A Cordova Plugin for Login with Amazon. Use your Amazon account to authenticate with the app. Also supports Companion App APIs for registration of AVS devices. This plugin is a wrapper around native android and iOS libraries developed by Amazon. It is advised that you are aware that without having the Amazon Shopping App on the device, on Android, the Amazon libraries will invoke a session of the default browser. Typically this is Chrome which would be fine... however for users with other browsers, such as Firefox, this plugin would break. This is a known issue and stems from how Amazon's libraries work.

Changed the build to use dotenv and also extended the plugin to support the Alexa Voice Service Companion App APIs for device registration. Support for hosted splash screen via the new ALEXA_PRE_AUTH flag is also included.
Extra Android only helper function to check for various Amazon App presence. This is to provide support to launch the Alexa App if it is present instead of linking to the Play Store as per Amazon's UX requirements.
Updated for Android API 31+ to support android:exported="true" in AndroidManifest.xml.
iOS works but is still kind of experimental.
Updated to support 3.1.x component from the Amazon Mobile App SDK (Apr 2020). iOS now requires minimum 3.1.0 due to changes in AI to AMNLWA prefix.
- Download the Amazon Mobile App SDK and extract the files to a directory on your hard drive.
- You should see a
login-with-amazon.jarfile in the LoginWithAmazon parent directory. - Copy
login-with-amazon.jarfile toplatforms/android/libs/login-with-amazon.jarof your Cordova project. - Create configuration file for Amazon API keys
config\project.json - If you do not have your API Key yet, see Android App Signatures and API Keys and follow the instructions under "Retrieving an Android API Key".
- Set your Amazon API keys in
build.json
For example, your build.json might look like this:
"android":
{
"debug":
{
"AMAZON_API_KEY" : "hdgGHHDG......8yRM=="
},
"release":
{
"AMAZON_API_KEY" : "dh8HGuDQ......rt5H=="
}
},
By default, the value of API key from debug section will be used.
This plugin uses dotenv to determine if you are building for release or debug.
In order to use API key from release section set your environment to build release.
- If you have not installed Xcode, you can get it from Apple's Xcode.
- Download the Amazon Mobile App SDK and extract the files to a directory on your hard drive.
- You should see a LoginWithAmazon.framework directory in the LoginWithAmazon parent directory. This contains the Login with Amazon library.
- Extra Tip for developers on Windows using TACO: Because NTFS doesn't handle symlinks well, you are advised to manually recreate the folders in the archive as directories and extracting the actual files out into those folders.
- With your project open in Xcode, select the Frameworks folder, then click File from the main menu and select Add Files to "project". In the dialog, select LoginWithAmazon.framework and click Add.
- Select Build Settings. Click All to view all settings.
- Under Search Paths, ensure that the LoginWithAmazon.framework directory is in the Framework Search Paths. For example:
- In the main menu, click Product and select Build. The build should complete successfully.
- Add a URL Scheme to Your App Property List
- Get Amazon API key for your iOS app. There is only one key for iOS.

}
window.AmazonLoginPlugin.authorize(Object options, Function success, Function failure)
Success function returns an object like:
{
accessToken: "...",
user:
{
name: "Full Name",
email: "email@example.com",
user_id: "63456543...",
postal_code: "123..."
}
}
Some of these fields may not appear depending on the scope of the profile requested.
Failure function returns an error String.
Retrieve previously auth'ed profile information.
window.AmazonLoginPlugin.fetchUserProfile(Function success, Function failure)

window.AmazonLoginPlugin.signOut(Function success, Function failure)
Android devices without the Amazon Shopping App will leave a session of the Chrome browser still lingering and it would be advised to manage that if you are concerned about user security.
Invoke with the following options:
var ALEXA_PRE_AUTH = 0x00001;
var options = {
scopeFlag: ALEXA_PRE_AUTH,
productID: "MyDeviceModel",
productDSN: "SerialNum232...",
codeChallenge: "2B34E2F342..."
}
window.AmazonLoginPlugin.authorizeDevice(Object options, Function success, Function failure)

