V8 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 username, application key, and timestamp.

var payload = {
 
    username: platform.session.user.email,
    app_key: event.request.headers['x-dreamfactory-api-key'],
    timestamp: (new Date()).toString()
};
 
var result = platform.api.post("db/_table/TransactionHistory", {resource: [payload]});
 
if (result.status_code !== 200) {
 
    throw(JSON.stringify(result.content.error.message));
}
