Change Dyno types through the Heroku API

I have an app running in Heroku; I'm using the Heroku scheduler to run a python script that scales the number of dynos at particular times of the day, using the python API (following this answer):

import heroku
cloud = heroku.from_key(os.environ.get('HEROKU_API_KEY'))
app = cloud.apps['myapp']
webproc = app.processes['web']
webproc.scale(1)

My question is: is there an API call to change Dyno types? For instance to change it from "standard 1X" to "standard 2X" or to "hobby".

Thanks

Not via the Python API (which is deprecated), but via the regular HTTP API you can do:

requests.patch(
    f"https://api.heroku.com/apps/{APP_ID_OR_NAME}/formation",
    json={"updates": [{"size": DYNO_TYPE, "type": "web"}]},
    headers={
        "Content-Type": "application/json",
        "Accept": "application/vnd.heroku+json; version=3",
        "Authorization": f"Bearer {TOKEN}",
    },
)

Here using the requests-library.

I believe the dyno size update applies to all process types -- here I've only list web -- at least when going from e.g. "free" to "hobby". Otherwise, you simply add those other process types to the updates-list.

See Heroku API docs: https://devcenter.heroku.com/articles/platform-api-reference#formation-batch-update

A chat with the Heroku support has confirmed that the python API has no command to perform this operation; I have therefore resorted to add the following script to the app (following this answer):

#!/bin/bash

curl -s https://s3.amazonaws.com/assets.heroku.com/heroku-client/heroku-client.tgz | tar xz
mv heroku-client/* .
rmdir heroku-client
PATH="bin:$PATH"

heroku dyno:type hobby --app MYAPP

Changing hobby with standard-1x or standard-2x as needed.
