I think the best way to accomplish this is using the google-auth library for python.

$ pip install google-auth

I suggest to create a service account, give it the role IAP-secured Web App User and then download the JSON key for that service account.

Go to API's & Services > Credentials and copy the Client ID of the OAuth 2.0 client you want to use for your API.

Finally use this code snippet to make a request:

from google.oauth2 import service_account
from google.auth.transport.requests import AuthorizedSession

SERVICE_FILENAME = '/path/to/your/service_account_key.json'
API_URL = 'https://YOUR_API_URL'
AUDIENCE = 'YOUR_OAUTH_CLIENT_ID'

audience=API_URL
credentials = service_account.IDTokenCredentials.from_service_account_file(SERVICE_FILENAME, target_audience=AUDIENCE)

session = AuthorizedSession(credentials)

r = session.get(API_URL, headers={'accept': 'application/json'})

print(r.text)
