How can I get a completion EMAIL only to the originator

I have created a API that goes out and get signatures from Multiple people.. Once completly signed I will create a package and sent to group with everything including a Signed Document. 

  Problem is once it is completed I (the Originator ) should only get an email  . Not all the signers..

using the API and this Parameter below.

     "completionEmails": "ALL"   has another parameter as NONE .. (Wandered the web looking) 

IS there another Paramter like OWNER,ORIGIN.. Anything

"emailOption": {
"sendOptions": {
"initEmails": "ALL",
"inFlightEmails": "ALL",
"completionEmails": "ALL"
}
},

   Now
