         Delete records from the project.
 
         Args:
             records: List of record IDs to delete from the project
+            arm:
+                the arm number of the arm in which the record(s) should be deleted.
+                (This can only be used if the project is longitudinal with more than one arm.)
+                NOTE: If the arm parameter is not provided, the specified records will be
+                deleted from all arms in which they exist. Whereas, if arm is provided,
+                they will only be deleted from the specified arm.
+            instrument:
+                the unique instrument name (column B in the Data Dictionary) of an
+                instrument (as a string) if you wish to delete the data for all fields
+                on the specified instrument for the records specified.
+            event:
+                the unique event name - only for longitudinal projects. NOTE: If
+                instrument is provided for a longitudinal project, the event parameter
+                is mandatory.
+            repeat_instance:
+                the repeating instance number for a repeating instrument or repeating event.
+                NOTE: If project has repeating instruments/events, it will remove only the
+                data for that repeating instance.
+            delete_logging:
+                provide a value of False ("keep logging") or True ("delete logging"). This
+                activity when deleting the record?" setting enabled by an administrator on
+                the Edit Project Settings page. The default value for PyCap is False
             return_format_type:
                 Response format. By default, response will be json-decoded.
