

        $code = session('fitbit_auth_code');

        dd($code);

        // $code = $request->query('code'); // Retrieve the 'code' parameter from the query string

        // Prepare the form data

        $formData = [

            'code' => $code, // Use the 'code' parameter retrieved from the request

            'grant_type' => 'authorization_code',

            'redirect_uri' => 'https://uat.onehealthassist.com/'

        ];

        $response = Http::withHeaders([

            'Authorization' => 'Basic MjNSWUg4OjRiNGFiOTZhZDI4ZmZhMjg0M2M2OWZiN2MzNTEzZmRi',

            'Content-Type' => 'application/x-www-form-urlencoded'

        ])->asForm()->post('https://api.fitbit.com/oauth2/token', $formData);

        dd($response->json());

        // Check if the response is successful and contains the access token

        if ($response->successful() && $response->json() && array_key_exists('access_token', $response->json())) {

            $accessToken = $response->json()['access_token'];

            // Redirect to dashboard with access token as query parameter

            return redirect('/fitbit/dashboard?access_token=' . $accessToken);

        } else {

            // Log an error or handle the absence of access token as needed

            Log::error('Access token not found in Fitbit API response.');

            // You may also want to redirect with an error message

            return redirect('/fitbit/dashboard')->with('error', 'Access token not found. Please try again later.');
