Creating device trust / trust-domain through iControl REST Call(s)

Hey there

Currently I try to implement basic configuration through iControl REST calls. A personal deadend is building a device trust.

The API tells me how to do that: https://clouddocs.f5.com/api/icontrol-rest/APIRef_tm_cm_trust-domain.html. But it doens'nt work out. The same question has been asked here: https://community.f5.com/t5/technical-forum/rest-api-trust-domain-peer/td-p/164274. A solution is to send a POST with a tmsh command. Fair enough. But there hast to be a way to configure it the "right way" through proper REST calls. Any hints?

The URL I am calling:

• https://{{baseurl}}/mgmt/tm/cm/trust-domain/add-device

Here is my JSON body

{
    "ca-device": "{{f5ClusterPeer2}}",
    "device-ip": "{{f5MgmtIpPeer}}",
    "device-name": "{{f5ClusterPeer2}}",
    "device-port": "443",
    "device-username": "{{f5DeviceTrustUser}}",
    "device-password": "{{f5DeviceTrustPassword}}"
}

Note: I use Postman.

The response I get is this:

{
    "code": 409,
    "message": "01020066:3: The requested trust domain () already exists in partition Common.",
    "errorStack": [],
    "apiError": 3
}

Calling the "Root" resource in the URL responds this:

{
    "code": 403,
    "message": "Operation is not allowed on property group /cm/trust-domain/Root/add-device.",
    "errorStack": [],
    "apiError": 1
}

Edit:

I found this in the API doc: https://clouddocs.f5.com/api/icontrol-rest/APIRef_tm_cm_add-to-trust.html. But still doesn't work out wit this JSON body:

{
    "ca-Device": "true",
    "device": "{{f5ClusterPeer2}}",
    "deviceName": "{{f5ClusterPeer2}}",
    "port": "443",
    "username": "{{f5DeviceTrustUser}}",
    "password": "{{f5DeviceTrustPassword}}"
}
