How can I send information about user who is trying to book tickets of Eventbrite?

I am trying to implement checkout flow with Eventbrite in my mobile app.
I already know the user's first name, last name, and email.
Is it possible to send this information to Eventbrite during checkout, so users do not have to enter them again while purchasing tickets?
We are building an app that will run on Android and iOS.
Using ReactNative / Heroku / PosgreSQL database
Thanks,

Xamarin Forms and PushSharp

I am developing a Xamarin Forms project which targets iOS and Android. Because I want to have push notifications, I came across PushSharp. In this video (around 25 - 30 min): https://www.youtube.com/watch?v=m2txoLvosVw, the developer have a iOS project and a PushSharpServer project where he sends a notification to a certain deviceToken.
In my project I have the application which talks to a database with Google App Engine. If a user registers a new post in my application and it gets registered in the database, what will be the best way to send out notifications to some users that a new post is available? Should the database send back a list of all the devicetokens that will get the notifications and then the notifications will be sent from the PushSharpServer-project in my application? Im a little confused about how this workflow should be so I was hoping someone could throw a little light on this subject :)
You can develop a PushSharp server app of whatever it is; console,windows service,desktop application..etc
There are many ways on how you want the app to send notifications,one of the basic ways is as follows:
Once a new post inserted, add a new record into a notification
table in your database
PushSharp server app must periodically
check notification table for any new records,then fetch device
tokens from your database then start sending notifications using
PushSharp library
Delete the record from notification table

QuickBlox Chat - Are messages stored?

I have a doubt about QuickBlox.
I want to use the chat functionality but I need to know if the messages exchanged between users are stored in database. because I need to retrieve them to show a list of the users I've talked to and the last message, such as facebook app in iOS and Android.
Thanks!
Here is info about chat history

Live chat on website using QuickBlox API

We want to develop website live chat widget using QuickBlox Chaa API.
1) In such widget user need not to login and just start chatting. Can we create one generic user that can be used for all chat sessions ?
2) Second requirement is store chat conversation , is there a way to store chat session there a way to get chat session text. Can we hook into it ?
Please tell us if its possible or not.
1) You have to register on quickblox.com. After that, create your project for an your application. Get tokens and keys to access your application. And you will have one primary user to work with QB and its modules.
2) You do not have to ask the user registration. Just give them names for a chat. If you want to use the source code of the widget ChattAR, just remove the registration code. Allow the user to enter a user name by which he enters.
3) Keep the message history you can in a module "Custom objects". This module is a flexible tool, you can create any number of data fields, and select one for each type of data you need.
Also, you can save any files (text etc.) in "Content" module for getting chat session text.

Posting on game activity feed

Is there any way to post on a user's activity feed for an iOS game? There seems to be no API for this but there is a permission
user_games_activity
on https://developers.facebook.com/docs/authentication/permissions/#open_graph_perms
I have noticed that there are activity feeds for Facebook games itself, but I haven't come across an activity feed regarding an iOS app.
Any help would be appreciated, thanks!
You can post user actions/achivements from iOS by taking publish_actions extended permission, but you need backend server support. You need a public url with open graph tags for each object/achievement.
Publish actions
Allows your app to publish to the Open Graph using Built-in Actions,
Achievements, Scores, or Custom Actions. Your app can also publish
other activity which is detailed in the Publishing Permissions doc.
Note: The user-prompt for this permission will be displayed in the
first screen of the Enhanced Auth Dialog and cannot be revoked as part
of the authentication flow. However, a user can later revoke this
permission in their Account Settings. If you want to be notified if
this happens, you should subscribe to the permissions object within
the Realtime API.
If you want to post achivements, here is basic info. For more info see the below link.
The Graph API for achievements allows game developers to publish user
achievements in their game to provide more meaningful and relevant
stories.
Note: This API is only available to applications categorized as
'Games'. You can categorize your app as 'Games' in the Developer app
by navigating to About > Basic Info and selecting 'Games` in the drop
down menu in the category field.
