How to get function activation result after migrating to an app?

Hi,

I have a function which I invoke by sending a HTTP request:

https://faas-lon1-123456.doserverless.co/api/v1/namespaces/fn-my-namespace/actions/foo/bar

This immediately returns without blocking and sends back a x-openwhisk-activation-id HTTP header. I then poll /api/v1/namespaces/fn-my-namespace/activations/{$id}/result until the result is ready. I then send a HTTP request to /api/v1/namespaces/fn-my-namespace/activations/{$id} to fetch metdata about the result (time spent and memory used).

I want to move these functions to the app platform so I can take advantage of automatic Github builds. The problem is I’m given a ondigitalocean.app subdomain which doesn’t seem to have the API endpoints I need. A request to my-application.ondigitalocean.app/foo/bar still gives me the x-openwhisk-activation-id header but I don’t know where to use the activation ID to get the result/metadata. Also with this URL the request is blocking until the function is finished and it seems wasteful to keep a HTTP connection open for up to 15 minutes.

Please let me know if what I’m trying to do is possible. It seems like it should be but I couldn’t find any documentation.

Thanks.
