Google Cloud Status Check using REST API?

Question

I am looking for a REST API using which we can check the status of the Job. I am working in ServiceNow to do the Provision of the Virtual Instance using the REST API calls. I was able to create the REST calls successfully and the response received from the REST calls states that the STATUS:PENDING.

So, I want to check if the status has been changed from STATUS:PENDING to STATUS:DONE/READY. I want to check this using the REST API Call, is there any REST API call to check this.

The above link is used in google API console to do Various Operations on VM.

You can send a GET request to https://www.googleapis.com/compute/v1/projects/project/zones/zone/instances/instance .

This will return an Instance Resource , which contains a status property.

You can find more info about the CE REST API here .

You can also check out this example in Java of sending a GET request based on this page

public class ComputeExample {
  public static void main(String[] args) throws IOException, GeneralSecurityException {
    // Authentication is provided by the 'gcloud' tool when running locally
    // and by built-in service accounts when running on GAE, GCE, or GKE.
    GoogleCredential credential = GoogleCredential.getApplicationDefault();

    // The createScopedRequired method returns true when running on GAE or a local developer
    // machine. In that case, the desired scopes must be passed in manually. When the code is
    // running in GCE, GKE or a Managed VM, the scopes are pulled from the GCE metadata server.
    // For more information, see
    // https://developers.google.com/identity/protocols/application-default-credentials
    if (credential.createScopedRequired()) {
      credential =
          credential.createScoped(
              Collections.singletonList("https://www.googleapis.com/auth/cloud-platform"));
    }

    HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
    JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
    Compute computeService =
        new Compute.Builder(httpTransport, jsonFactory, credential)
            .setApplicationName("Google Cloud Platform Sample")
            .build();

    // TODO: Change placeholders below to appropriate parameter values for the 'get' method:

    // * Project ID for this request.
    String project = "";

    // * The name of the zone for this request.
    String zone = "";

    // * Name of the instance resource to return.
    String instance = "";

    Compute.Instances.Get request = computeService.instances().get(project, zone, instance);
    Instance response = request.execute();

    //I'm assuming there's a getStatus method here
    String status = response.getStatus(); 
   }
