Question

def redirect_me():
    payload = {'key': 'value'}

How to put new data when redirecting?

Answer 1

It's easier to give the browser an html page
On which the js script will be executed and make a post request.

$.post('http://external.com', {'key':'value'}, function(data){
    window.location = data.redirect;
});
