Try the examples above, then modify them to fit your network. Next week, I’ll cover for live graphing.
Let me know in the comments. Want the code as a ready-to-use Python script? Download the gist here.
conns = api(cmd='/ip/firewall/connection/print') tcp_count = sum(1 for c in conns if c['protocol'] == 'tcp') udp_count = sum(1 for c in conns if c['protocol'] == 'udp') mikrotik api examples
Make sure /ip service set api-ssl disabled=no is enabled on the router. RouterOS 7.14 introduced REST API, but the classic API also works fine. For large networks, try async:
print(f"Active connections: TCP={tcp_count}, UDP={udp_count}") Limit a client’s bandwidth via script. Try the examples above, then modify them to fit your network
leases = api(cmd='/ip/dhcp-server/lease/print') for lease in leases: if lease['comment'] == 'printer-api': print(f"Lease: {lease['address']} -> {lease['mac-address']}") Toggle a rule by comment (safer than index).

If you manage more than one MikroTik router, logging into WinBox or WebFig for every small change gets old fast. The MikroTik API lets you script configuration, gather data, and react to network events — all from your own code.
api(cmd='/queue/simple/add', name='client-limited', target='192.168.88.100/32', max_limit='5M/5M', comment='api-created') For production, always use SSL on port 8729.
