BitGo provides a simple and robust RESTful API and client SDK to integrate digital currency wallets with your application. In Platform V2, we have extended our API and SDK to allow the management of multiple digital currencies and wallets through a single, unified interface.

The BitGo SDK enables the following:

• Creation of multi-signature wallets
• Wallet balance and transaction listing
• Transaction creation and signing
• Transaction monitoring and notifications
• Secure user authentication
• Multi-user workflows for use in enterprise environments
• Policies and spending limits

This is the latest documentation for the BitGo APIs, and is generated from OpenAPI 3.0 schema. OpenAPI technology provides improved validation of client requests, and more consistency between the API documentation and server-side implementation of API endpoints.

Legacy users may also refer to the V1 Bitcoin API, which is still available today. There is no dependency for developers to integrate with V1 or read the legacy documentation in order to take advantage of the newer version of our API.

The primary advantage of multi-signature wallets is the ability for multiple machines and people to work together to approve a given transaction. Without multiple signatures on a transaction, all credentials to approve a transaction must reside with a single person on a machine. If that person or machine is compromised by an attacker, all funds can be taken with no recourse and no ability to audit the individual that invoked the key.

BitGo's multi-signature wallets allow you to keep control of your Bitcoin or other cryptocurrency despite introducing the concept of a co-signer. This allows enterprises to set up and maintain roles, policies, and rules on the wallet, making digital currency usable for businesses.

For more information, please read the BitGo Whitepaper.

All calls to endpoints that require authentication must pass the client access token via the Authorization HTTP header. The format of this header is Authorization: Bearer <TOKEN>. Here's an example that uses HTTPie to call the Get session API from the command line:

$ http -v get https://app.bitgo-test.com/api/v2/user/me Authorization:"Bearer $TEST_TOKEN"
GET /api/v2/user/me HTTP/1.1
Accept: */*
Accept-Encoding: gzip, deflate
Authorization: Bearer v2x83...
Connection: keep-alive
Host: app.bitgo-test.com
User-Agent: HTTPie/1.0.0

HTTP/1.1 200 OK
...

You can create an access token in the "Developer Options" tab of the web UI, under "User Settings." An access token can limit access in several ways:

• Expiration date
• Allowed operations
• Allowed client IP addresses

Security note

BitGo's SDK and Express App secures tokens using our Auth V2 protocol, which does not send the access token over the wire. For this reason, we recommend that API requests from 3rd party clients should be proxied through BitGo Express.

The BitGo web APIs provide developers with the capability to create and manage multi-signature wallets, manipulate their policies and interact with multiple digital currencies over a single robust interface. Several sensitive operations, such as the creation of user private keys and signing of transactions, must to be performed client-side.

For this reason, we provide and recommend the use of our Software Development Kit (SDK), which implements these client-side wallet features and interfaces with our APIs.

Currently, our SDK is available in JavaScript and runs in either Node.js or a browser. If your application does not use native JavaScript, you may refer to the BitGo Express REST API guide, which offers the same feature set via a local server daemon.

Installing the JavaScript SDK (via npm)

npm install --save bitgo

To initialize your environment and authenticate, use the following code:

const BitGoJS = require('bitgo');
// Read the user authentication section to get your API access token
const bitgo = new BitGoJS.BitGo({ env: 'test', accessToken: process.env.ACCESS_TOKEN });
const coin = bitgo.coin('tbtc');

The BitGo Express REST API is a lightweight service for developers who want to use the BitGo service, but are developing in a language other than JavaScript.

BitGo Express runs as a service in your own data center, and handles the client-side operations involving your own keys, such as partially signing transactions before submitting them to BitGo. This ensures your keys never leave your network, and are never seen by BitGo. BitGo Express can also proxy the standard BitGo REST APIs, providing a unified interface to BitGo through a single REST API.

We recommend using Docker to run BitGo Express, and we also support running from the source code directly.

To try out BitGo Express, run this command:

docker run -it -p 3080:3080 bitgosdk/express:latest

You should see this output from BitGo Express:

BitGo-Express running
Environment: test
Base URI: http://0.0.0.0:3080

Now you can send a ping request to BitGo Express using curl to make sure the service is up and running:

$ curl localhost:3080/api/v2/ping
{"status":"service is ok!","environment":"BitGo Testnet","configEnv":"testnet","configVersion":79}

• Make all BitGo REST API calls to the machine on which bitgo-express is running. BitGo Express will either handle the request itself or proxy it to the BitGo service.

For more detailed information, please see the BitGo Express README.

BitGo has two separate environments available for development and production. For security reasons, all BitGo API requests are made using TLS over HTTPS.

Test Environment

The BitGo test environment is used by default in our examples and the SDK. It is entirely separate from BitGo's production environment and there is no overlap in either data or accounts. You will need to create accounts at app.bitgo-test.com.

• BitGo Test Site: https://app.bitgo-test.com/
• Test Environment API: https://app.bitgo-test.com/docs

In the test environment, you can use 0000000 in place of the OTP when authenticating.

This environment is connected to the TestNet networks of various digital currencies we support. Tokens on these networks can be obtained from faucets and do not represent real money.

Production Environment

The BitGo production endpoint is live and used by partners and our own web application on app.bitgo.com.

• Production Site: https://app.bitgo.com/
• Production API: https://app.bitgo.com/docs

To use this environment, specify { env: 'prod' } when using the SDK or -e prod when running BitGo Express. SSL certifications should be provided to secure traffic to and from the BitGo Express instances when operating on the Production environment.

BitGo Platform V2 supports a variety of digital currencies, with more being added every quarter.

To select the coin or token:

var bitgo = new BitGoJS.BitGo({ env: 'test', accessToken: process.env.ACCESS_TOKEN });
var coin = bitgo.coin('btc');

(replace btc with your desired coin identifier)
