You are using "nics/setupnetworks", which is the old and deprecated
method. You should try to use "hosts/{host:id}/setupnetworks" instead.
For example, with curl:

---8<---
#!/bin/bash -ex

url="https://engine-fqdn/api"
user="admin at internal"
password="..."

curl \
--verbose \
--request POST \
--cacert /etc/pki/ovirt-engine/ca.pem \
--user "${user}:${password}" \
--header "Content-Type: application/json" \
--header "Accept: application/json" \
--header "Version: 3" \
--data '
{
  "modified_bonds": {
    "host_nic": [
      {
        "name": "bond0",
        "bonding": {
          "options": {
            "option": [
              {
                "name": "mode",
                "value": "1"
              },
              {
                "name": "miimon",
                "value": "100"
              }
            ]
          },
          "slaves": {
            "host_nic": [
              {
                "name": "eth1"
              },
              {
                "name": "eth2"
              }
            ]
          }
        }
      }
    ]
  }
}
' \
"${url}/hosts/5d6741c0-d5f3-44f6-9ff5-fce2a3e8fe02/setupnetworks"

Other than that you request looks correct and I think it should work.

NOTE: Consider using "/ovirt-engine/api" as "/api" won't work with
version 4 of the engine.
