Helper method to map AWS Lambda environment variables to local variables. Used to run a local instance of a WebAPI API Gateway proxy project that uses resources where the physical ID is unknown, but mapped to environment variables through cloudformation.


  • Your CloudFormation stack name is the same as project name (apart from project name using underscore due to VS limitation)
  • All references to AWS resources have to be passed to application code via environment variables.
  • You have AWS access/secret keys with appropriate permissions set in local environment variables. These should cover the same permissions as your lambdas execution role.


  1. Install-Package MhLabs.AwsLambdaLocal
  2. In LocalEntryPoint.cs add this before var host = new WebHostBuilder():
LambdaEnvironment.MapToLocal(<<The region endpoint you're targeting, i.e RegionEndpoint.EUWest1>>).Wait();
