+Event Name
+##########
+
+ .. container:: paragraph
+
+ Any event defined in APEX has to be unique. The "name" of
+ of an event is used as an identifier for an ApexEvent. Every
+ event has to be tagged to an eventName. This can be done in different
+ ways. Either the actual event can have a field called "name". Or, the
+ event has some other field that can act as the identifier, which can be
+ specified using "nameAlias". But in other cases, where a "name" or "nameAlias"
+ cannot be specified, the incoming event coming over an endpoint can be
+ manually tagged to an "eventName" before consuming it.
+
+ .. container:: paragraph
+
+ The "eventName" can have a single event's name if the event coming
+ over the endpoint has to be always mapped to the specified eventName's
+ definition. Otherwise, if different events can come over the endpoint,
+ then "eventName" field can consist of multiple event names separated by
+ "|" symbol. In this case, based on the received event's structure, it is
+ mapped to any one of the event name specified in the "eventName" field.
+
+ .. container:: paragraph
+
+ The following code shows some examples on how to specify the eventName field:
