OpenNebula: instantiate a service template with Curl providing a service name

Question

In OpenNebula 5.4, I am able to instantiate a Service from a Service Template using Curl, but I don't know how to provide a service name. The website example works as expected:

curl http://127.0.0.1:2474/service_template/4/action -u 'oneadmin:opennebula' -v -X POST --data '{
  "action": {
    "perform":"instantiate"
  }
}'

Creates a service, with the same name than the service template. But if I run the same trying to add a parameter for that instantiate action (as done when performing an action on a given service), for example:

curl http://127.0.0.1:2474/service_template/4/action -u 'oneadmin:opennebula' -v -X POST --data '{
  "action": {
    "perform":"instantiate", 
    "params" : { 
       "name" : "new_name" 
     }
  }
}'

It ignores that param, resulting in the same as when running the previously mentioned Website example... I tried with 'name', 'service-name', 'service_name', but same result... Do you know how to do that, please? I think it probably is supported (as it is in their Java API), but not documented (as many other features).

In advance, thanks a lot and cheers

In the office we found a workaround:

it looks like it's not yet supported to send the parameter, so, it has to be performed a posterior action to update the newly created service, using the new Service ID (the full service JSON is returned in the body of the previous request): E.g: if the new service instantiated has ID 85, it would be:

curl http://127.0.0.1:2474/service/85/action -u 'oneadmin:opennebula' -v -X POST --data '{
"action": {
  "perform": "rename",
  "params": {
    "name": "some-service-name"
  }
 }
}'
