# API Gateway examples using Amazon SDK for .NET
<a name="csharp_api-gateway_code_examples"></a>

The following code examples show you how to perform actions and implement common scenarios by using the Amazon SDK for .NET with API Gateway.

*Scenarios* are code examples that show you how to accomplish specific tasks by calling multiple functions within a service or combined with other Amazon Web Services services.

*Amazon community contributions* are examples that were created and are maintained by multiple teams across Amazon. To provide feedback, use the mechanism provided in the linked repositories.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.
