How can I send email notifications with Parse and Mandrill?

I am trying to use Mandrill to send an event-based email notification to the users of my web app. I am using Parse with Back4App.
In this tutorial (https://docs.back4app.com/docs/integrations/parse-server-mandrill/), the hosting providers suggest using the following method to call the Mandrill cloud code from an Android application:
public class Mandrill extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
Parse.initialize(new Parse.Configuration.Builder(this)
.applicationId("your back4app app id”)
.clientKey(“your back4app client key ")
.server("https://parseapi.back4app.com/").build()
);
Map < String, String > params = new HashMap < > ();
params.put("text", "Sample mail body");
params.put("subject", "Test Parse Push");
params.put("fromEmail", "someone#example.com");
params.put("fromName", "Source User");
params.put("toEmail", "other#example.com");
params.put("toName", "Target user");
params.put("replyTo", "reply-to#example.com");
ParseCloud.callFunctionInBackground("sendMail", params, new FunctionCallback < Object > () {
#Override
public void done(Object response, ParseException exc) {
Log.e("cloud code example", "response: " + response);
}
});
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mandrill);
}
}
How can I implement this in JavaScript with the Parse JavaScript SDK?
This is what I've done so far but it won't send an email. I have Mandrill set up, as well as a verified email domain and valid DKIM and SPF.
// Run email Cloud code
Parse.Cloud.run("sendMail", {
text: "Email Test",
subject: "Email Test",
fromEmail: "no-reply#test.ca",
fromName: "TEST",
toEmail: "test#gmail.com",
toName: "test",
replyTo: "no-reply#test.ca"
}).then(function(result) {
// make sure to set the email sent flag on the object
console.log("result :" + JSON.stringify(result));
}, function(error) {
// error
});
I don't even get a result in the console, so I figure the cloud code is not even executing.

You have to add the Mandrill Email Adapter to the initialisation of your Parse Server, as described on their Github page. Also check the Parse Server Guide for how to initialise or use their example project.
Then set up Cloud Code by following the guide. You'll want to either call a Cloud Code function using your Android app or from any Javascript app, or use beforeSave or afterSave hooks of a Parse Object directly in Cloud Code, which allow you to send Welcome Emails when a user signs up. That could come in handy if you want to implement behaviour based emails based on object updates. Plus, because it is on the server and not the client, it is easier to maintain and scale.
To make the Cloud Code function actually send an email via Mandrill, you need to add some more code to your Cloud Code function. First, add a file with these contents:
var _apiUrl = 'mandrillapp.com/api/1.0';
var _apiKey = process.env.MANDRILL_API_KEY || '';
exports.initialize = function(apiKey) {
_apiKey = apiKey;
};
exports.sendTemplate = function(request, response) {
request.key = _apiKey;
return Parse.Cloud.httpRequest({
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
url: 'https://' + _apiUrl + '/messages/send-template.json',
body: request,
success: function(httpResponse) {
if (response) {
response.success(httpResponse);
}
return Parse.Promise.resolve(httpResponse);
},
error: function(httpResponse) {
if (response) {
response.error(httpResponse);
}
return Parse.Promise.reject(httpResponse);
}
});
};
Require that file in your Cloud Code file, and use it like any other Promise.
var Mandrill = require("./file");
Mandrill.sendTemplate({
template_name: "TEMPLATE_NAME",
template_content: [{}],
key: process.env.MANDRILL_API_KEY,
message: {
global_merge_vars: [{
name: "REPLACABLE_CONTENT_NAME",
content: "YOUR_CONTENT",
}],
subject: "SUBJECT",
from_email: "YOUR#EMAIL.COM",
from_name: "YOUR NAME",
to: [{
email: "RECIPIENT#EMAIL.COM",
name: "RECIPIENT NAME"
}],
important: true
},
async: false
})
.then(
function success() {
})
.catch(
function error(error) {
});
Make sure you create a template on Mailchimp, right click it and choose "Send to Mandrill", so that you can use that template's name when sending via the API.
It's a bit involved, but once set up, it works like a charm. Good luck!

How do I make mail contact form in Firebase hosting?

