How to create/delete/block freeradius users?

Question

MySQL

Good afternoon.
There is a server with Freeradius, users are in the Mysql database.
It is necessary to create users through a site that is located on another server, for example, on the wordpress engine.
How to create/delete/block freeradius users?
My solutions:
1) Open the database to the outside world and create users through sql. Confuses access to the database from outside.
2) Explore the rlm_rest module for freeradius using the brute force method, and set up the rest-api.
The enumeration method thanks to the "excellent" documentation for this module: "FIXME"
Link to of. documentation: https://networkradius.com/doc/3.0.10/raddb/mods-av... .
3) Write your script / program with api. And spin it on the server.
4) Google, Google and Google again. <--- Now I'm here.
