Operations for creating and managing CallFire subscriptions that listen for account events
CallFire account events, such as TextSent or CallFinished, can be listened for (subscribed to) by registering a postback URI endpoint, either an email address or web service URL, that CallFire can publish the event info to. Subscription service is used for registering and managing these postback URI endpoints.
A typical use case would be for determining the status of a SendText request, which is an asynchronous operation. The status of the Text can be obtained either by polling the GetText / QueryText operations (pull strategy) or more efficiently by registering with Subscription Service a postback internet endpoint URL for receiving 'textsent' and 'textfinished' events to.
Currently supports Inbound-Text-Finished, Outbound-Text-Finished, Inbound-Call-Finished, Outbound-Call-Finished, Campaign-Started, Campaign-Stopped and Campaign-Finished events.
There is also the possibility to list all the Subscriptions that the user has created, asking for a " Max-Results"(Get no more than five, for example), and FirstResult, indicating which should be the first result, (for example if the user wants to get five of the first 10 Subscriptions).
