Answer 1

without loading and redirecting page
The same thing you're doing now... Making an AJAX request. (Assuming your initial AJAX request isn't rejected by the Same Origin Policy...) Upon successfully returning from the first AJAX request, you'd make a second one to your code. Something like this:
$.ajax({
url: 'someAPI',
success: function (response) {
$.ajax({
url: 'someDBPage',
success : function (dbResponse) {
// notify the user of success
}
});
}
});
The PHP code at someDBPage would interact with your database just like any other PHP code. And you'd send it data just like any other AJAX POST request, similar to how you're sending data to the API URL now.

Answer 2

You could try:
$.get("http://someexternalwebsite.com/API/?variable="+value) for the http GET method.
or:
Use JavaScript:
function post(data, url){
$.post(url , data
, function (response) {
func(response);
});
}
Then use post(....) inside jquery
I hope it helps you, Good luck :)
