REST API: Applications


An Application Resource (also referred to as a "TwiML Application" or "TwiML App") represents a collection of endpoints that return TwiML instructions to Twilio. TwiML Applications are most commonly used for the Voice SDKs to handle outbound calls, but can also be used to configure multiple phone numbers with the same set of TwiML endpoints.

The Applications list resource represents the set of an account's Twilio applications. You can POST to the list resource to create a new application. Note that accounts can contain at most 1000 applications.

Applications are useful for encapsulating configuration information that you need to distribute across multiple phone numbers. You can assign an ApplicationSid to an IncomingPhoneNumber to tell Twilio to use the application's URLs instead of the ones set directly on the IncomingPhoneNumber. So if you create an application with its VoiceUrl set to http://myapp.com/answer(link takes you to an external page), you can assign that application to all of your phone numbers and Twilio will make a request to that URL whenever a call comes in.
