Google MAP API | Push Notification for Website

I am using Google Maps API for a project whose functionality is something like below
Functionality achieved:
When user sign in they see map and their current location is traced. Users can mark their favorite location and add a comment.
Functionality required and I need help in:
When any user passes through any location in real time, then my web application should send a notification saying "you are someone's favorite place do you want to add comment and xyz..."
Can anyone help me even with a hint on how I can achieve this for the web application?
P.S: I am not using any mobile application for this purpose. This is a web application.
It sounds like you're already set up with getting the user's location through the browser geolocation api when the page loads. My suggestion is to get the user's location again on a certain interval, every couple minutes maybe. If the new location is more than a little bit different than the previous location, send an ajax request to your server, see if the new location is near one of these favorite places, and if so, display a notification that they are near this place.

Access to Mobile Contact of user through website

Is it possible to access mobile phone contacts/google contacts through a mobile/desktop website.
I am okay with the access being similar to playstore app where a user first have to allow the website to access contacts
Thanks
You can access Google's People APIs.
To easily get permission and do authentication on behalf of the user to those APIs, you can use Google Play Services GoogleAPI service, see this and this.

Sending sms from twitter to mobile number

I am building web application that will send sms to users on their mobile numbers.
I have been asked to use twitter sms service. After some googling, i come to know that i can send sms/tweet using twitter api to users that are my friend at twitter and they have set up their mobile number to receive tweets on their mobile number.
My questions is that can i send sms to any mobile number (not registered at twitter) using twitter api from my twitter account. Is there any work around?
Thanking you in advance...
We can use SMS follow, SMS follow is used to receive Twitter account updates without having to sign up or add your phone to a Twitter account.
This helped me.

How to verify the local business by phone in google map ? I didn't see any field area to put my number?

When I go to this link: https://support.google.com/business/answer/2911778, there is verification by phone option and I clicked on into your dashboard but in dashboard I could not find input field for phone number. How can I verify in this condition by phone?
I was able to reproduce this issue.
According to the Google documentation on Create and verify a local business on Google, You can only verify your business through phone if you are verifying a business that is already on Google. If you want verify a new business on Google than you have to verify it by postcard that will reach your address with which you have registered your business in 1-2 weeks.
Hope this would help!!

Is there a limit of in-app purchases in Windows Phone 8 app?

We've published WP8 app for purchasing magazines/newspapers using in-app purchases. We've created single in-app purchase for each single issue + some subscriptions and 10pack in-app purchases, together there is 134 in-app purchases defined in the WP Store for the app.
The problem is, the CurrentApp.LoadListingInformationAsync() API returns only the list of first 100 in-app purchases. Is this expected behavior that Windows Phone 8 app can use only 100 in-app purchases? I've not found any single information on MSDN about limit of in-app purchases for single WP8 app. Note we already know about the limit of 200 items in Windows 8 store.
So I've found a solution for this bug, when CurrentApp.LoadListingInformationAsync() returned only first 100 published products:
This is actually undocumented feature/bug in this method, it returns only first 100 products in case you have created more than 100 items for your app.
In order to get information about remaining products, you need to use this API:
CurrentApp.LoadListingInformationByProductIdsAsync(listOfIds). It returns info about any published product, if you know the product.Id. Thanks to this method we're able to fix our app and provide to users option to buy any published product.
I've also sent message to Microsoft support, if they can give me any clarification regarding this unexpected behavior. In the meantime I'm glad the solution with the second method works.
Here’s a link to the strategy for dealing with the in-app purchase limit:
