Node service monetization

Count usage of a particular service, saving history in a database table. Each time a GET call is made on an API endpoint, write the transaction details to a 'TransactionHistory' table. Record the user name, application API key, and timestamp.

var payload = {
 
    user_name: platform.session.user.email,
    api_key: platform.session.api_key,
    timestamp: (new Date()).toString()
};
 
platform.api.post("db/_table/TransactionHistory", {"resource": [payload]}, '', function(body, response){
 
    console.log(response.statusCode + " " + response.statusMessage);
    event.setResponse(JSON.parse(body), response.statusCode, 'applicaton/json');
});
