How to support my app in Citrix MDM solution

I have application on App store. I want to add support for Citrix MDM solution, which will allow end user to install application as in-office app.
Want to know what are the steps I need to perform in application?
I have gone through the details on citrix and got following information in bits and pieces and have some question on top of information
Need to use the MAM SDK in iOS app. From where I should Download the SDK? Is it freely available for POC purpose?
If I integrate the SDK what are the changes I need to do in application? any sample application available?
Need to wrap the iOS application . Is it required if I use MAM SDK?
My application communicate with my server and has user authentication. Do I need to change anything on my server?
Is dummy/temporary server setup of Citrix is available to test my application?
Let me tackle each question.
You'll want to download the MAM SDK from the citrix.com web site. To do so though you'll need to first create a user account. It is free to download.
The changes to your iOS app are fairly straightforward. I won't repeat them here, but in the MAM SDK download you'll find step-by-step instructions on what you need to do. There is a sample app with source code provided.
You no longer need to MDX Wrap your iOS application. That's the older way of getting your apps managed by Citrix Endpoint Management. The new MAM SDK approach replaces that mechanism.
There are no changes needed to your authentication.
There's no dummy server available, but you can request a trial site. Create an account at Citrix Cloud and request a trial of Endpoint Management.

Using MS graph API in production environment

I am integrating Onenote with my application. I am using MS Graph API's for getting data from Onenote. To consume the api's I am generating the token as mentioned at link get auth tokens.
I am registering my application at MS application registration portal. Do we need to purchase any kind of paid license to use services provided by MS graph API's.
The app registration process seems simple and doesn't differentiate between applications that can be used in production/test environment.

Apps registered in the app registration portal can be used for production or test environments. There isn't any switch that needs to be set when you're ready to ship. Congrats on shipping your app to production!

We don't charge for access to the API. Some of the services exposed in Graph via APIs require licenses like Intune. It sounds like you're using OneNote so as long as users of your app are already using OneNote you're fine to access their notes via our API. Just be sure not to DDOS us :)
If you can share, our community would love to hear about your app!

Integrate Amazon Payments on iOS (Swift or Objective-C)

We are making an app that can sell event tickets from an iOS app. Right now I have implemented Paypal and Stripe payments on my app to charge the customer.
I was asked to integrate Amazon payments on our "NATIVE iOS" app to charge the user of purchased event tickets. I found the integration instructions on the Amazon Payment site but it seems to be compatible for websites only. See https://payments.amazon.com/developer
This was written on their home page:
"Login and Pay with Amazon is the fast, easy and secure way to pay on desktop, tablet and mobile." - https://payments.amazon.com/home
Can you show me how to do it on Swift or Objective-C?
Note: This is about charging the client for payment of a product and not integrating the normal Amazon login or Amazon web services which I think is a different thing from "Amazon Payments" which should be similar to Stripe and Paypal.
From: https://payments.amazon.com/documentation/lpwa/201749840#201749840
Note: The Amazon Payments service has been designed and developed for use within a web browser only. Our Service cannot be used within a native application (including, without limitation, iOS, Android, RIM and Windows operating systems). Amazon Payments reserves the right to suspend the Payment Account of any user of our services that has implemented our Service within a native application.
Check out this resource I found some time back:
http://www.chupamobile.com/resources/amazon-mobile-payment
However, I am not one hundred percent sure you can actually integrate Amazon Payments into the iOS app natively, as there isn't an official SDK or API that you can use for Android or iOS. However what you could try to do is integrate their C# SDK into your project and then access it through your app.
Hope that helps.

paypal api for blackberry

I am recently developing a business application naming MyTicket.
I want that paypal gateway should be open within the app So
for that is there any paypal api in blackberry that helps me in fulfilling this
task.
I have already tried with creating a Paypal API wrapper for example using PHP, which is used by a proxy page. Then in the BlackBerry, use standard HTTP requests to send GET/POST requests to the proxy page. The proxy page will in turn use the wrapper you created to set up payment for you and your customer.But by following this way we are able to make credit card payments with the application and entire transaction will happen at the server end and in response we may obtain a result at client end that transaction is happened successfully.
But i want that the paypal transaction will happen with the paypal account.So is there any
sdk in blackberry which helps me in fulfilling this request.
Thanks And Regards
Pinkesh Gupta
There was an API, but they dropped support. I think now the only platforms supported are iOS and Android: PayPal -Mobile Payment Libraries
(If you want to check out how the BB version was like, or if you manage to find the jar, this was the development guide:MPL Guide for BlackBerry)
Now RIM has a Payment Service that might help you: Payment Service
If you use the standard Express Checkout API within your app it'll automatically utilize the mobile checkout experience.
I use this in my jQuery Mobile Apps and it works great. If you're building a native Java app, though, you might have to use some sort of an embedded web page to make it work.

How to use EndPoints to generate API library in Objective-C in Google App Engine

I used google app engine as my backend server. I watched the google I/O video, and it said it can generate the IOS api library in EndPoints by command line. But I couldn't find the way to do that, and there is no information about it on the Internet. Is there anyone who uses google app engine as their IOS app backend and could answer my question?
Working with GAE, there is no way to generate an API "in objective-c". Google app engine infrastructure supports Java and python, so you need to write your API in one of these languages to deploy it in GAE cloud.
Then, in your iOS application, you will need to communicate with the APIs you just deployed in GAE, this can be done with a so called client library. Here is an example of a client library for Objective-C.
Cloud Endpoints is still under Trusted Tester program.
You can sign up here:
http://endpoints-trusted-tester.appspot.com/
UPDATE Official docs on generating iOS client libs can be found here:
Python
Java
