This action checks the ExtraView database for the existence of an issue.

user_id=username
&password=password
&statevar=item_exists
&id=nnnnn
&strict=no | yes
The output from the call is of the form Defect #nnnnn exists or Defect #nnnnn does not exist.
The optional parameter strict, with a value of yes, enforces the action to operate only on ALT_ID. If there is no match for the value of the ALT_ID in the specified ID parameter, then the message Invalid Id will be returned. This means that a matching ID value will be ignored.
