Hi, This can be achieved thru AWS Lambda with Amazon API Gateway. The idea would be to define a Lambda function which would get the input(payload) as defined in the project details, check if token and user are valid and depending upon the KPI-Id will do the DynamoDB call. The API Gateway will be used to define a GET/POST API which would take the input and trigger the AWS lambda function. Pleae contact me to discuss the details and I can start the work immediatly. I would require certian details regarding the DynamoDB tables/structure to make the db queries. I am assuming that the DynamoDB is already setup and the data is present. If this is not the case let me can we can work out on seting up the DB as well.

Hi, Lambda can be exposed via API either as REST or Websockets. Which one do you want? I believe it is most likely a REST API. Do you need just a GET API or POST too? GET will help you get data from DB and POST will allow saving the data? Do you need any type of security on top of API? Lastly, you have mentioned product and transaction in your queries. Where is this data coming from? Best regards Asif

Hi,I have worked extensively on building microservices using serverless architecture and can build your RESTful api using AWS lambda and Dynamodb as backend. I would be using AWS API Gateway which will invoke lamdba and do the resueat body validation. The business logic will fexth the data from dynamo db and provide API response from lambda to API gateway response. I need a simple AWS Lambda script that acts as an API endpoint. I assure you a quality and timely deliverable. Thanks Amit
