Guacamole get the key of the share link connection

[YOSRA SAADALLAH]

I'm working with guacamole 0.9.14 , i want to get the share link of the
connection. So i 'm using http.get and http.post to get the key .

At first , i got the token from

dns/guacamole/api/tokens

After that , i got the id connection and uuid session from
dns/guacamole/api/session/data/mysql/activeConnections?token=????

Now i want to get the key from :

dns/guacamole/api/session/tunnels/uuidconnection/activeConnection/sharingCredentials/idsession?token=???

But i have this result :

{
    "message": "No such tunnel.",
    "translatableMessage": {
        "key": "No such tunnel.",
        "variables": null
    },
    "statusCode": null,
    "expected": null,
    "type": "NOT_FOUND"}

It seems that the token has changed when i did the http.get to get the id
session and uuid connection.

Any suggestion?
