For a rust version of this library check out rs-gpapi.

SYNOPSIS

Call Google Play APIs from Node. You might want to check out the CLI package as well.

By default behaves like a Nexus device with SDK 23 for app downloads.

USAGE

var api = require('gpapi').GooglePlayAPI({
  username: user,
  password: pass,
  androidId: android_id
  // apiUserAgent: optional API agent override (see below)
  // downloadUserAgent: optional download agent override (see below)
});

// usage via Promise
api.details("com.viber.voip").then(console.log);

// usage via node callback convention
api.details("com.viber.voip", function (err, res) {
  console.log(err ? err : res);
});

Options

The options accepted:

{
  username: username,
  password: password,
  androidId: androidId,
  countryCode: 'us',
  language: 'en_US',
  requestsDefaultParams: requestsDefaultParams,
  apiUserAgent: USER_AGENT,
  downloadUserAgent: DOWNLOAD_MANAGER_USER_AGENT,
  useCache:true,
  debug: false
}

Defaults

The default apiUserAgent and downloadUserAgent is from Nexus 5X device, w/ Play Store version 6.8.44:

e.g.,:

const USER_AGENT = (
    'Android-Finsky/6.8.44.F-all%20%5B0%5D%203087104 ' +
    '(api=3,versionCode=80684400,sdk=23,device=bullhead,'+
    'hardware=bullhead,product=bullhead,platformVersionRelease=6.0.1,'+
    'model=Nexus%205X,buildId=MHC19Q,isWideScreen=0)'
);

const DOWNLOAD_MANAGER_USER_AGENT = (
  'AndroidDownloadManager/6.0.1 (Linux; U; Android 6.0.1; Nexus 5X Build/MHC19Q)'
);

Therefore you will have best luck getting an ANDROID_ID from a Nexus 5X or override the value via the options object for your particular device.

ID and User-Agent

Note that you'll need to grab the device-id (ANDROID_ID) and associated user-agents for best performance of the library.

ANDROID_ID - the ID for the device for Google. This is the GSF ID not the id from dialing *#*#8255#*#*. You can get the gsf id e.g., using this following app: device id app WARNING: This is not the androidId but the GSF Id that is needed by the library
Another way is to setup an HTTP proxy and install a CA to the device to see the network traffic. Here is an example from a mitmproxy session:

Device ID and API User-Agent

Download User-Agent

These values can then be passed to the API so that apps can be downloaded with the restrictions of the particular device.

requests defaults

Note that this library uses the requests module, therefore you can control proxy behavior or override defaults via the requestDefaultsParams option.

Debugging

Use env variable DEBUG i.e., DEBUG=gp:api to enable debug output. This is done via request-debug.

You can provide the debug option too.

{
  username: username,
  password: password,
  androidId: androidId,
  debug: false
}

EXAMPLES

Assumes you have set the following environment variables: GOOGLE_LOGIN, GOOGLE_PASSWORD, ANDROID_ID
