I want to get the Microsoft email notification in my java program. I am using change notification of Microsoft Graph API to get notified whenever new email gets received. I have information like Secret ID, Value, client_id and tenant_id.
I have written a code to subscribe the emails but getting issues.
Code :
public static void main(String[] args) throws ParseException {
final ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
.clientId("**** client ID ****")
.clientSecret("**** client secret ****")
.tenantId("**** tenantID ****").build();
List<String> scope = new ArrayList<>();
scope.add(".default");
final TokenCredentialAuthProvider tokenCredentialAuthProvider = new TokenCredentialAuthProvider(scope,
clientSecretCredential);
final GraphServiceClient graphClient = GraphServiceClient.builder()
.authenticationProvider(tokenCredentialAuthProvider).buildClient();
final User me = graphClient.me().buildRequest().get();
Subscription subscription = new Subscription();
subscription.changeType = "created,updated";
subscription.notificationUrl = "https://webhook.azurewebsites.net/notificationClient";
subscription.lifecycleNotificationUrl = "https://webhook.azurewebsites.net/api/lifecycleNotifications";
subscription.resource = "/me/mailfolders('inbox')/messages";
subscription.expirationDateTime = OffsetDateTimeSerializer.deserialize("2024-03-20T11:00:00Z");
subscription.clientState = "SecretClientState";
graphClient.subscriptions().buildRequest().post(subscription);
}
}```
After starting the java application, I am getting error as,
