'API Gateway sign request with AWS SDK for .NET
I have an API in API Gateway whose Authorization type I have set to AWS_IAM to have API Gateway verify the signature on requests.
And restrict the API endpoint to only specific IAM users.
Now the problem is how can I consume this API from .NET? I cannot create/compute the signature by myself. Does the AWS SDK for .NET offer any helper or utility method/class to have the signature computed which I can attach as the HTTP header to my HTTP request?
Or can the API Gateway SDK for .NET make signed requests to my restricted API Gateway endpoint?
Solution 1:[1]
API Gateway doesn't yet support generated SDKs for .NET, so at this time your options are limited to:
- Find a SigV4 signer library for .NET
- Write your own SigV4 signer based on http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html
- Try to leverage the existing signing code in the AWS SDK for .NET http://aws.amazon.com/documentation/sdk-for-net/

I've created a NuGet package called AwsSignatureVersion4 which has been verified to work with the AWS API Gateway. Would love to hear what you think of it!
