Introduction

All shell commands are CURL. You can read more about CURL here.

HollaEx provides a complete RESTful API for developers which allows full access to all the functionalities on the exchange. HollaEx also support websocket for real-time updates.

These endpoints are categorized into public and private. Public endpoints allow you to access public information such as price ticker, orderbook etc while private endpoints require authentication and allow you to get your balance, active orders as well as placing orders.

We have language bindings in Shell with CURL and you can view code examples in the dark area on the right.

Authentication

To authorize, use this code:

# With shell, you can just pass the correct header with each request
curl -X POST
  -H "api-key: $API_KEY"
  -H "api-signature: $API_SIGNATURE"
  -H "api-expires: $API_EXPIRES"
  "api_endpoint_here"

Make sure to replace $API_KEY, $API_SIGNATURE, and $API_EXPIRES with your own key, signature, and expires values.

HollaEx uses HMAC-SHA256 authentication for private user access to the API. HMAC-SHA256 takes a string and secret key (your api-secret) and outputs an encoded signature (your api-signature). The string being encoded should follow the format ${METHOD}${PATH}${api-expires}, where METHOD is the HTTP method of the request, PATH is the path of the request, and api-expires is a unix timestamp indicating when the request expires. If the request includes a body, the JSON body object should be appended to the string being encoded e.g. ${METHOD}${PATH}${api-expires}${JSON_BODY}. You can use an online HMAC generator to generate the signature.

Examples of strings being encoded:

You can register for a new HollaEx api-key and api-secret in the security section of hollaex.com.

HollaEx expects api-key, api-signature, and api-expires to be included in all Private API requests to the server in the request header with the following format:

api-key: <API_KEY>
api-signature: <API_SIGNATURE>
api-expires: <API_EXPIRES>

Websocket

Connection to public and private channels are available through the path https://api.hollaex.com/stream. HollaEx Exchanges can be connected to using any websocket libraries. For this documentation, we will use the library ws.

Connecting

Connection


    const WebSocket = require('ws');

    // Public
    const client = new WebSocket('https://api.hollaex.com/stream');

    // Private Bearer
    const client = new WebSocket(`https://api.hollaex.com/stream?authorization=Bearer%20${TOKEN}`);

    // Private HMAC
    const client = new WebSocket(`https://api.hollaex.com/stream?api-key=${API-KEY}&api-signature=${API-SIGNATURE}&api-expires=${API-EXPIRES}`);

    client.on('open', () => {
        // Ping message to keep connection alive
        setInterval(() => {
            client.send(
                JSON.stringify({
                    op: 'ping'
                })
            )
        })
    }, 30000);

Connection for public events does not require authentication while private events do. Users can use Bearer or HMAC authentication. For HMAC, the method is CONNECT and the path is /stream. Refer to the Authentication section for more information on HMAC-SHA256.

Websocket connections will disconnect if a message is not sent within one minute. To keep a connection alive, you can sent a ping message every ~30 seconds.
