 # Connecting to REST API Services
 
-One of the "hidden" powers of Corona is the ability to connect to various online services to get data into your app. To accomplish this, a popular option is __REST__ (or RESTful) APIs which are based on standard HTTP protocols and are generally easy to authenticate.

 ## Authentication
 
 Most REST APIs require some form of verification or authentication, in particular if you're trying to add or update data. Authentication can occur in various ways, for example by passing the username and password as part of the domain name:
 
 ``````
-http://username:[email protected]/someapi/dosomething.json
+https://username:[email protected]/someapi/dosomething.json
 ``````
 
 In this example, the `username:password` method is a shortcut to using a headers table. Sometimes the username and password will be referred to as the "API Key" and "secret" and they may need to be encoded in some fashion such as [MD5][api.library.crypto].

 ## Making API Calls
 
-In Corona, your REST API calls are made via [network.request()][api.library.network.request]. For this API, you provide a URL, an HTTP "verb," a callback function to handle the completed request, and an optional table of information in which to handle headers and data passed to the server.
