Bitcoin is a cryptocurrency and a digital payment system with 5.8 million users. In this blog post, you will learn how easy it is to build an Appery.io hybrid app to accept payments in bitcoins. It just takes a few simple steps to build the app and ready the payment ecosystem.

First, you need to get a merchant sandbox account on the BitPay server at https://test.bitpay.com/get-started. There are other payment servers, but BitPay currently is the largest and oldest bitcoin payment processor in the world, serving industry-leading merchants on six continents.

Next. You need to import a plug-in that will be the prebuilt (mostly prebuilt) client app. To do this, when the App Builder loads, choose the creation From Plugin option and check the BitPay App plug-in. (Learn more details about how to build an Ionic app in Appery.io.)

Then, you need to add one more piece to Appery.io, the BitPay Cordova plug-in. Go to https://github.com/bitpay/cordova-sdk and save this repository as a ZIP file. Upload this file to Appery.io to install this plug-in. (Please read this for more information about installing Cordova plug-ins into Appery.io.)

Next, Generate a BitPay API token with point-of-sale capability without client authentication at https://test.bitpay.com/api-tokens. With this done, get back to your app to set the token value. At this point, a distribution certificate should be associated with your app as described in https://docs.appery.io/docs/appexport-certificate-management.

Finally, as a customer making purchases with BitPay App, you need a bitcoin wallet installed on your phone. A bitcoin wallet is an app that lets you receive, hold, and spend bitcoins. This list shows bitcoin wallets supported by BitPay.

And, one more thing. After all of this is done, please make sure you switch to a merchant production account on the BitPay server at https://bitpay.com/get-started.

That’s all.  Now your app is ready to take bitcoin payments.

EveryoneAPI by Telo allows to convert a phone number into real business intelligence with a simple API request. The complete reverse phone append product is simple to use, yet powerful and built for developers by developers. As you probably already know, integrating with any 3rd party REST API using the Appery.io Server Code is also simple. In this blog post, I will show you how to invoke a test a script that calls the Everyone API.

To start, create a new Server Code script with the following code:

var telephone = request.get("telephone");
var url = "https://api.everyoneapi.com/v1/phone/"+telephone;
var auth_token = "AU83e975.....";
var account_sid = "AC659275.....";

var XHRResponse = XHR2.send("GET", url, {
"parameters": {
"auth_token": auth_token,
"account_sid": account_sid,
"pretty": "true"
}
});
Apperyio.response.success(XHRResponse.body, "application/json");

The only thing you need to do, is to replace the auth_token and account_sid with values from your account. Sign up for an account here. It’s fast and simple.

The phone number for which you want to get information is passed as a parameter to the script (line 1). To test the script, switch to Script parameter tab (on the right side), enter a parameter called telephone and then set it to a test value. Here is an example testing the API using the Appery.io telephone number:

Server Code script

Once you finished and tested the script, you easily import into your app. This video shows how to do that.

Looking for more APIs by Telo? Check out the CallerID Server Code plug-in:

Plug-ins

This plug-in creates a Server Code script that integrates with OpenCNAM API. The OpenCNAM API allows you to get caller ID information for phone number provided.

Geolocation is one of the most widely used APIs in mobile apps today. From weather to Uber and Lyft, the device location is crucial information and many APIs use it to determine what services and products are available in a given location. When building a mobile app in Appery.io, using the Geolocation API is simple. Apache Cordova library is built-in in every new Appery.io app. Invoking Geolocation will return the latitude, longitude (and other) information which can then be passed to any REST API. The following two short videos show how to use and invoke Geolocation in an Ionic and jQuery Mobile apps:

• A Quick Guide to Using Geolocation API (Ionic App) 
• A Quick Guide to Using Geolocation API (jQuery Mobile App)

The Appery.io Database provides storage for your mobile app data. You can store data such as users, orders, purchases, products or anything else. The Appery.io Database is a cloud NoSQL database and provides a very simple and elegant REST API to work with the database.

One of the most common cases for an enterprise mobile app is to create/save a new item/record and then redisplay the list in the app with the newly created item.

Accessing the database directly from the client is fine but requires two requests to the database.

1. A request to save the new item/record into the database.
2. Once the 1st request completes, on its success, a request to get the updated list to display in the app.

