Hi KH,
 
From postman it works fine, we are using a python script which uses async api calls, pasting the code snippet here:
async def main_async(api_key, ORG_ID, operations, tag😞
    global DEVICES, NETWORKS, TEMPLATES
    async with meraki.aio.AsyncDashboardAPI(api_key, maximum_concurrent_requests=1, maximum_retries=4,
                                            print_console=True, suppress_logging=False) as dashboard:
        # Backup org
        await asyncio.gather(backup_org(dashboard, ORG_ID, operations), backup_devices(dashboard, ORG_ID, operations, DEVICES), backup_networks(dashboard, ORG_ID, operations, NETWORKS + TEMPLATES), backup_mr_ssids(dashboard, operations, ORG_ID, NETWORKS + TEMPLATES))
