Why not use the SDK V1, still in beta, but it's pretty good, I've been using it for a few months
https://github.com/meraki/dashboard-api-python ...currently: https://pypi.org/project/meraki/1.0.0b13/
Cut/paste from one of my scripts...
# get list of devices on network for the last 24 hours
t = 24 * 60 * 60
clients = await aiomeraki.networks.getNetworkClients(net['id'], timespan=t, perPage=1000, total_pages="all")
This will return all clients, the page handling is done for you.
