Allow post request in Apache deployed Django 3.1

I need for my Django app to be able to receive unsolicited POST requests, without the CSRF token.
This question has been asked before here, but the answer given, implementing a class based view with functions get and post has not helped me.

This is my view class:

class WebHooks(TemplateView):

    def get(self, request):
        return HttpResponse("get")

    def post(self, request):
        return HttpResponse("post")

I also added the directive

<Location "/">
   AllowMethods GET POST OPTIONS
</Location>

to my httpd.conf for Apache and set the CSRF_USE_SESSION constant in Django’s settings.py to False.

Testing this with Postman keeps returning "get". The server access log reads POST /url HTTP/1.1" 403 3366.

How do I enable POST requests?

EDIT:

I did some local testing on the server and found that it must be Apache that’s screwing me here. Sending a post request to Django’s delevopment server returned "post" while returning "get" on the Apache server.

EDIT2:

It seems Apache redirects all traffic by default. To enable it to forward POST requests to the django app I need the mod_proxy and mod_rewrite modules according to this question.
I loaded the modules and edited my VirtualHost to look like this:

<VirtualHost *:443>
    RewriteEngine On
    RewriteRule /proxy/(.*)$ https://www.my.domain/$1 [P,L]
    ServerName my.domain
    SSLEngine on
    SSLProxyEngine on
    SSLCertificateFile "path/to/cert"
    SSLCertificateKeyFile "path/to/key"
</VirtualHost>

I am still unsure in which Directory directive to place the lines

    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted

POST requests still get turned into GET requests…

EDIT3:

After writing EDIT2 I reread my question and noticed that my problem went from django refusing a POST request to Apache turning POST requests to GET requests. I don’t know why. This is highly confusing to me.
