title: Invoke AWS Step Function from AWS Lambda Proxy (AWS API Gateway) .NET SAM Template
body: <p>I have a AWS API Gateway, deployed using SAM template. The API request comes to the    Proxy Lambda Function. From there I need to call a AWS Step Function which invokes multiple Lambda Functions. I have multiple Solutions. Following Microservices pattern. Need to call one microservice from another. Each Microservice is in a seperate solution and the startup project is a ClassLibrary(.NET Core 2.1). Using SAM template and deploying it via AWS Toolkit for Visual Studio. Not using Fargate Containers and WebApi projects. Need to coordinate between API Gateways.</p>
