The official Node.js library for the Coinbase API.
- Full Test coverage.
- Support for both API Key + Secret and OAuth 2 authentication.
- Convenient methods for making calls to the API.
- Automatic parsing of API responses into relevant Javascript objects.
- Adheres to the nodejs error-first callback protocol.
- Continuous Integration testing against node 0.10, 0.11, and 0.12.

Npm coinbase package name used to refer to the unofficial coinbase library maintained by Matt Walters. Matt graciously allowed us to use the name for this package instead. You can still find that package on Github. Thanks, Matt.
The first thing you'll need to do is sign up for coinbase.
If you're writing code for your own Coinbase account, enable an API key. Next, create a Client object for interacting with the API:
var Client = require('coinbase').Client;
var client = new Client({'apiKey': mykey, 'apiSecret': mysecret});If you're writing code that will act on behalf of another user, start by creating a new OAuth 2 application. You will need to do some work to obtain OAuth credentials for your users; while outside the scope of this document, please refer to our OAuth 2 tutorial and documentation. Once you have these credentials, create a client:
var Client = require('coinbase').Client;
var client = new Client({'accessToken': accessToken, 'refreshToken': refreshToken});With a client instance, you can now make API calls. We've included some examples below, but in general the library has Javascript prototypes for each of the objects described in our REST API documentation. These classes each have methods for making the relevant API calls; for instance, coinbase.model.Transaction.complete maps to the complete bitcoin request API endpoint. The comments of each method in the code references the endpoint it implements. Each API method returns an object representing the JSON response from the API.
Listing available accounts
var coinbase = require('coinbase');
var client = new coinbase.Client({'apiKey': mykey, 'apiSecret': mysecret});
client.getAccounts({}, function(err, accounts) {
accounts.forEach(function(acct) {
console.log('my bal: ' + acct.balance.amount + ' for ' + acct.name);
});
});Get Balance from an Account Id
var coinbase = require('coinbase');
var client = new coinbase.Client({'apiKey': mykey, 'apiSecret': mysecret});
client.getAccount('<ACCOUNT ID>', function(err, account) {
console.log('bal: ' + account.balance.amount + ' currency: ' + account.balance.currency);
});Selling bitcoin
var args = {
"amount": "12",
"currency": "BTC"
};
account.sell(args, function(err, xfer) {
console.log('my xfer id is: ' + xfer.id);
});Sending bitcoin
var args = {
"to": "[email protected]",
"amount": "1.234",
"currency": "BTC",
"description": "Sample transaction for you"
};
account.sendMoney(args, function(err, txn) {
console.log('my txn id is: ' + txn.id);
});Requesting bitcoin
var args = {
"to": "[email protected]",
"amount": "1.234",
"currency": "BTC",
"description": "Sample transaction for you"
};
account.requestMoney(args, function(err, txn) {
console.log('my txn id is: ' + txn.id);
});Listing current transactions
account.getTransactions(null, function(err, txns) {
txns.forEach(function(txn) {
console.log('my txn status: ' + txn.status);
});
});Using pagination
account.getTransactions(null, function(err, txns, pagination) {
txns.forEach(function(txn) {
console.log('my txn: ' + txn.id);
});
console.log(pagination.next_uri);
account.getTransactions(pagination, function(err, txns) {
txns.forEach(function(txn) {
console.log('my txn: ' + txn.id);
});
});
});Checking bitcoin prices
client.getBuyPrice({'currencyPair': 'BTC-USD'}, function(err, obj) {
console.log('total amount: ' + obj.data.amount);
});Verifying merchant callback authenticity
if (client.verifyCallback(req.raw_body, req.headers['CB-SIGNATURE'])) {
// Process callback
}Errors are thrown for invalid arguments but are otherwise returned as the first argument to callback functions using http-errors module.
Errors contain name, status, and message fields for error handling. You can find
more information about error types here
