Introduction - WARNING - THIS API VERSION HAS BEEN SUPERSEDED

The Bitso API allows you to integrate the Bitso trading platform with third party applications, such as trading applications, charting programs, point of sale systems, and much more. Below you will find details on how the system functions, along with examples in common programming languages.

General

General Information about Bitso’s APIs

HTTP and WebSocket APIs

Bitso offers a HTTP API, and a WebSocket API. The HTTP API exposes both public and private functions. The WebSocket API offers realtime streaming of market-data, such as the Bitso orderbook state.

Transfer API

Bitso’s powerful Transfer API allows for simple integration for routing Bitcoin payments directly through to a choice of Mexican Peso end-points. Please contact us if you’re interested in using this API, access is available on request.

Notations

Major denotes the cryptocurrency, in our case Bitcoin (BTC).

Minor denotes fiat currencies such as Mexican Peso (MXN), etc

An order book is always referred to in the API as “Major_Minor”. For example: “btc_mxn”

Precision

We return decimal numbers as strings to preserve full precision across platforms. We recommend you also convert your numbers to string in order to avoid undesired consequences from precision and truncation errors.

Rate Limits

Rate limits are are based on one minute windows. If you do more than 30 requests in a minute, you get locked out for one minute.

Client Libraries

The following client libraries will allow you to integrate quickly with our APIs

• Java
• NodeJS
• .NET
• Python
• Objective-C

Private Endpoints

Private endpoints are used to manage your account and your orders. These requests must be signed (more about this below).

Generating API Keys

Bitso uses API Keys to allow access to the API. You can register a new Bitso API key at our developer portal.

When setting up a new API, you will need to choose an API Name to identify your API. This name will never be shown anywhere apart from on your API Index page within your account. You have the option of adding a Withdrawal Bitcoin Address, which can be used to lock the API Withdrawal function to a specific Bitcoin address of your choosing. This field is optional.

The three key elements you will need to sign requests are:

• Bitso API Key
• Bitso API Secret
• Bitso Client ID

Creating and Signing Requests

var secret = "BITSO API SECRET";
var key = "BITSO API KEY";
var client_id = "BITSO CLIENT ID";
var nonce = new Date().getTime();

// Create the signature
var Data = nonce + client_id + key;
var crypto = require('crypto');
var signature = crypto.createHmac('sha256', secret).update(Data).digest('hex');

// Build the request parameters
var querystring = require('querystring');
var data = querystring.stringify({
  key: key,
  nonce: nonce,
  signature: signature
});
var options = {
  host: 'api.bitso.com',
  port: 443,
  path: '/v2/balance',
  method: 'POST',
  headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
    }
};

// Send request
var http = require('https');
var req = http.request(options, function(res) {
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});
req.write(data);
req.end();

All REST requests should be valid JSON. You need to POST 3 fields as a JSON payload to the API in order to perform authentication:

• key – The API Key you generated
• nonce – An integer that must be unique and increasing for each API call (we recommend using a UNIX timestamp)
• signature – See below

Signature

The signature is generated by creating a SHA256 HMAC using the Bitso API Secret on the concatenation of nonce + Bitso Client ID + Bitso API Key (no ’+’ signs in the concatenated string) and hex-encode the output. The nonce value should be the same as the nonce field in the json dictionary.

Account balance

The JSON dictionary returned by the API looks like this:

{
    "btc_available": "46.67902107",
    "fee": "1.0000",

    "btc_balance": "46.67902107",
    "mxn_reserved": "0.00",
    "mxn_balance": "26864.57",

WebSocket API

General

The Orders channel maintains an up-to-date list of the top 20 asks and the top 20 bids, new messages are sent across the channel whenever there is a change in either top 20.

The Diff-Orders channel will send across any modifications to the order book. Specifically, any state changes in existing orders (including orders not in the top 20), and any new orders. An order could be removed, in which case it won’t have an ‘a’ field (amount), or am order could have been partially filled (you can look up an order’s state via the lookup_order endpoint) which will be reflected in the amount field. In theory, you can get a copy of the full order book via REST once, and keep it up to date by using the diff-orders channel.

An order’s timestamp field is immutable. Even if the amount field is mutated, or the order removed, the timestamp field remains as it was when the order was created. Note that a timestamp is not unique. Different orders can have the same timestamp.

How to connect

Create a WebSocket instance:

websocket = new WebSocket('wss://ws.bitso.com');

Subscribe to each channel you wish to connect to:

websocket.onopen = function() {
    websocket.send(JSON.stringify({ action: 'subscribe', book: 'btc_mxn', type: 'trades' }));
    websocket.send(JSON.stringify({ action: 'subscribe', book: 'btc_mxn', type: 'diff-orders' }));
    websocket.send(JSON.stringify({ action: 'subscribe', book: 'btc_mxn', type: 'orders' }));
};

The server will acknowledge each subscription to a channel with a message. For example, a successful subscription to the 'trades’ channel will be acknowledged in the following manner:

{action: "subscribe", response: "ok", time: 1455831538045, type: "trades"}

Once you’ve succesfuly subscribed to a channel, listen for messages and handle them appropriately:

websocket.onmessage = function(message){
                var data = JSON.parse(message.data);

                if (data.type == 'trades' && data.payload) {

                }
                else if (data.type == 'diff-orders' && data.payload) {

                }
                else if (data.type == 'orders' && data.payload) {

                }
            };

Transfer API

General

Bitso’s powerful Transfer API allows for simple integration for routing Bitcoin payments directly through to a choice of Mexican Peso end-points.

The workflow breaks down in the following steps:

1. Request quote
2. Create transfer using quote
3. Send bitcoins to address given
4. After 1 confirmation, pesos are delivered

The quote acquired in step #1 is valid for 60 seconds. Once this is used to create a transfer (#2), that transfer is then valid for 60 seconds from creation (within which time the Bitcoin transaction to satisfy it must be ‘seen’ by our servers – this typically happens within 20 seconds).

Once the transfer is satisfied, the Bitcoin transaction must be confirmed before a further action takes place. Typically this takes around a maximum of 10 minutes, but can be a little longer.

The transfer can be monitored throughout the process by making a request to the URL returned with the transfer creation.

Authentication

The Transfer API is accessible via an API key created for your account. For full details on creating an API key and how to sign your API requests, please refer to: the authentication section

Currently Available Outlets

SPEI

SPEI is Mexico’s lightning fast and inexpensive inter-bank transfer system (akin to SEPA in Europe, and vastly superior to ACH).

All bank accounts in Mexico can be identified by their special 18-digit SPEI account number, otherwise known as a ‘CLABE’.

Transfers executed via SPEI are typically concluded within a few seconds (within banking hours).

Pademobile

Pademobile is a popular mobile wallet and payments system in Latin America and beyond. Users running the Pademobile wallet on their cellphone can carry a balance in local currency, and spend it at a variety of locations, including cash-out at stores such as 7-Eleven (this is limited to 300 MXN per day, per location).

Pademobile accounts are identified simply by the user’s phone number. Recipients who do not have smart phones, or who have not installed the wallet app, will receive a text message containing instructions on how to access the received funds.

For more information, please see: https://www.pademobile.com/en/mx/

Ripple

As a Ripple Gateway, Bitso is able to issue currencies such as the Mexican Peso directly into the Ripple Network. For more information on Ripple, please see: https://ripple.com/

Voucher
