Hello,

I’m using GenieACS version 1.2.8 and I tried changing parameter attributes via API but had no success.

When trying to remove the subscriber entry from the ‘accessList’ attribute like that:

```
curl -i 'http://localhost:7557/devices/202BC1-BM632w-000000/tasks' -X POST --data '{"name":"setParameterAttributes","parameterAttributes":[{"name": "InternetGatewayDevice.LANDevice.1.WLANConfiguration.1.SSID", "notificationChange": false, "accessListChange": true, "accessList": ""}]}'
```

It is possible, but it appears to only be doable with provision scripts.

I found this discussion in your forum: But I’m lost on the exact syntax I have to use in my provision. Do I have to pass a special value in the “timestamp” field of my declare function? Thanks in advance!

Thank you for your response.

In case someone has the same problem, the correct syntax would be:

```
// restrict access
declare('InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnection.1.Username', {accessList: now}, {accessList: ['']});
// allow access
declare('InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnection.1.Username', {accessList: now}, {accessList: ['Subscriber']});
```

getParameterAttributes RPC use this script as well?
