Correct usage / syntax on "allow_update" field

[#1]

Hi Infoblox Experts!

I'm adding authoritative reverse zones using Powershell, using the below:

$data = '{"fqdn": "'+$Name+'","zone_format": "IPV4","view":"Internal","ns_group":"Internal","use_allow_update":true}'

Invoke-RestMethod -Uri $URL -Method Post -Credential $Creds -Body $data -ContentType "application/json"

The above works fine, however, when I want to use the "allow_update": field to appoint a named ACL, I can't find the right syntax to do that, always get 400 error.

Few examples I've tried but all fail e.g.:

1.

$data = '{"fqdn": "'+$Name+'","zone_format":

"IPV4","view":"Internal","ns_group":"Internal","use_allow_update":true,"allow_update":[{"namedacl":"TEST DDNS Updaters"}/"Allow"]}'

2.

$data = '{"fqdn": "'+$Name+'","zone_format": "IPV4","view":"Internal","ns_group":"Internal","use_allow_update":true,"allow_update":[{"namedacl":"TEST DDNS Updaters"}]}'

3.

$data = '{"fqdn": "'+$Name+'","zone_format": "IPV4","view":"Internal","ns_group":"Internal","use_allow_update":true,"allow_update":[{"namedacl":"TEST DDNS Updaters/Allow"}]}'

4.

$data = '{"fqdn": "'+$Name+'","zone_format": "IPV4","view":"Internal","ns_group":"Internal","use_allow_update":true,"allow_update":"TEST DDNS Updaters"}'

Could you give an example of how the "allow_update" should look like, preferably even a PS example please?

Thank you!

You need to supply a reference to the Named ACL, which means you need to run a GET first. For my example, the object reference for the Named ACL is 

namedacl/b25lLmRlZmluZWRfYWNsJDAuSW50ZXJuYWwgSG9zdHM:Internal%20Hosts

 POST /wapi/v2.10/zone_auth
 Content-Type: application/json

    {
      "fqdn":"test.org",
      "allow_update":[
          {
             "_ref":"namedacl/b25lLmRlZmluZWRfYWNsJDAuSW50ZXJuYWwgSG9zdHM:Internal%20Hosts"
          }
      ]
    }
