coinbase-java

A java wrapper around the coinbase REST APIs

Dependencies:

• google-gson
• apache httpclient-4.3.1

Supported APIs

• Authentication
• Get current user
• list addresses (page, limit, and query support)
• generate recieve address
• buy
• sell
• list transactions
• get transaction details
• send money
• request money
• resend money request
• cancel money request
• complete money request
• buttons

Usage:

All work is done via the CoinbaseApi class. You can construct an instance of this class one of three ways:

//Constructs an instance of CoinbaseApi using OAuth
CoinbaseApi api = new CoinbaseApi(clientId, clientSecret, redirectUrl);

//Constructs an instance of CoinbaseApi using and api key
CoinbaseApi api = new CoinbaseApi(apiKey);

//Constructs an instance of CoinbaseApi using OAuth, but providing an access token and refresh token up front
CoinbaseApi api = new CoinbaseApi(clientId, clientSecret, redirectUrl, accessToken, refreshToken);

OAuth: If you are using OAuth as your authentication mechanism, you will first need to authenticate. coinbase-java only supports coinbase's new three-legged OAuth and there are no plans to support their old, deprecated two-legged OAuth.

The first thing you need to do is generate an authentication URL. You can do this by calling:

String authUrl = api.generateOAuthUrl();

Then, the user will need to use this url to obtain an authentication code. Once the code is in hand, to authenticate, simply do

//get the auth code using the authUrl
if (api.authenticate(code)) {
    //auth success
} else {
    //auth failed
}

For information on coinbase's three-legged auth, see here.

HttpClient vs. HttpURLConnection By default, coinbase-java uses apache's HttpClient libraries for connections. If you are using a service such as Google App Engine that doesn't support these libraries or handles secure connections on its own, you can choose to use HttpURLConnection instead by doing

api.allowSecure(false);

coinbase-java's Issues

variable price is not working

if i pass true for isVariablePrice in makeButton,it does not show any changes,price is still fixed and not-editable..

Shouldn't care about specific server type

Right now, It defaults to "non-google app engine", but it assumes non-google app engine means apache. We have a private data member for "apache" and accessor methods for isApache() and setApache(). The data member should be changed to "secure" and default to true. The methods should be changed to isSecure() and setSecure().

Coinbase Button api needs to work with secure connections
