Hi,

Is there API to get only the description of every id using the GET /devices API.  
FYI: ( I would like to retrieve the id of each device but depending on the “description” )

json:  
[ {  
“id” : “291ae0e5956c69c2267489213df4459d19ed48a806603def19d417d004a4b67e”,  
“attributes” : [ {  
“name” : “ip\_addr”,  
“value” : “1.2.3.4”,  
“description” : “IP address”  
}, {  
“name” : “mac\_addr”,  
“value” : “00.01:02:03:04:05”,  
“description” : “MAC address”  
}, {  
“name” : “ports”,  
“value” : [“8080”, “8081”],  
“description” : “Open ports”  
} ],  
“updated\_ts” : “2016-10-03T16:58:51.639Z”  
}, {  
“id” : “76f40e5956c699e327489213df4459d1923e1a806603def19d417d004a4a3ef”,  
“attributes” : [ {  
“name” : “mac”,  
“value” : “00:01:02:03:04:05”,  
“description” : “MAC address”  
} ],  
“updated\_ts” : “2016-10-04T18:24:21.432Z”  
} ]

Hi @kacf ,

Thank you so much, So I guess I can use this to retrieve JWT for using in my API too, but will it retreive JWT Token after it expires in a week time also? I mean, will it auto renew in the process and retrieve the new JWT token, if old is expired

You always get a new JWT token from this end point. The status of the  
old token doesn’t matter.
