   [
       {
           "Username": "myaccount@someone.com",
           "API-Key": "88b2b8e3d2b68b9cc4b945d81516v91d77k6g",
           "Zone": "myzone.xyz",
           "Entry": "myzone.xyz"
       },
       {
           "Username": "myaccount_1@someone.com",
           "API-Key": "55b2b8e3d2b68b9cc4b945d81516v91d77k6g",
