You can map JSON to specific class in Groovy using as operator   import groovy json JsonSlurper  String json            name    John        age   20        def person   new JsonSlurper   parseText json  as Person   with person        assert name     John      assert age    20

That response is a Map  with a single element with key  212315952136472   There s no  data  key in the Map  If you want to loop through all entries  use something like this   JSONObject userJson   JSON parse jsonResponse  userJson each   id  data - gt  println data link     If you know it s a single-element Map then you can directly access the link   def data   userJson values   iterator   next   String link   data link   And if you knew the id  e g  if you used it to make the request  then you can access the value more concisely   String id    212315952136472      String link   userJson id  link
