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.

<source lang="javascript"> var payload = {

   user_name: platform.session.user.email,
   app_key: platform.session.api_key,
   time_stamp: (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));

} </source>
