All the balancer manager does is create HTTP requests to the Apache web server, so you can easier use the shell and curl for example to automate a lot of stuff.
It is true that a formal API isn't documented (I should get on that... it *is* long overdue) but it is easy to determine it via looking at the balancer_handler function in https://svn.apache.org/viewvc/httpd/httpd/branches/2.4.x/modules/proxy/mod_proxy_balancer.c?view=markup or by looking at the HTML of the balancer manager page.

Changes made in balancer-manager do not require a restart to take effect. You might try Python/Beautiful Soup for programmatic access.

Greetings,
On Apache 2.4.18, Ubuntu.
I am looking for a way to access balancer manager programmatically. I
tried searching around, but could not find any officially documented API
or interfaces.
We are a small organization hosted in AWS. Sometimes we have a need to
add/remove a load balancer worker in/from traffic as per current
conditions and to save the costs. We are trying to automate these
actions to avoid mistakes and control these processes via tools/scripts.
We have scripts that can spawn or stop AWS instances and now I'm looking
for extending those scripts add/remove members as per need.
I came across few curl scripts, but wanted to check if there is any
official programmatic access to balancer manager to add a member.
Also it's not clear if I tinker with worker members using manager gui
like documented at
https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypass, do I
need to reload the server again or changes will be automatically applied.
Regards,
Niranjan
