Is it possible to do a POST call using a standard API in a custom logic?

Hi Experts,

I have a custom logic I'm testing where I do a GET oData request in the code using a standard class similar to this:

* Fetch X CSRF TOKEN
    DATA(request) = cl_ble_http_request=>create( ).
    request->set_header_parameter( exporting name = 'X-CSRF-TOKEN' value = 'FETCH' ).
    request->set_method( 'GET' )->set_resource_extension( lv_costrev_api ).
    TRY .
        DATA(response1) = lo_client->send( request ).
        DATA(lv_csrf) = response1->get_header_parameter( 'x-csrf-token' ).
        CATCH cx_ble_http_exception INTO DATA(l5).
    ENDTRY. 

The GET Request worked fine - however, when I try to a POST, the page is loading until I exit the page.

My question remains, is doing a POST using the lo_client->send( request ) meant to work? If so, why is it loading indefinitely?

Thanks.
