`In php i am trying to generate a online meeting url using microsoft teams.

We tried using the Microsoft graphs API, and were able to generate the token. However while submitting the request, we get a 403 Forbidden Error. We have registered our application in Azure and also given the required API permissions.

my API permssions also my tenant having authorized license

$auth_url = "https://login.microsoftonline.com/$tenantId/oauth2/v2.0/authorize";
    $params = [
        'client_id' => $clientId,
        'response_type' => 'code',
        'redirect_uri' => $redirectUri,
        'response_mode' => 'query',
        'scope' => 'offline_access OnlineMeetings.ReadWrite User.Read',
        'state' => '884766', // Optional: Prevent CSRF attacks
    ];

    $authUrl = $auth_url . '?' . http_build_query($params);

then in auth page

$clientId = TEAM_CLIENT_ID;
        $redirectUri = REDIRECT_URI;
        $tenantId = TENANT_ID;
        $clientSecret = CLIENT_SECRET;
        $tokenEndpoint = "https://login.microsoftonline.com/$tenantId/oauth2/v2.0/token";
        // Step 3: Exchange authorization code for an access token
        $client = new Client();
            $response = $client->post($tokenEndpoint, [
                'form_params' => [
                    'grant_type' => 'authorization_code',
                    'client_id' => $clientId,
                    'client_secret' => $clientSecret,
                    'code' => $authorizationCode,
                    'redirect_uri' => $redirectUri,
                    'scope' => 'user.read onlineMeetings.ReadWrite offline_access',
                ]
            ]);

            $responseData = json_decode($response->getBody(), true);
$accessToken = $responseData['access_token'];
            $refreshToken = $responseData['refresh_token'];
            $expiresIn = $responseData['expires_in'];

untill this i am getting the response.

$response = $client->post('https://graph.microsoft.com/v1.0/me/onlineMeetings', [
                'headers' => [
                    'Authorization' => 'Bearer ' .$accessToken,
                    'Content-Type' => 'application/json',
                ],
                'json' => [
                    'subject' => 'Test Meeting',
                    'startDateTime' => '2024-08-04T15:00:00Z',
                    'endDateTime' => '2024-08-04T16:00:00Z',
                ],
                'debug' => true // Enable Guzzle's debug output
            ]);


$data = json_decode($response->getBody(), true);
