Subscription handling complexity - google-glass

I create a google glass app with custom menu using mirror api. But when I click the menu it shows a synchronization icon over timeline item and the timeline becomes first position of my app.
But I cannot get the menu's click event from my notification servlet. And the Redirect Uri
are:
http://localhost:8080/oauth2callback
http://localhost:8080
https://mirrornotifications.appspot.com/forward?url=http://localhost:8080/notify
How can I solve it?

I think you're mixing up two different concepts here.
The Redirect URLs are used as part of the OAuth dance and are only important as part of a user for your Glassware authenticating themselves to your service.
You will, however, also need to subscribe to notifications in order to receive information about the menu commands. This isn't done through the API console but, instead, you will need to issue a subscriptions.insert command as documented at https://developers.google.com/glass/v1/reference/subscriptions/insert. Your Glassware only needs to do this once, however, although it may wish to update subscriptions.

Timeline subscriptions will not work with localhost — the callback URLs must be to a server that is publicly visible to the Mirror API servers that are pushing the notifications and must also support SSL.
So to test subscriptions in development, you have a couple options:
Deploy to a staging server
Try one of a handful of localhost proxies that are available
Use curl as described in this post to manually push the notification payload to your callback URL
I've found during my own development that #3 was the easiest, but as your application gets more complex you may want to look into the other options.

Refresh a page when something new appears in Django

I'm creating a website for a local establishment that uses Ifood. Ifood provides an API that allows you to check information, both regarding establishments and incoming orders.
The code is ready, but I can only show a new order update when manually refreshing the page. Which is a bit shippable. I thought about putting an automatic update with JavaScript at the given time, but it would be an ugly workaround.
In this case, I'm getting JSON data, but in a more general context.
How could I refresh the page as soon as new data appears?
An automatic update with Javascript might not be as dirty as you think. Even smartphone push notifications are really just occasionally polling under the hood.
If you really want to push from your server, WebSockets or server-side events are what you want. Unfortunately, it seems this kind of setup is not natively supported by Django.
Another option could be to use a paid service like Pusher.com. Such services usually let you listen for an even in JS, then call an API endpoint to trigger it from your server. This will work well on Django or any other server setup.

extra parameters added to my website after Conversion api gateway setup

new to FB pixels and aws
the idea to create conversion api gateway using aws from FB event manager created the stack, added the A record in DNS finished the rest of the setup in event manager.
i had 2 issue the first one i couldn't log to the screen where i can log into console and see the event triggered.
the second issue which most important to me is we have an extra parameter appended to our main website url if we want to go to home page we type www.xxxxx.com, when the page load the url is :
www.xxxxx.com/?_atid=9A7BYbPsbuWoKng5bQMvhCfscXiWPS
my question why this extra url added and how to get rid off?
sorry, i found out that it is a 3rd party tracking app i have installed which it inject the a script in the header of my main website so it tracks event activity, I installed to keep track events but didn't know or they don't mention in their docs it will change the url to something completely random which it could through savvy internet user away from your website.
thanks

how to create realtime notification in django without using django channels

For every action such as-
log in
sign up
password reset
Notifications should be seen to the user with a notification bell icon (just like Facebook)
where real-time notifications are shown according to each action performed.
Also, an email should be sent to that user.
Note - (YOU CAN USE ANY DJANGO LIBRARY EXCEPT DJANGO CHANNELS)
this is the question that I want to solve. please help me.
You can use the Google Firebase Cloud Messaging service. There a lot of packages that work with this service. I recommend you to use fcm-django package for simplicity.

How to add another option to the share functionality of Google Glass?

