API call for organization client blacklist

[AGoodman1]

Hello, 

I apologize if this has been addressed but I could not find the answer searching the forums. 

I'm looking for an API call to display all clients that have been blacklisted via wifi policy at the organization level, not a single site. 

Any help is greatly appreciated.

Hi ,

Not possible at the org level at the moment I'm afraid.

Thank you for the quick reply,

Is there a call where I could specify the location and or perhaps a call to see blocked clients at the template level?

This is actually a horrendous thing to have to do at the moment.  This is a script I wrote to find all whitelisted clients in an org.  You can use the same thing to search for blocked clients.

#!/usr/bin/env python3
#
# meraki-list-whitelist-clients lists all the clients that have been "whitelist"
# (now called "allow list").
#
# Installation:
# meraki-list-whitelist-clients uses dotenv to safely store your credentials.  Create a file
# called .meraki.env in your home directory.  For Linux this is typically /home/username.  For
# Windows this is typically
# c:\users\<username>.
# Into .meraki.env put this line:
# MERAKI_DASHBOARD_API_KEY=<your API key>
# If you don't have an API key yet then follow the instructions on this page:
# https://documentation.meraki.com/zGeneral_Administration/Other_Topics/The_Cisco_Meraki_Dashboard_API
#
# Prior to running this script you'll need Python 3.x installed and you'll need to run the below
# commands to install the extra components required.
# pip3 install -U meraki
# pip3 install -U python-dotenv
# pip3 install -U throttler
#
# If you are using the script on Linux I would suggest marking it executable to make running
# it simpler.
# chmod +x mfw.py
#
# Usage:
# meraki-list-whitelist-clients.py -o "Your org name"
