java – How to write springboot job to listen for a result of a search page which is PHP

Sorry guys if it is trivial, but I have no idea how to write a spring boot job that searches in a PHP web page.

So there is a PHP web page, where you can find some search field and a button which will give you the results based on the search fields.

I have always the main URL, like
Under F12 (with a browser) I can see the following:

Request URL:
Request Method: POST
Content-Type: application/x-www-form-urlencoded

and some Form Data which holds the search filters:

some_search(search_type)(living_search_type): somedummydata

And of course a lot of other data which maybe not necessary.

I know how to write REST API applications, but I have no idea how I could write some scheduled-code to listen to the results of a PHP search site.

So is it possible somehow?
