Parse Json Response Property Transfer Value

How can i prase the programID from the below response as a property transfer to the next request.

{
"Name": "Referral Program",
"ProgramIdBackwardCompatible": true,
"_links": {
"self": {"href": "/platform/1"},
"programs": {
"href": "/program/1",
"title": "ABCD1"
},

When i do the property transfer it looks like this  "/platform/1" and i need "1"
