Tradedo Exchange REST API Documentation

Welcome to the Tradedo Exchange REST API documentation. This API (Application Programming Interface) will allow you to access the functionality of this exchange by means of HTTP requests, making integration with your own applications possible.

Connecting to the API

You can access the API at the following url:

https://tradedo.io/api

You are permited to make up to 60 requests a minute.

Usage

In order to use a public API method, you must make an HTTP request to the appropriate endpoint for that particular method, sending the appropriate GET or POST parameters for that method. You can also send them in the PAYLOAD of the request in JSON format.

To access protected API methods, you must obtain an API key/secret pair. Their usage is explained further ahead in this document.

Here are a few basic usage examples:

# Example request using CURL on the command line
curl "https://tradedo.io/api/index.php?endpoint=transactions" \
-d currency="BTC" \
-d limit=5

// Example valid response
{"transactions": {
    "0":{"id":"131","date":"2014-11-13 10:42:46","aur":"1.00000000","maker_type":"buy","price":"10.00","amount":"10.00","currency":"BTC"},
    "1":{"id":"129","date":"2014-11-11 11:14:12","aur":"0.50000000","maker_type":"buy","price":"11.27","amount":"5.63","currency":"BTC"},
    "2":{"id":"128","date":"2014-11-11 11:13:49","aur":"0.50000000","maker_type":"buy","price":"10.91","amount":"5.46","currency":"BTC"},
    "3":{"id":"127","date":"2014-11-10 18:29:15","aur":"0.50000000","maker_type":"buy","price":"11.20","amount":"5.60","currency":"BTC"},

    "request_currency":"BTC"
    }
}

// Example error response
{"errors":[{"message":"Invalid currency.","code":"INVALID_CURRENCY"}]}

Public API Methods

These methods can be accessed without an account or API key.

Generate Signature

To generate signature, you must include the following parameters in your POST parameters or the JSON PAYLOAD of your request:

POST https://tradedo.io/api/index.php?endpoint=generate-signature

Parameters:

api_key (string) - The API key that you generated.
api_secret (string) - The API secret that was generated together with the api_key

Response:

signature(string) - An HMAC-SHA256 signature of the JSON-encoded parameters of the request, signed using the API secret that was generated together with the api_key. These parameters include the api_key and nonce. This signature should then be added to the request parameters.
nonce (int) - A random integer.

Protected API Methods

In order to access these methods, you must obtain an API key/secret pair to authenticate your request.

Obtaining An API Key

To get access to our API, you must generate an API key on the API Access page. You must have two-factor authentication enabled on your account to be able to view this page. Upon generating a new API key, you will be given an API secret code. This value will only be shown to you once. Please store it in a secure place, as you will need it to use it together with your API key.

Once you have generated an API key, you can allow or restrict it's holder's access to the parent account's functionality by checking or unchecking the checkboxes in the "permissions" line under the API key.

Authenticating Your Request

To authenticate a request with your API key/secret pair, you must include the following parameters in your POST parameters or the JSON PAYLOAD of your request:

api_key (string) - The API key that you generated.
nonce (int) - A random integer. Each request must have a higher nonce than the last one. You can use the current UNIX timestamp for example.
signature (string) - An HMAC-SHA256 signature of the JSON-encoded parameters of the request, signed using the API secret that was generated together with the api_key. These parameters include the api_key and nonce. This signature should then be added to the request parameters.

We know that generating a signature might be a bit intimidating if you're doing it for the first time, so please see the following examples:

// Javascript Example
    
// Uses http://crypto-js.googlecode.com/svn/tags/3.0.2/build/rollups/hmac-sha256.js
// ...and http://crypto-js.googlecode.com/svn/tags/3.0.2/build/components/enc-base64-min.js

// we add our public key and nonce to whatever parameters we are sending
var params = {};
params.currency = "btc";
params.price = 200;
params.api_key = api_key;
params.nonce = Math.round(new Date().getTime() / 1000);
    
// create the signature
var hash = CryptoJS.HmacSHA256(CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(JSON.stringify(data))), api_secret).toString()
    
// add signature to request parameters
params.signature = hash;

// PHP Example
    
// we add our public key and nonce to whatever parameters we are sending
$commands['side'] = 'sell';
$commands['type'] = 'stop';
$commands['api_key'] = $api_key;
$commands['nonce'] = time();
    
// create the signature
$signature = hash_hmac('sha256', base64_encode(json_encode($commands)), $api_secret);
    
// add signature to request parameters
$commands['signature'] = $signature;

# Python Example
    
import hashlib
import hmac
    
// we add our public key and nonce to whatever parameters we are sending
params = {'currency': 'btc', 'price': 200, 'api_key': api_key, 'nonce': time.time()}

// create the signature
message = bytes(json.dumps(params)).encode('utf-8')
secret = bytes(api_secret).encode('utf-8')
signature = hmac.new(secret, message, digestmod=hashlib.sha256).hexdigest()
    
// add signature to request parameters  
params['signature'] = signature

// C# Example
    
using System.Security.Cryptography;

// we add our public key and nonce to whatever parameters we are sending
var params1 = new List>();
params1.Add(new KeyValuePair("api_key", api_key));
params1.Add(new KeyValuePair("nonce", (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds));
    
// create the signature
JavaScriptSerializer serializer = new JavaScriptSerializer();
var message = serializer.Serialize(params1);
    
secret = secret ?? "";
var encoding = new System.Text.ASCIIEncoding();
byte[] keyByte = encoding.GetBytes(secret);
byte[] messageBytes = encoding.GetBytes(message);
using (var hmacsha256 = new HMACSHA256(keyByte))
{
    byte[] hashmessage = hmacsha256.ComputeHash(messageBytes);
    var signature = BitConverter.ToString(hashmessage);
    signature = signature.Replace("-", "");
    
    // add signature to request parameters
    params1.Add(new KeyValuePair("signature", signature));
}

/* Java Example */
    
/* Dependent on Apache Commons Codec to encode in base64. */
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Hex;

/* we add our public key and nonce to whatever parameters we are sending */
Map params = new HashMap();
params.put("api_key", "demo");
params.put("nonce", ((int) (System.currentTimeMillis() / 1000L)));
    
/* create the signature */
String secret = "secret";
String message = new JSONObject(params).toString();

Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(), "HmacSHA256");
sha256_HMAC.init(secret_key);

String hash = Hex.encodeHexString(sha256_HMAC.doFinal(message.getBytes()));

/* add signature to request parameters */
params.put("signature", hash);
