To use the Data Transfer API, you define a transfer and then initiate
it using the insert 
method. The transfer is defined in terms of one or more
applications whose data will be transferred, and can include application-specific parameters 
.
The following is a high-level summary of the transfer process:
- Determine the applications for which you want to transfer data.
- Define a  DataTransferresource that specifies the source and destination users and the applications for which to transfer data.
- Initiate the transfer by using the  insert()method .
For example, the following JSON request body transfers a calendar from
the source user (  SOURCE_USER_ID 
 
) to the destination user
(  DESTINATION_USER_ID 
 
). You can retrieve the user IDs for
each owner by calling the  user.get() 
method 
of the Directory API and providing their email address or email alias.
  { 
  
 "oldOwnerUserId" 
 : 
  
 " SOURCE_USER_ID 
" 
 , 
  
 "newOwnerUserId" 
 : 
  
 " DESTINATION_USER_ID 
" 
 , 
  
 "applicationDataTransfers" 
 : 
  
 [ 
  
 { 
  
 "applicationId" 
 : 
  
 "435070579839" 
 , 
  
 "applicationTransferParams" 
 : 
  
 [ 
  
 { 
  
 "key" 
 : 
  
 "RELEASE_RESOURCES" 
 , 
  
 "value" 
 : 
  
 [ 
  
 "TRUE" 
  
 ] 
  
 } 
  
 ] 
  
 } 
  
 ] 
 }
