Zabo SDK for JS

What is Zabo? A unified cryptocurrency API.

CircleCI Discord Discourse

Zabo is an API for connecting with cryptocurrency exchanges, wallets and protocols like Bitcoin. Instead of manually integrating with Coinbase API, Binance API, Bitcoin APIs or the hundreds of other cryptocurrency APIs - you can simply use Zabo for them all.

We believe teams and developers should focus on building great products, not worry about the fragmented landscape of exchange APIs and blockchain protocols.

For our updated list of integrations, check out our Zabo integrations.

Zabo API Javascript (JS) SDK

The Zabo SDK for JS provides convenient access to the Zabo API from applications written in browser and server-side JavaScript.

Please keep in mind that you must register and receive a team id to use in your client application, or if you are using the server side functions, generate an API keypair from your dashboard.

Documentation

See the Zabo API docs.

Installation

For a standard browser application, add the script tag to your html file:

<script src="https://cdn.zabo.com/develop/latest/zabo.js">

As a package:

npm install zabo-sdk-js --save

Usage

The first step is always to allow a user to connect from your front-end:

<!DOCTYPE html>
<html lang="en" dir="ltr">

<head>
  <meta charset="utf-8">
  <title>My Website</title>

  <link rel="stylesheet" href="example.css" type="text/css" />
</head>

<body>
  <section>
    <header>
      <h2>My Zabo Application</h2>
    </header>

    <button id="connect" type="button">Connect</button>

    <div>
      <h4>Other SDK methods</h4>
      <button id="getBalance" type="button">Crypto Balances</button>
      <button id="getHistory" type="button">Account History</button>
      <button id="getExchangeRates" type="button">Exchange Rates</button>
    </div>

  </section>

  <!--Add this script to your html file-->
  <script src="https://cdn.zabo.com/latest/zabo.js"></script>

  <script type="text/javascript">
    // Wait for document to fully load
    document.onreadystatechange = async () => {
      if (document.readyState !== 'complete') { return }

      const output = document.querySelector('#output')

      // Initiate Zabo SDK, replace the `clientId` field with your team client id.
      const zabo = await Zabo.init({
        clientId: 'YourClientIDFromTheZaboDotComDashboard',
        env: 'sandbox'
      })
      // Bind "connect" button
      document.querySelector('#connect').addEventListener('click', ev => {
        // Call connect when pressed and provide default .connect() window.
        zabo.connect().onConnection(account => {
          console.log('account connected:', account)
          bindOtherMethods()
        }).onError(error => {
          console.error('account connection error:', error.message)
        })
      })

      // Bind buttons for the other SDK example methods [Requires a successful zabo.connect() first]
      function bindOtherMethods () {
        document.querySelector('#getBalance').addEventListener('click', ev => {
          // Get ETH balance
          zabo.accounts.getBalances({ currencies: ["ETH"] }).then(balances => {
            console.log(balances)
          }).catch(error => {
            /* User has not yet connected or doesn't have an ether wallet */
            console.error(error)
          })
        })

        document.querySelector('#getHistory').addEventListener('click', ev => {
          // Get account transactions history
          zabo.transactions.getList({ currency: 'ETH' }).then(history => {
            console.log(history)
          }).catch(error => {
            /* User has not yet connected */
            console.error(error)
          })
        })

        document.querySelector('#getExchangeRates').addEventListener('click', ev => {
          // Get crypto USD exchange rates
          zabo.currencies.getExchangeRates().then(rates => {
            console.log(rates)
          }).catch(error => {
            console.error(error)
          })
        })
      }
    }
  </script>
</body>

</html>

Or importing as a package:

const Zabo = require('zabo-sdk-js')

const zabo = await Zabo.init({
  clientId: 'YourClientIDFromTheZaboDotComDashboard',
  env: 'sandbox'
})

zabo.connect().onConnection(account => {
  console.log('account connected:', account)
}).onError(error => {
  console.error('account connection error:', error.message)
})

Or using ES6 modules:

import Zabo from 'zabo-sdk-js'

After connecting

After a user connects, the client SDK can continued to be used for the connected wallet:

zabo.transactions.getList({ currency: 'ETH' }).then(history => {
  console.log(history)
}).catch(error => {
  /* User has not yet connected */
  console.error(error)
})

Or you can send the account to your server for the server-side SDK to create a unique user:

zabo.connect().onConnection(account => {
  sendToYourServer(account)
}).onError(error => {
  console.error('account connection error:', error.message)
})

// Then in your server
const Zabo = require('zabo-sdk-js')
let account = accountReceivedFromTheClient

Zabo.init({
  apiKey: 'YourPublicAPIKeyGeneratedInYourZaboDotComDashboard',
  secretKey: 'YourSecretAPIKey',
  env: 'sandbox'
}).then(zabo => {
  zabo.users.create(account)
}).catch(e => {
  console.log(e.message)
})

Zabo.init() Configuration

While instantiating your new Zabo SDK instance, you have a few configuration options that can be changed to best suit your needs. Please note that some options are available only when running the SDK from the browser while others are available when running the SDK on your node.js code.

KeyDescriptionPlatform
clientIdApp Key acquired when registering a team in Zabo Dashboard.Browser
envZabo API environment the SDK is connecting with. Could be either sandbox or live. Only sandbox is available unless a live connection is approved.Both
apiKeyAPI Key generated via the Developer Settings section at Zabo Dashboard.Node
secretKeySecret Key generated via the Developer Settings section at Zabo Dashboard.Node
autoConnectOptional boolean useful if you wish to stop the SDK from fetching the team data during Zabo.init(). Defaults to true.Both

Server vs Client

The SDK can be used in either the client or server environment after a user connects their wallet, however, they have different functions available to them and utilize different authentication methods. See the Zabo API docs for more information.

Using Promises

Every method returns a chainable promise which can be used:

zabo.getTeam().then(a => {
  console.log(a)
}).catch(e => {
  console.log(e.message)
})

Or with async/await:

let exchangeRates = await zabo.currencies.exchangeRates()
console.log(exchangeRates)