A better approach is to do both the create and list in a single request from the app. This is very simple to do from Appery.io Server Code script. The following script shows how to create a new record and then get the updated list:

var dbId = "cdaec951....d8";
var collectionName = "People"
 
var newName = request.get("name");
var newTitle = request.get("title");
 
// Save new object into the collection
Collection.createObject(dbId, collectionName, {
   "name": newName,
   "title": newTitle
});
 
// Retrieve updated data from the collection
var result = Collection.query(dbId, collectionName);
// Return the updated list (including the new object)
Apperyio.response.success(result, "application/json");

In this simple script you first create a new Person object (line 8) and then do another query to get the updated list of people (line 14). The script response returns the updated list of people. This script automatically has a REST API which is the invoked from the app.

What’s most important, there is only a single request from the app to the Server Code script. A single request is usually better than two requests. Also, you can add additional logic to the script without impacting the app. For example, you can send an email when a new person is added. Or, you can send  Push Notification when a new person is added. All this can be done without impacting the app. That’s nice.

Appery.io API Express make it fast and simple to connect to an enterprise data source and expose it via a REST API. With API Express you can quickly create an API for:

• A relational database
• A WSDL service (SOAP)
• An existing REST API

In this tutorial, I’m going to show how to expose an existing WSDL service as a REST API and then build a mobile app using the API.

Testing your mobile app is hard. You need to test the app UI (client) and app backend.

The Appery.io Services team has built hundreds of apps for our clients and to help testing the app backed has come up with a powerful testing approach and tool.

In this blog post you will learn about this approach.

The services team has successfully developed and used a tool to streamline unit testing of hybrid mobile apps that are hooked up with Appery.io Server Code scripts. Server Code allows to develop custom server-side business logic (using JavaScript) without the need to build or maintain server infrastructure.

It is common for a Server Code script to access and query the Appery.io Database. This tool gives the benefits of testing such scripts without impacting the database. On top of that, supporting data driven testing by this tool empowers streamlining resources for regression checking. In addition, the time-consuming database “dropping and recreating” is a thing of the past.

The tool has a GUI and a set of shell scripts integrated with the Appery.io platform via REST API services.

GUI for testing Server Code scripts

The testing preparation is as easy as preparing valid input parameters and verifiable output results.

Once everything is configured, testing is started by clicking the Run button and can be completed as many times as necessary.

Since all the communication is done using JSON format, updating input parameters and reviewing outputs can be easily done with a built-in text editor.

Using this tool testing is done twice as fast.

Right now this tool is used by the Appery.io Services team. If you would like to use it for testing with your Appery.io app or learn more, please email us.

Dyjit’s vision is to make life better by introducing digital experiences where they do not yet exist. Dyjit’s first product, knowye (know what you eat), is a hospitality platform that transforms the traditional paper menu into a digital marketing channel and enables restaurants to cater and market to shifting consumer needs.

• Filter the menu to items that meet your preferences. For example, if you are a vegan or looking for a gluten-free dish, your personal menu with additional ingredient related details will be shown.
• Select items for your order.
• Estimate your bill, calculate the tip, split with your group.
• Add items to your wishlist or favorites.
• Keep your menu and selection history.

The Dyjit team selected the Appery.io lowcode platform to build and launch their first mobile app.

The Appery.io visual App Builder allows building the app UI 3-4 times faster than using traditional tools.

The Appery.io platform also provides out-of-the-box, integrated backend services such as a cloud database, Server Code for app logic and Push Notifications. This means you don’t need to look for any other backend services and can build and test the entire app quickly and with less resources. The platform enables building a complete mobile app fast, without needing to have a traditional development team.

The app UI was quickly built using the Appery.io App Builder for jQuery Mobile. On the backend, the app leverages the Appery.io Database and Server Code for custom app logic. Running the app on the Appery.io platform will enable the Dyjit team to easily scale the app to any number of backend API calls without lifting a finger. And that’s precisely the reason why the Dyjit team selected the Appery.io platform – it enables them to spend time building their product without worrying about app infrastructure and tooling.

Knowye is available in the Apple and Android app stores and piloting at Heartland Brewery in New York’s Port Authority. Follow knowye’s progress on their Facebook page.

Bon appetite!

Appery.io had a strong 2016 and inches closer and closer to 400,000 developers. At the same time, the constant platform updates we roll out add more benefits, services, features, and options. Even without the constant updates, supporting a platform with so many developers would not be a simple task. Our platform has to be ready for continuous updates, increased load, and new user requests and requirements.

We want to provide high SLA level services and avoid unexpected slowdowns and downtimes for customers’ apps even during peak hours. To provide the required scalability and resilience, we rely on industry leader Amazon Web Services and its various features such as Auto Scaling, Launch Configurations, and CloudWatch.

In this blog post you will learn how exactly we ensure scalability and resilience for Appery.io API Express and Server Code services.
