COA Alternative , dynamic queue changing for ROS > 6.32

Hello friends

Me and couple of MikroTik users are using some alternative scripts or using API to change dynamic queue traffic rates .
after MikroTik restrict the traffic changing on dynamic queues all this API tools was blocked .

now MikroTik just use COA for changing the dynamic Queues.
our radius server don’t support COA and can’t be changed .

is there any alternative way to do this ?
for example a simulated COA tool or an API tool that send a request to MikroTik and change traffic rate of Queue.
I can make any script or tool with any programming language but don’t find any way to do it .

Thank you .

Take a look at FreeRADIUS radclient.

example can be seen in this thread:

I have a script that changes my hotspot queues that of course now doesn’t work on 6.34.2 and need to have this functionality restored. What was the reasoning for doing away with this?
