General

Introduction

gate.io provides a simple and robust Websocket API to integrate gate.io trade status into your business or application.

We have language bindings in JavaScript and Python, more in future! You can view code examples in the dark area to the right, and you can switch the programming language of the examples with the tabs in the top right.

Current Version

Websocket API version is v3.3.9.

Server URL

We provide two alternative server urls, you can choose one of them according to your condition.

TIP

wss://ws.gate.io/v3/

TIP

wss://ws.gateio.io/v3/

In code examples, we use ws.gate.io/v3 to present.

APIv4 Keys support

Spot websocket now supports APIv4 Keys. To use spot websocket with APIv4 keys, do the following change based on v3:

• Change server url version from /v3 to /v4
• Use APIv4 keys to generate signature
• Change the signature generation method to APIv4's, i.e., HexEncode(HMAC_SHA512(secret, signature_string)) and make sure nonce is current unix time in milliseconds.

For example, if current unix time in milliseconds is 1583131539528, your APIv4 key is key, secret is secret, the signature should be generated as (in Python code) hmac.new('secret', '1583131539528', hashlib.sha512).hexdigest(), and the result is 54613ee7f4236bf61bfaed71f10bc0cb8b24805c45822652f850812c9a43b2422cf84609197ccf5db7adaf5c6af5d143cf04646c2640ad89a7c89670b403b671 . Send request body to server.sign like:

{
  "id": 12312,
  "method": "server.sign",
  "params": [
    "key",
    "54613ee7f4236bf61bfaed71f10bc0cb8b24805c45822652f850812c9a43b2422cf84609197ccf5db7adaf5c6af5d143cf04646c2640ad89a7c89670b403b671",
    1583131539528
  ]
}

API Overview

Method

Each general api (such as ticker, depth, kline, etc.) supports 4 different method messages, they are:

1. query

   Active inquiry information of gate.io trade status. e.g. ticker.query

2. subscribe (RECOMMENDED TO USE)

   Subscribe to receive notification from server when new data is available. e.g. ticker.subscribe

3. unsubscribe

   Server will not send new data notification if unsubscribed. e.g. ticker.unsubscribe

4. update (CLIENT SHOULD NEVER SEND)

   If new subscribed data is available, server will send a notification to client. e.g. ticker.update

WARNING

User should NEVER send an update method message to server, because an update message is ALWAYS sent by server.

Request

Each request follows a common format, which contains id, method and params.

Server doesn't have strict restriction for request ID, but we strongly recommend you use different id for different api in one websocket connection.

parameter	type	required	description
id	Integer	Yes	the request ID
method	String	Yes	the method of request
params	Array	Yes	detail parameters

Response

Similar with request, response follows a common format compose of id, error and result.

field	type	description
id	Integer	corresponding to request ID
error	JSON object	null for success object with code and message for failure
result	JSON object	result object, null for failure

Notification

A notification message is sent for subscribed channels.

parameter	type	required	description
id	null	Yes	the request id, null for notification
method	String	Yes	method
params	Array	Yes	detail parameters

Error

In case of error, you receive a message containing the proper error code and message within an error object.

Code	Message
1	invalid argument
2	internal error
3	service unavailable
4	method not found
5	service timeout

Authentication

User can connect public channels without any particular authentication.

For private channels, gate.io provides a signature based authentication method. See Auth API for detail.

Limitation

WARNING

User can only execute maximum to 50 requests per second for each connected channel.

System API

Provides system status check, such as ping-pong and server time query.

Ping

function socket_send_cmd(socket, cmd, params) {
  if (!params) params = [];
  var msg = {
    id: client_id,
    method: cmd,
    params: params,
  };
  socket.send(JSON.stringify(msg));
}

var socket = new WebSocket("wss://ws.gate.io/v3");

socket.onopen = function () {
  console.log("Connected");
  socket_send_cmd(socket, "server.ping");
};
socket.onmessage = function (e) {
  console.log("Server: " + e.data);
};

from websocket import create_connection

ws = create_connection("wss://ws.gate.io/v3/")
ws.send('{"id":12312, "method":"server.ping", "params":[]}')
print(ws.recv())

The above command returns JSON structured like this:

{
  "error": null,
  "result": "pong",
  "id": 1000
}

Check server connectivity.

  console.log("Server: " + e.data);
};

from websocket import create_connection

Auth API

import hmac
import base64
import hashlib


def get_sign(secret_key, message):
    h = hmac.new(secret_key, message, hashlib.sha512)
    return base64.b64encode(h.digest())

gate.io provides a signature based authorization on private channels.

The algorithm can be simply described as below pseudo-code.

`base64(hmac_sha512(secret_key, nonce))`

You can refer to code example at the right.

Send authentication

import json
import time
from websocket import create_connection

api_key = 'your api key'
secret_key = 'your secret key'

ws = create_connection("wss://ws.gate.io/v3/")

nonce = int(time.time() * 1000)
signature = get_sign(secret_key, str(nonce))

ws.send(json.dumps({
    "id": 12312,
    "method": "server.sign",
    "params": [api_key, signature, nonce]
}))
print(ws.recv())

The above command returns JSON structured like this:
