Error when adding host using Zabbix API

[Judge_Dredd]

Hi All,
I am currently trying to automate the process of installing the agent on servers as well as adding the Host to Zabbix at the same time. I have come a little unstuck when I run the host.create command. The PowerShell code is as follows (lost it's formatting in the copying into this thread):
$request = @{
jsonrpc = "2.0"
method = "host.create"
params = @{
host = $hostName
interfaces = @{
type = 1 # 1 = agent
main = 1
useip = 1
ip = $hostIP
dns = $fqdn
port = 10050 # This is the default Zabbix agent port
}
groups = @{
groupid = "35"
}
templates = @{
templateid = "10081"
}
}
auth = $authToken
id = 2
} | ConvertTo-Json


The ConvertTo-Json creates the following Json:
{
"method": "host.create",
"params": {
"host": "CHC-G2-VDA12",
"groups": {
"groupid": "35"
},
"templates": {
"templateid": "10584"
},
"interfaces": {
"port": 10050,
"dns": "CHC-G2-VDA12.hot.co.nz",
"ip": "10.151.103.51",
"useip": 1,
"type": 1,
"main": 1
}
},
"id": 2,
"jsonrpc": "2.0",
"auth": "902ec9f6929bbd2628ad6d0c3015026e"
}


I then run the following:
$response = Invoke-RestMethod -Uri $apiEndpoint -Method Post -Body $request -ContentType "application/json-rpc"

The following is the error returned in $response
jsonrpc error
@{code=-32500; message=Application error.; data=No permissions to referred object or it does not exist!}

Does anyone have any ideas on what could be causing this?

Thanks in advance
Cheers

Okay - so I finally discovered that, yes, the message does give me a clue and after digging around in the permissions, the role in question did not have host.create permission however the error I get now is the following:

{code=-32602; message=Invalid params.; data=Incorrect arguments passed to function.}

This appears after passing the following JSON to the zabbix server:

{
"method": "host.create",
"params": {
"host": "HOTDCORDS01",
"groups": {
"groupid": "35"
},
"templates": {
"templateid": "10081"
},
"interfaces": {
"port": 10050,
"dns": "HOTDCORDS01.hot.co.nz",
"ip": null,
"useip": 1,
"type": 1,
"main": 1
}
},
"id": 2,
"jsonrpc": "2.0",
"auth": "e88a841d7636017f839b2ae55b3ee4c5"
}

I am not a coder so I have no idea how the JSON should actually look. Anyone recognise what may cause the above error

Thank in advance

But yet again, answered my own question by actually reading the code. The issue here was that "ip": null isn't going to work because I have stated "useip": 1 in the next line. The powershell command I was using didn't seem to be overly reliable in always returning the IP address so found a more reliable way.
