In this blog, we’ll see how to easily synchronize **Google Calendar events** with the ** Syncfusion .NET MAUI Scheduler** control. **Note:** Before proceeding, please read the [Getting Started with .NET MAUI Scheduler documentation](https://help.syncfusion.com/maui/scheduler/getting-started) . Let’s get started! ## Connect Google Cloud service You can use the **Google Calendar API** to connect with Google Calendar programmatically in your .NET MAUI app. Follow these steps to create a project in Google Cloud and enable **Google Calendar API**. ### Step 1: Log in to the Google Cloud console First, log in to the [Google Cloud console](https://console.cloud.google.com/) . ### Step 2: Create a new project Create a new project by clicking **Select a Project –**> ** New Project**. ![Create new .NET MAUI project on Google Cloud console](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Create-new-.NET-MAUI-project-on-Google-Cloud-console-1.png) Now, give the project a name and then click **Create**.![Name the Created Project on Google Cloud](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Name-the-Created-Project-on-Google-Cloud.png) ### Step 3: Enable the Google Calendar API In the navigation menu, choose **APIs & Services** –**>** ** Library**.![choose APIs & Services and then Library](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/choose-APIs-Services-and-then-Library.png) Now, search for the **Google Calendar API** in the library menu. Click on it, then click the **Enable** button to enable the Calendar API for your project.![Enable the Google Calendar API](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Enable-the-Google-Calendar-API-2.png) ### Step 4: Create API key credentials After enabling the **Google Calendar API**, click the** APIs & Services** tab and navigate to the ** Credentials** option from the menu. Now, click the **Create credentials** button. Select the created project, select the ** API Key** option, and copy the API key**.**![Create the API key credentials](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Create-the-API-key-credentials.png) You have now created your **Google Calendar API key**, which you can use in your .NET MAUI app to authenticate with the Google Calendar API service. ### Step 5: Install the required NuGet package to use the Google Calendar service In your .NET MAUI project, use the **NuGet Package** ** Manager** to install the [Google.Apis.Calendar.v3](https://www.nuget.org/packages/Google.Apis.Calendar.v3) package. Refer to the following code example to utilize the **Google Calendar API key** from the Google Cloud service. ``` // Initialize the Google Calendar service with the API key CalendarService service = new Calendar-Service(new BaseClientService.Initializer() { ApiKey = "Use the API key of your created project", ApplicationName = "Use the name of your created project" }); ``` ## Fetch Google Calendar events Once the Google Calendar API is enabled, you can use the **CalendarService** to access events by using the ** Calendar ID** of your Google Calendar. To do so, follow these steps: 1. Navigate to the **Google Calendar**. Click the ** Settings**icon and select ** Settings** from the dropdown.![Google Calendar](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Google-Calendar-3.png) Google Calendar 2. In the settings, locate the **ID** of your Calendar, as shown in the following image.![Google Calendar setting](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Google-Calendar-setting-1.png) Google Calendar setting 3. Refer to the following code example to see how to use the **Calendar ID** and fetch events from Google Calendar.``` string calendarId = "Use Google Calendar Id"; // Define a DateTime range to retrieve events DateTime startDate = DateTime.Now; DateTime endDate = DateTime.Now.AddDays(90); // Define the request to retrieve events EventsResource.ListRequest request = service.Events.List(calendarId); request.TimeMin = startDate; request.TimeMax = endDate; request.ShowDeleted = false; // Execute the calendar service request and retrieve events Events events = request.Execute(); ``` ## Synchronizing Google Calendar events with .NET MAUI Scheduler Next, we’ll look at how to load the **Google Calendar events** in the ** Syncfusion .NET MAUI Scheduler**control. ### Step 1: Register the handler for Syncfusion Core Register the handler for Syncfusion Core in the **MauiProgram.cs** file. ``` public static MauiApp CreateMauiApp() { var builder = MauiApp.CreateBuilder(); builder.ConfigureSyncfusionCore(); } ``` ### Step 2: Create an appointment model class Create an **Appointment** data model class that encapsulates the crucial appointment details. This class will be used to create appointments in the **.NET MAUI Scheduler**. Refer to the following code example. **Appointment.cs** ``` public class Appointment { /// /// Gets or sets the value to display the start date. /// public DateTime From { get; set; } /// /// Gets or sets the value to display the end date. /// public DateTime To { get; set; } /// /// Gets or sets the value to display the subject. /// public string EventName { get; set; } /// /// Gets or sets the appointment background color. /// public Brush Background { get; set; } } ``` ### Step 3: Create the Scheduler appointments from Google Calendar Let’s create the Scheduler appointments from the Google Calendar events. Refer to the following code example to retrieve Google Calendar events. **SchedulerViewModel.cs** ``` public ObservableCollection Appointments { get; set; } = new ObservableCollection(); // Execute the calendar service request and retrieve events Events events = request.Execute(); foreach (Event appointment in events.Items) { Appointments.Add(new Appointment() { EventName = appointment.Summary, From = Convert.ToDateTime(appointment.Start.Date), To = Convert.ToDateTime(appointment.End.Date), }); } ``` ### Step 4: Bind appointments to the Scheduler Initialize the .NET MAUI Scheduler control. **MainPage.xaml** ``` xmlns:scheduler="clr-namespace:Syncfusion.Maui.Scheduler;assembly=Syncfusion.Maui.Scheduler" ``` Finally, bind the custom **Appointments** to the Scheduler’s [AppointmentsSource](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.Scheduler.SfScheduler.html#Syncfusion_Maui_Scheduler_SfScheduler_AppointmentsSource) using the [appointment mapping](https://help.syncfusion.com/maui/scheduler/appointments#scheduler-appointment-source-mapping) feature. Refer to the following code example to bind the **AppointmentsSource** property from the ** SchedulerViewModel** class. **MainPage.xaml** ``` ``` Refer to the following images. ![Events in Google Calendar](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Events-in-Google-Calendar-1.png) Events in Google Calendar ![Synchronizing Google Calendar Events in the Syncfusion .NET MAUI Scheduler](https://www.syncfusion.com/blogs/wp-content/uploads/2023/10/Synchronizing-Google-Calendar-Events-in-the-Syncfusion-.NET-MAUI-Scheduler-1.png) Synchronizing Google Calendar Events in the Syncfusion .NET MAUI Scheduler ## GitHub reference For more details, refer to [Synchronizing Google Calendar events in .NET MAUI Scheduler](https://github.com/SyncfusionExamples/Load-Google-Calendar-events-in-.NET-MAUI-Scheduler) on GitHub. ## Conclusion Thanks for reading!
