how to use back4app to send email with mailgun

[androm...@gmail.com]

Hi i fail to use back4app with mailgun. so i just uploaded the cloud code

Parse.Cloud.define("sendEmail", function(request,response){
        var api = "apikey";
        var domain = "mydoamin";
        var mailgun = require('mailgun-js')({
        apiKey: api, 
        domain: domain
    });
    
    var mail = {
        from: "nor...@email.com",
        to: "so...@email.com",
        subject: "title",
        text: "message"
    };

    mailgun.messages().send(mail, function (error, body) {
        if (error) {
            inspect(error, 'mailgun sendError');
        } else {
            inspect(body, 'Successfully send email to "' + toEmail + '"');
        }
    });

});

I am using javascript sdk at client side

        Parse.initialize("appid", "key");

Parse.serverURL = 'what should i put for this?'

var SendEmail= Parse.Object.extend("SendEmail");

var sendEmail= new SendEmail();

$("#form").on("submit", function(e) {

e.preventDefault();

var data ={};

data.name = $("#name").val();

data.email = $("#email").val();

data.message = $("#message").val();

emailObjectCapture.set("name", data.name);

emailObjectCapture.set("email", data.email);

emailObjectCapture.set("message", data.message);
   

                         app.post('/sendEmail', function (req, res) {

Parse.Cloud.run('sendEmail', req.body).then(

function () {

console.log('Cloud Code Function called');

return res.send(200);

},

function (error) {

console.log("CLoud Code Function Called Fail");

return res.status(400).send(error.message);

});

});

This is not working and I got "app is not defined" error on client side. Am i right placing /sendEmail after app.post? 

Can't i just run Parse.Cloud.run without app.post?

i am using webhosting nodejs web app using cloud code example, since you guys don't have any vanilla javascript sample.

I am quite confuse because i never use app.post for parse, I just use Parse.Cloud.run

and do i need to use javascriptKey? or masterKey:true?

I am new to javascript and parse. Can you point me to right direction?

Hello,

Add this in Parse.serverURL = 'https://parseapi.back4app.com';

Also, you can use Parse.Cloud.Run if you are calling a function defined on your cloud code. Please check our Cloud Code Documentation http://docs.back4app.com/docs/integrations/

Best!