I am interested to add my service into the share functionality of the Google Glass, my flow is below:
1. Take photo / Record video
2. Share with -> My service
3. the photo or video should be uploaded to my site
Is this functionality possible? it is very similar to Facebook and G+ share options.
I will be happy to know how to do it, Thanks.
What you are looking for is what the Mirror API calls a Contact. Your Glassware can setup one or more Contacts, specifying what content type can be shared with you and/or if there are voice commands which will trigger the Contact.
You will also need to setup a Subscription which will be the public URL for an HTTPS enabled server that the Mirror API will use to send you the content that was shared with the Contact.
In general, the flow when a user first authorizes you to write to their time would be something like this:
Add a Subscription, so you can get callbacks.
Add one or more Contacts. In your example, you would want to register the Contacts to have acceptTypes of image/* and video/*, although you can also omit the acceptTypes to get everything (including text).
The callback you register with the subscription should be able to handle a JSON body, and should return HTTP code 200 as quickly as possible. A good procedure is to actually accept the body, place it on a job queue for processing later, and immediately return the 200 code. When processing the body, you may want to do something like
Confirm the userToken and verifyToken provided are valid.
Using the itemId, get the Timeline item, which will include attachment information about what was shared with you.
If the attachment is marked as isProcessingContent, then the content isn't ready for you and you should return the job to the queue and try again soon.
If isProcessingContent is false, you can use the attachment URL with the authentication token for the user to fetch the content itself.
There are a lot of details I've glossed over here. For a further overview of the flow, see https://developers.google.com/glass/develop/mirror/contacts

What Web Applications Do You Know Using Webhooks

Description of how a webhook works from http://webhooks.pbwiki.com/ -
How do they work?
By letting the user specify a URL for various events, the application will POST data to those URLs when the events occur...Among other things, you can:
create notifications to you or anybody via email, IRC, Jabber, ...
put the data in another app (real-time data synchronization)
process the data and repost it using the app's API
validate the data and potentially prevent it from being used by the app
Who is using web hooks?
DevjaVu, BitBucket, GitHub, Shopify, Versionshelf, PayPal (IPN), Jott (Links), IMified, PBwiki, Facebook (Platform, sort of), Mailhook.org, SMTP2Web, Astrotrain, Notifixious, Assembla, ZenDesk, Google Code
Do you know of any good uses of webhooks?
AlertGrid is the webhook consumer. You can configure it to accept http calls from ANY source and raise alert (email, sms, phone) to a specified person or group of people (works worldwide!) whenever the parameters in the http callback meet your criteria or when the http call was expected but it didn't occur (kind of 'heartbeat' monitoring). There is a visual editor for you to easily create rules.
Apart from notifying people by sms or email it can also notify existing applications by sending the http requests to their APIs.
It can also visualise data received in http callbacks and show the history.
Unfortunately, the wiki is not the most up to date list of known implementations. I have my own list that I'll put on the wiki when I get around to reorganizing it. Some not mentioned in the current list:
Dropbox
Gnip
Google Code (Project Hosting)
Checkout by Amazon (both for notifications and as actual callbacks with return data)
Hubilicious
Beanstalk
Google Checkout
MailChimp
SurveyGizmo
Hey!Watch
MySpace (for app developers)
I know shopify is using webhooks quite successfully now. By extension so is fetchapp uses them as well. You either are sending an xml file, or receiving one and doing your own processing logic on it.
Oh and shopify's wiki in the link has a whole write up about how to implement it in your app.
OfficeAutopilot has an interesting version of webhooks.. they use their rule interface to trigger API posts. Can trigger in response to any system event.. email opens, clicks, page visits, purchases, etc, etc.
Kiln 1.2 uses webhooks much like GitHub, BitBucket, etc.
(Disclaimer: I'm a Kiln/FogBugz dev.)
Say for example you want to get data from any API( eg. twitter, facebook etc.,). Instead of you polling the data for every few minutes/seconds, it POSTS the data to the specified URL, whenever it is available.
By using this, you will avoid unnecessary polling like say you poll and data is not there yet.
StorageRoom is a JSON-based CMS that supports webhooks, so that you can notify other services or kick of some manual processing on your own servers.
(Please note: I created the service myself)
If you want to connect one service that supports webhooks to another service's API, you can check out IronWorker's webhook support. Here's a blog post that walks through connecting github webhooks to HipChat:
http://blog.iron.io/2012/04/one-webhook-to-rule-them-all-one-url.html
There are some other examples here too, one that takes a chargify callback and posts to Campfire.
