Kesha Williams explains how to write POST requests and deploy the service.

My sequel is up and running,…and the application's been deployed to the server.…So let's scroll down to line 44,…and look at the add application method.…And so this method is invoked on a POST request.…The next few statements I've enclosed in a try catch block…to catch and handle exceptions.…On line 47 I'm getting a database connection…and creating a statement.…On lines 48 through 50 I'm calling the execute update method…and I'm passing in a sequel statement…that inserts a new record into the TZA application table.…
