Parse.Com - HTTP method in cloud code, how do I wait for the response

Question

In my parse cloud code, the HttpRequest in beforeSave is getting executed successfully but the code blows through before I have had time to parse the response and determine whether I want to return a response.success() or a response.error().

I know I am missing something here, any input, ideas from the community here would be appreciated. Thanks

Parse.Cloud.beforeSave(Parse.User, function (request, response) {    
    var user = request.object;
    var key = user.get("recaptcha");  

        Parse.Cloud.httpRequest({
        url: 'https://www.google.com/recaptcha/api/siteverify?secret=<ITS A SECRET>&response=' + key,
        success: function (httpResponse) {
            var status = JSON.parse(httpResponse.text).success;
            console.log(status);
            if (status === false) {
                response.error();
            } else {
                response.success();
            }
        }
    });
});

Hi there, thanks for getting in touch, I am just looking to extract the status value from the json response, and if the status is true then save the data (via response.success()) into the user table else do not save the data. (response.error()) — user3524762

So you're getting the status out? Or do you need to change to ['success'] to index into the JSON object — Wain

That is correct, I am getting status from the json response, problem is that it blows through before the response has been returned from Google recaptcha. — user3524762

I mean, do you see the status printed in the log? The only other thing to do is use a promise instead of the simple callback. Are you sure the http request doesn't return an error you aren't handling? — Wain

I got it working...Parse.Cloud.httpRequest() is asynchronous, here is the solution that worked for me, hope it helps someone else.

Parse.Cloud.beforeSave(Parse.User, function (request, response) {    
    var user = request.object;
    var key = user.get("recaptcha");  
    if (!request.object.existed()) {
        return Parse.Cloud.httpRequest({
            method: 'POST',
            headers: {
                'Content-Type': 'application/json'
            },                
            url: 'https://www.google.com/recaptcha/api/siteverify?secret=<ITS A SECRET>&response=' + key,
            body: request,
            success: function(httpResponse) {
                var status = JSON.parse(httpResponse.text).success;
                if (status === false) {
                    response.error();
                } else {
                    response.success();
                }
            },
            error: function(httpResponse) {
                response.error(httpResponse);
            }  
        });
        }
       });
