Backendless SDK for .NET, Unity and Xamarin

Welcome to Backendless, a cloud-based serverless platform which significantly simplifies the process of development of web and mobile applications.

This SDK provides the client-side APIs which you can use in your app to take advantage of the Backendless platform functionality.

To get started you need to create a Backendless developer account at:

Once logged in, you will be prompted to create a backend application. Every application has a unique application ID, you will see it right on the main dashboard. Additionally, there is also API Key which must be used in your client application. The API key is also available from the main dashboard of the Backendless backend app. Make sure to use the Windows API Key.

When you obtain both application ID and API key, make sure to use them in the following API call to initialize your .NET/Xamarin app:

using BackendlessAPI;

Backendless.InitApp( "YOUR-APP-ID", "YOUR-API-KEY" );

Backendless has a ton of awesome functionality including:

  • Real-time Database (except for the .netstandard2.0 build)
  • Real-time Publish/Subscribe Messaging (except for the .netstandard2.0 build)
  • User Management (user registration, login, logout, password recovery)
  • Push Notification
  • File operations (upload, download, copy, move, delete)
  • Geo location
  • Custom business logic

All APIs can be secured with roles-based security. Also, you can create your own API services and deploy them into Backendless.

Be sure to check out API documentation available at:
