+= Restcomm JAVA Sdk - Notifications
+
+[[Notifications]]
+== Notifications
+
+A *Notification* resource represents a single log entry made by RestComm while handling your calls or your use of the Restful APIs. It is very useful for debugging purposes. The Notifications list resource represents the set of notifications generated for an account.
+
+
+From here onwards, by a Notification, we refer to a Notification Resource Object
+
+=== Fetching a Notification 
+
+A Notification with a given Sid can be fetched by the following code snippet
+....
+  String Sid;
+  .
+  .
+  .
+  Notification CallNotification = Notification.getNotification(Sid);
+....
+
+=== Accessing the Fetched Notification
+
+A Field of a Notification Object can be accessed by using the corresponding getMethod for that Field
+....
+  String Message;
+  Message = CallNotification.getMessage_text().
+....
+
+==== List of Fields
+[cols=",",options="header",]
+|===============================================================================================================================================================================================================================
+|Property |Method 
+|Sid | getSid().
+|DateCreated |getDate_created().
+|DateUpdated |getDate_updated().
+|AccountSid |getAccount_sid().
+|CallSid |getCall_sid().
+|ApiVersion |getApi_version().
+|Log |getLog().
+|ErrorCode |getErrorCode().
+|MoreInfo |getMore_info().
+|MessageText |getMessage_text().
+|MessageDate |getMessage_date().
+|RequestUrl |getRequest_url().
+|RequestMethod |getRequest_method().
+|RequestVariables |getRequest_variables().
+|ResponseHeaders |getResponse_headers().
+|ResponseBody |getResponse_body().
+|Uri |getUri().
+|===============================================================================================================================================================================================================================
+
+== Fetching List of Notifications
+
+=== Fetching the Default List
+
+The Default Notifications List can be fetched by using the following code
+
+....
+  NotificationList List = NotificationList.getList();
+....
+
+=== Fetching a Filtered List
+
+A Filtered Notifications List can be fetched by using the getFilteredList() method of the class NotificationList
+
+....
+  NotificationList List = NotificationList.getFilteredList().ErrorCode("1").MessageText("Hello World").Filter();
+....
+
+The above mentioned code snippet fetches the Notifications with ErrorCode = 1 and MessageText = Hello World
+
+==== List of FilterParameters
+[cols=",",options="header",]
+|===============================================================================================================================================================================================================================
+|Parameter |Method 
+|StartTime |StartTime().
+|EndTime |EndTime().
+|ErrorCode |ErrorCode().
+|MessageText |MessageText().
+|RequestUrl |RequestUrl().
+|===============================================================================================================================================================================================================================
+
+In addition to these, the regular Paging paramters can also be used similar to the FilterParameters
+....
+ NotificationList List = NotificationList.getFilteredList().PageSize("1").Filter().
+....
+
+==== List of PagingParameters
+[cols=",",options="header",]
+|===============================================================================================================================================================================================================================
+|Paramter |Method 
+|Page |Page().
+|NumPages |NumPages().
+|PageSize |PageSize().
+|Total |Total().
+|Start |Start().
+|End |End().
+|===============================================================================================================================================================================================================================
+
+== Accessing the Fetched NotificationList
+
+The size of the Fetched List can be known by
+....
+  int size = CallNotification.size();
+....
+
+The a Notification from the fetched NotificationList Object can be obtained by
+....
+  Notification a = CallNotification.get(1);
+....
+
+== Additional Paging Information
+We can also access the Additional Paging Information by using the Methods of NotificationList
+....
+  String Uri;
+  Uri = CallNotification.getpreviouspageuri();
+....
+
+The API returns URIs to the next, previous, first and last pages of the returned list as shown in the table below:
+
+=== Request Parameters
+
+[cols=",",options="header",]
+|============================================================
+|Parameter |Method
+|Uri |geturi().
+|Firstpageuri |getfirstpageuri().
+|Nextpageuri |getnextpageuri().
+|Previouspageuri |getpreviouspageuri().
+|Lastpageuri |getlastpageuri().
+|============================================================
+
+NOTE: The Default Account from which we fetch the Notifications is the Main Account.
+
+If we want to change the Default Account to any specific SubAccount , use the following method before Fetching the Notification(s)
+....
+  NotifactionList.SubAccountAccess(SubAccountSid);
+  NotificationList List = NotificationList.getList();
+....
