General information about API

All functions take single argument, object with properties recognized by each individual API point entry. Those functions will throw error when one or more of required parameters are missing. All result will be delivered asynchronously, by executing callback functions passed as arguments to API calls.

Arguments to all API calls can have ios: {...} or android: {...} sections, values specified that way would overwrite general data from adequate platform section.

Application life cycle

Before any other operation can be performed, Boxcar API must be initialized, this is performed by calling Boxcar.init().

After that application can register retrieve list of tags by using Boxcar.getTags() or skip that step if interesting tags are already known.

To make device receive push notifications Boxcar.registerDevice() must be called, after that all new notifications are delivered to applications by executing onalert callback provided in that API call.

Starting new project using API

Make sure that on machine where build will be performed [Apache Cordova][http://cordova.apache.org/], and Android or/and IOS SDK installed.

As first step, we need to create new cordova project using:

cordova create /path/to/our-project our.domain.testapp1 "Test Application"

After that we need to switch to app directory:

cd /path/to/our-project

Next, we need to declare for what platforms we want build our application:

cordova platform add android
cordova platform add ios

Then we need to download plugin containing Boxcar SDK and it's dependencies

cordova plugin add https://github.com/boxcar/boxcar-cordova-plugin

Packages for iOS platform can be only build with Xcode IDE, executing:

cordova prepare ios

will fill platform/ios directory which can be opened in Xcode.

To build on Android you need to get google-service.json file for your project from Firebase Console, place it root directory of your cordova project and add folowing lines to config.xml of your Cordova project:

Developing for Android can also be done using IDE environment, first by preparing build directory:

cordova prepare android

and then creating IDE project from platfrom/android directory, but this can also be performed from CLI by executing

cordova build android

to build APK file, and calling

cordova run android

to install and start application on Android device.

This function is called with single object argument with properties initialized from notification content
• tags - List of strings with tags used to filter which notifications should be delivered
• udid - Unique identifier of device where application is run
