create stack api

I'm trying to create a stack using the orchestration API as referenced here. The particular method I'm calling is the POST to /v1/​{tenant_id}​/stacks.

I do not have trouble making POST requests in other parts of the API, and I am able to perform GETs to other methods in the orchestration API. However I repeatedly get 400 Bad Request as a response for the create stack method.

I am providing the stack_name parameter always. And I have tried using the template_url parameter, and pointing to a networked web server file (which is accessible to the service) which looks like this:

heat_template_version: 2013-05-23

resources:
  compute_instance: 
    type: "OS::Nova::Server"
    properties:
      flavor: m1.medium
      image: Ubuntu3
      name: test-wp-automated
      networks:
      - network: 8603a548-d019-4ef1-b286-2898acff7d24
      user_data_format: RAW
      user_data: |
        #cloud-config
        final_message: "The system is finally up after $UPTIME seconds"

outputs:
  compute_public_ip:
    description: Public IP...
    value: { get_attr: [compute_instance, first_address] }

Also I have tried just providing the template parameter with JSON which looks similar to below:

{  
   "stack_name":"teststack",
   "template":{  
      "heat_template_version":"2013-05-23",
      "resources":{  
         "compute_instance":{  
            "type":"OS::Nova::Server",
            "properties":{  
               "flavor":"m1.medium",
               "image":"Ubuntu8",
               "name":"testwp"
            }
         }
      }
   }
}

However also with this I get a 400 response. Any ideas reason as to why these aren't working I would appreciate very much!

Unfortunately - I can't at the moment! I don't have access to the environment and the person who does is on holiday. Is there nothing that can be gleaned from the information provided? Am I doing anything obviously wrong?

Template seems fine to me. I would suggest you try creating stack using CLI with debug option, providing exactly the same parameters. The request body in debug logs might help you debug further!

Thank you both for your help. I am now able to create VMs via the API. It turns out that I should have specified the ImageID in the Image field. I made the assumption I could use the name as that seems to work for other API calls - but that was my mistake!

@Adam: What version of heat engine did you get this error on? It looks like a bug, because as per the documentation, the image property of OS::Nova::Server resource accepts ID or name of the image.