I'm trying to migrate my website to Firebase hosting, but I have a contact form PHP mail that I want to use in Firebase too. Can I do It? And How?
Thanks!

You can create form and then submit the user data to Firebase Database and view it from your Admin Dashboard.
You can do something like this:
//Handling Contact Form
document.getElementById('submit').addEventListener('click', event => {
const leadName = document.getElementById('client_name').value;
const leadEmail = document.getElementById('client_email').value;
const leadMobile = document.getElementById('client_mobile').value;
const leadMessage = document.getElementById('client_message').value;
if(leadMobile != "" && leadEmail != "" && leadName != "") {
const leadTimestamp = Math.floor(Date.now() / 1000);
firebase.database().ref('leads').once('value', snapshot => {
var totalLeads = snapshot.numChildren();
totalLeads++;
firebase.database().ref('leads').child(totalLeads).set({
name: leadName,
mobile: leadMobile,
email: leadEmail,
message: leadMessage,
timestamp: leadTimestamp
});
$('.contact-form').hide();
$('.message-sent-success').show();
}, function(error) {
console.log(error);
});
} else {
alert('Please fill all the fields.');
}
});
The above code takes 4 user values, generates timestamp and inserts the data in Firebase Database and if you have an admin dashboard, you can use it to view it and perform further actions on it from there.
Here's how you can send email using emailjs.com
emailjs.send("gmail", "<template_name>", { //template_name is set via emailjs.com dashboard
content: email_description // you can store user data in any such variable
}).then(
function(response) {
document.write("Email sent successfully!");
},
function(error) {
document.write("Failed to send email.");
console.log(error);
}
);

Firebase hosting only serves static content, this means you can't use PHP or any server-side language there.
On the other hand, you can still use Firebase functions to send an email using an HTTP trigger via AJAX with Javascript.
This way, you can make a fully functional contact form without using server-side languages in your site.

How to prevent current user get notified?

I'm making an app that allows user to like and comment on other user post. I'm using Parse as my backend. I'm able to notified user everytime their post liked or commented. However if current user like or comment on their own post this current user still notified. How can I prevent this?
Here is the js code that I use:
Parse.Cloud.afterSave('Likes', function(request) {
// read pointer async
request.object.get("likedPost").fetch().then(function(like){
// 'post' is the commentedPost object here
var liker = like.get('createdBy');
// proceed with the rest of your code - unchanged
var query = new Parse.Query(Parse.Installation);
query.equalTo('jooveUser', liker);
Parse.Push.send({
where: query, // Set our Installation query.
data: {
alert: message = request.user.get('username') + ' liked your post',
badge: "Increment",
sound: "facebook_pop.mp3",
t : "l",
lid : request.object.id,
pid: request.object.get('likedPostId'),
lu : request.user.get('username'),
ca : request.object.createdAt,
pf : request.user.get('profilePicture')
}
}, {
success: function() {
console.log("push sent")
},
error: function(err) {
console.log("push not sent");
}
});
});
});

If I understand the context of where this code is correctly,
I recommend checking
if request.user.get("username") != Parse.CurrentUser.get("username")
Before sending out the push notification

Where is your cloud function being called from? If you're calling it from your ios code, then before you call the cloud code function, just prelude it with something like this:
if (PFUser.currentUser?.valueForKey("userName") as! String) != (parseUser.valueForKey("userName") as! String)

Facebook connect: can retrieve the id, the username but cannot retrieve the email

I can get the id and username from facebook connect, but I cannot retrieve the email !
Here is the JS script:
function connectionFacebook()
{ console.log('connectionFacebook called');
FB.api('/me?fields=email,name', { fields: 'name, email' }, function(response)
{
console.log(response);
response gives me:
Object {name: "John Doe ", id: "11112222333344445555"}
But no email !
PS. I guess it uses some old FB connect js since I work on an quite old site.
I have no idea what version of FB it uses, but I guess an old one !
ex: of code found in site;
FB.Event.subscribe('auth.login', function(response)
{
connectionFacebook();
;
});
FB.getLoginStatus(function(response)
{
if (response.authResponse)
{
connectionFacebook();
}
else
{
// no user session available, someone you dont know
//alert("getLoginStatus:deconnecté");
}
});
$.fn.connexionFacebook = function( ) {
return this.each(function () {
FB.init({
appId : xxxxxxxxx,
status : true,
cookie : true,
xfbml : true
});
});
}
})( jQuery );
<script src="http://connect.facebook.net/fr_FR/all.js"></script>
<fb:login-button show-faces="false" width="450" perms="email,user_birthday,user_location" size="medium">FaceBook connect</fb:login-button>

