Make an HTTP POST request to a WFS service?

Question

So I'm new to GIS and I'm missing some of the basic concepts in this field, what I need to do is to write a POST method to add or delete or update some map services I'm working on an ArcGIS server, I can modify the URL to use a GET method, put I have no idea how and where to write a POST method to modify the services.

The URL I keep on modifying is something like this:

https://someserver.domain.com/webserver/services/FAT_Testing/demokmz03/MapServer/WFSServer?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&typeName=Buildings&BBOX=0,0,100,100&

This works just fine, I also learned all these things from this site: https://enterprise.arcgis.com/en/server/latest/publish-services/linux/communicating-with-a-wfs-service-in-a-web-browser.htm

The first step is to find out whether the service supports POST requests by reading the GetCapabilities response.

https://someserver.domain.com/webserver/services/FAT_Testing/demokmz03/MapServer/WFSServer?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetCapabilities&

Which should give you an XML response that tells you (inter al):

<ows:Operation name="GetFeature">
    <ows:DCP>
        <ows:HTTP>
            ...
            <ows:Post xlink:href="https://someserver/some/path?"/>
        </ows:HTTP>
    </ows:DCP>
</ows:Operation>

Then you can read the appropriate WFS schema (for simple feature WFS version 1.1.0) to issue a GetFeature request like:

<?xml version="1.0" encoding="UTF-8"?>
<wfs:GetFeature xmlns:ows="http://www.opengis.net/ows"
 xmlns:xlink="http://www.w3.org/1999/xlink"

 xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">
    <wfs:Query typeName="qName">
    </wfs:Query>
    <wfs:Query typeName="qName">
    </wfs:Query>
</wfs:GetFeature>
