Is it possible to send a secure (signed) request to an Amazon API gateway using C#?

Question

I would like to make use of Amazon API Gateway and the security and throttling features that are advertised.

Is is possible to access them from a C# application?

At present, the only way I can see to make a secure, signed request (using the AWS Signature version 4) is to use the SDK/librariess generated by Amazon itself - which seems to be limited to javascript, ios and Android versions.

Is it possible to make a request using other methods?

Any information about how to make a connection from a desktop Java application or C# application would be very much appreciated.

Thanks!

API Gateway requests are normal requests to RESTful API . You should deploy your API and then create an Access Key in the dashboard and assign this key to your deployment. You can then use this Access Key in the X-Api-Key header so the server can authorize your HTTP Requests .

Here's more information on how to Create and use API Keys for Amazon API Gateway .

If you're looking to authorize and authenticate your users, then you need to use both, the X-Api-Key and SigV4 request signing using IAM Credentials as described in various AWS documents. Ideally you generate API Gateway SDK for your API and observe it's functionality. There's also a nice example project Secure Pet Store describing how to use IAM Credentials from Cognito to authorize and authenticate and possibly invoke Lambda using caller credentials .
