Develop an AWS Lambda function in Node.JS that reads JSON data from a web service and insert into DynamoDB

We are a education startup, building conversational training apps. We are trying use the IBM Tone Analyzer to analyse conversations in Text and store the results in DynamoDB. The project involves POSTing a paragraph of text to tone analyzer, storing the resulting JSON in a dynamoDB database. The project involves creating 3 things 1. Build GraphQL schema and queries to invoke a lambda function 2. Build a lambda function which is invoked by a GraphQL mutation that; a. POSTs conversation text to IBM Tone Analyzer and parse the JSON data b. Extract only document tones c. Writes the results to DynamoDB d. Returns full dynamoDB item to graphQL
