Research Amazon SaaS Integration Points

The request of this task is to research how we can write a NodeJS based function that will interact with the key aspects of a new user on boarding event via the AWS market place. But as part of that, we need to come up with a design in Node that will support the two key interaction points with AWS Marketplace: * Exchange token of customerID back to AWS and then store the AWS ID somewhere internally. Must call the ResolveCustomer AWS method
 * After registration, ABC app must call the GetEntitlement method to validate the account is active
 In short we plan to create a brand new registration form that we want the AWS marketplace to call when user clicks the “Sign up” button in AWS. So we need to figure out how to get AWS to pass the AWS User ID of the person who clicked the button to our form. Then we will need to capture that in the form along with additional user data and pass that to Node. In Node (and this is the scope of this research) after we insert the new user into our database, what do we call back to AWS and how? Based on preliminary research, there are these ResolveCustomer and GetEntitlement methods that both have to be called in our workflow. We can define when that happens later, but right now he needs to know how we should design the link between our NodeAPI and Amazon. What technology do we use to call those functions? Rest, SNS? Please research this concept and make some suggestions. Also please reach out to in your research to ensure what we are doing matches his plans. Then post a summary in this ticket of the recommendations. [login to view URL]