I'd guess that you don't have a permission to access the user's email. Facebook requires you to set the scope that determines which information you need to access.
In you case you need to specify the scope as public_profile,email to access the email. you can do that when your user logs in. Either with the API call:
FB.login(callback, { 'scope': 'public_profile,email' });
or with the button:
<fb:login-button scope="public_profile,email"></fb:login-button>
Specifying the email in the scope will ask the user to share her email address with your application when she logs in:

Using Facebook request dialog with Meteor

I'm trying to send an "app" invite to user friends using the Facebook JavaScript SDK.
Here is a template event when click the Facebook button:
"click #fb": function (e, tmp) {
Meteor.loginWithFacebook({
requestPermissions: ['user_likes',
'friends_about_me',
'user_birthday',
'email',
'user_location',
'user_work_history',
'read_friendlists',
'friends_groups',
'user_groups']
}, function (err) {
if (err) {
console.log("error when login with facebook " + err);
} else {
FB.api('/' + Meteor.user().services.facebook.id + '/friends', { fields: 'name,picture' }, function (response) {
if (response && response.data) {
friends = response.data;
friends_dep.changed();
}
});
}
});
}
after that i want the user to invite people to my app, my code looks like this (another template event):
FB.ui({method: 'apprequests',
message: 'My Great Request'
}, function(response) {
if (response && response.post_id) {
alert('Post was published.');
} else {
alert('Post was not published.');
}
}
);
And it's working. There is a Facebook dialog with all the user friends, but when trying to send the message, I get the response error = 'Post was not published.'
What am I doing wrong here?
Basically the user can build a group - and I want the user to be able to invite his facebook friends into that group. Is there anyway that when sending the request the reciver will just press "yes" and will be automatically added to the sender group?
note I'm using my local machine aka localhost:3000

Can you try removing the && response.post_id portion from the if statement?
According to the Facebook API docs for the Requests Dialog: https://developers.facebook.com/docs/reference/dialogs/requests/ the response will just have 'request' and 'to' data. It looks like you've copy and pasted your callback from an example they give for the Posts Dialog. If you still get an error after removing this then you aren't getting a response, I am unsure how the JS SDK handles responses. If you can get other API calls to work using js sdk then I'm really not sure.
I recently worked with the Facebook API and opted not to use the JS SDK because it seemed to be at odds with using the accounts-facebook package. I'm curious if you're using that too.
Some Facebook API calls like creating a Post (and possibly this one) do require a dialog box, I'll outline how I got around this without using the JS SDK in case it helps you or anyone else. I would just form the URL client side and open a popup window e.g. here's how I handled sending a post:
'click .send-message': function() {
var recipient = this.facebook_id;
var config = Accounts.loginServiceConfiguration.findOne({service: 'facebook'});
var url = "http://www.facebook.com/dialog/feed?app_id=" + config.appId +
"&display=popup&to=" + recipient + "&redirect_uri=" + Meteor.absoluteUrl('_fb?close');
window.open(url, "Create Post", "height=240,width=450,left=100,top=100");
}
Then to get the response server side:
WebApp.connectHandlers
.use(connect.query())
.use(function(req, res, next) {
if(typeof(Fiber)=="undefined") Fiber = Npm.require('fibers');
Fiber(function() {
try {
var barePath = req.url.substring(0, req.url.indexOf('?'));
var splitPath = barePath.split('/');
if (splitPath[1] !== '_fb') {
return next();
}
if (req.query.post_id) {
//process it here
}
res.writeHead(200, {'Content-Type': 'text/html'});
var content = '<html><head><script>window.close()</script></head></html>';
res.end(content, 'utf-8');
} catch (err) {
}
}).run();
});
This code is very similar to the code used in the oauth packages when opening the login popup and listening out for responses.
