.NET IBM Watson + Lambda Integration

About

Ready to go .net core 2 lambda application for IBM Watson. Currently supporting two main services - Personal Insights, and Tone Analyzer.

Getting Started

Install .NET AWS Toolkit

Request API access @ https://console.bluemix.net and generate proper credentials for Personal Insights and Tone Analyzer APIs

When deploying the lambda ensure to enter the obtained API credentials, as such:

Create AWS API Gateway to target your created Lamba Functions.

In the method of the API Gateway -> Go To Integration Request -> Body Mapping Templates

Add content type "application/json"

If the method is "GET" add the following template

{

    "method": "$context.httpMethod",

    "body" : {
    #foreach($queryParam in $input.params().querystring.keySet())
    "$queryParam": "$util.escapeJavaScript($input.params().querystring.get($queryParam))" #if($foreach.hasNext),#end

    #end
  },  

    "headers": {

        #foreach($param in $input.params().header.keySet())

        "$param": "$util.escapeJavaScript($input.params().header.get($param))"

        #if($foreach.hasNext),#end

        #end

    }

}

If the method is "POST" then the following template

{

    "method": "$context.httpMethod",

    "body" : $input.json('$'),

    "headers": {

        #foreach($param in $input.params().header.keySet())

        "$param": "$util.escapeJavaScript($input.params().header.get($param))"

        #if($foreach.hasNext),#end

        #end

    }

}