Helper function to check if such an Amazon App exists on the phone and launch it if found.
| Type of Amazon App | Enum |
|---|---|
| None | 0x00000 |
| Amazon Shopping App | 0x00001 |
| Amazon Alexa App | 0x00010 |
Please only detect for one app at a time.

var APPS_SHOPPING = 0x00001;
var options = {
appsFlag: APPS_SHOPPING,
appLaunch: true
}
The appLaunch flag set to true will launch the Amazon app if found and do nothing if set to false.
The className of the Amazon app would be returned regardless on if appLaunch was set true or false if the requested app was found.
If the app was not detected a null object would be returned.
window.AmazonLoginPlugin.appExists(Object options, Function success, Function failure)
On Android, success function returns an object like:
{
appName: "com.amazon..."
}
Failure function returns an error String.
On iOS, it returns YES or NO depending if it was able to locate the app.
For those who are using VisualStudio 2017 TACO (still?!) and building on a remote Mac with their Amazon libraries on their Windows computers, you might like to add the following script and Cordova hook to help build the necessary bits. Below is an updated script that may help you out...
In your config.xml add a reference to the before-build script:
<platform name="ios">
<hook src="path/to/script/below/before-build.js" type="before_build" />
...
</platform>
And the before-build.js script for your before-build hook above:
const fs = require('fs-extra');
const path = require('path');
module.exports = function (context) {
var copyBridgeHeaderId = 0;
var copyBridgeHeaderLock = 0;
var copyBridgeHeaderSource;
var copyBridgeHeaderTarget;
const copyBridgeHeaderFn = function () {
process.stdout.write('.');
if (!copyBridgeHeaderLock) {
fs.open(copyBridgeHeaderTarget, 'w+', function (err, fd) {
if (err) { // && err.code === 'EBUSY'
//do nothing till next loop
process.stdout.write(err.code);
} else {
process.stdout.write('!');
fs.closeSync(fd);
process.stdout.write('.:.');
if (!copyBridgeHeaderLock) {
process.stdout.write('.,.');
copyBridgeHeaderLock = 1;
process.stdout.write('.*.');
fs.copy(copyBridgeHeaderSource, copyBridgeHeaderTarget, function (err) {
if (err) {
process.stdout.write('.err.');
copyBridgeHeaderLock = 0;
//return console.error(err);
} else {
process.stdout.write('.bridging-header.h copy completed. ');
clearInterval(copyBridgeHeaderId);
copyBridgeHeaderId = 0;
copyBridgeHeaderLock = 0;
}
});
}
}
});
}
};
// Ensure we are in an iOS build
if (context.opts.cordova.platforms.indexOf('ios') !== -1) {
var cordovaUtil = context.requireCordovaModule('cordova-lib/src/cordova/util');
var ConfigParser;
try {
console.log('before-build: trying to set config parser');
ConfigParser = context.requireCordovaModule('cordova-lib/src/ConfigParser/ConfigParser');
} catch (ex) {
console.log('before-build: failed to set so using alternate');
ConfigParser = context.requireCordovaModule('cordova-common/src/ConfigParser/ConfigParser');
}
var projectRoot = cordovaUtil.isCordova();
var xml = cordovaUtil.projectConfig(projectRoot);
var cfg = new ConfigParser(xml);
var appName = cfg.name();
// Customize with the location of your LoginWithAmazon.framework path here:
var pluginPath = 'plugins/cordova-plugin-amazon-login/libs/LoginWithAmazon.framework';
// The location of where Xcode wants to have (capital P for Plugins) the LoginWithAmazon.framework:
var iosPath = path.join('platforms/ios/', appName, '/Plugins/cordova-plugin-amazon-login/LoginWithAmazon.framework');
// copy source folder to where Xcode wants the framework to be
fs.copy(pluginPath, iosPath, function (err) {
if (err) {
console.log('before-build: error occured while copying the framework.');
return console.error(err);
}
console.log('before-build: LoginWithAmazon.framework copy completed!');
});
}
};
