Access preparation

If you want to use API, please log in to the webpage first, finish the application of API key and permission configuration and then develop and trade according to the details of this document.

Each user can create 5 API Key and each API Key corresponds to setting two kinds of permission: Read and Trade.

All the data about frequency in the document is likely to be adjusted.

Permission description as follows:

Read permission: Read permission is used for data query interface, for example: order query, transaction query, etc.

Trade permission: Trade permission is used for the interface of placing orders and canceling orders.

After successful creation, please remember the following information:

Access Key: The key used in API request

Secret Key: The key used for signature authentication and encryption(Only visible at the point when you successfully create 2 strings of field)

It is requested to bind IP address when creating API Key. After boundation, you can use the trading interface. You cannot access the interface with an unbounded IP address.

Access type

Matrix provides two kinds of interface for uses, so you can choose an appropriate way to query the market and trade according to your usage scenario and your preference.

REST API

REST, the abbreviation for Representational State Transfer, is a currently popular communication mechanism based on HTTP. Each URL represents a kind of resource.

For one-time operations like trade, developers are recommended to use REST API.

WebSocket API

WebSocket is a new protocol of HTML5. It realizes full-duplex communication between client and server. It can establish the connection between client and server through one simple handshake. The server can actively push information to clients according to business rules.

Developers are recommended to use WebSocket API to achieve information like market data, trade depth, etc.

Access URLs

REST API

https://api.matrix.co/

Websocket Feed(Market data)

https://wss.matrix.co/

Interface authentication

1. Rest API and Websocket API both contain a public interface and a private interface.

2. Public interface can be used to obtain basic information and market data. Public interface can be used without authentication.

3. Private interface can be used to manage transactions and accounts. Every private request must use your API Key for signature authentication.

Signature authentication

API request is very likely to be tampered during the transmission through internet. In order to ensure the request not tampered, all the private interfaces except the public interface (basic information and market data) must use your API Key for signature authentication to verify whether parameter or parameter value is changed during the transmission. Each API Key needs appropriate permission to access the corresponding interface. Each newly created API Key needs to assign permission. Before using the interface, please check the permission type for each interface and confirm that your API Key has the corresponding permission.

A valid request consists of the following parts:

API path: Access the server address api.matrix.co，for example api.matrix.co/v1/order/orders. API access Id (API-KEY): Access Key in your API Key applied. API-SIGNATURE-METHOD: Hash-based signature authentication calculation, HmacSHA256 is used here API-SIGNATURE-VERSION: The version of the signature protocol, version 1 is used here. API-TIMESTAMP: Timestamp of your request time(the difference between the request time and current standard cannot be greater than 1min or this will be regarded as invalid).
For Get request, parameters that come with the method need signature calculation.
For POST request, parameters need to be put in body.
Signature: the value calculated by signature. It is used to ensure that signature is valid and is not tampered.

Signature step

Standardize the request that need to calculate signature. Because when using HMAC to calculate signature, calculating with different content, the result obtained will be completely different. Therefore, before calculating signature, please standardize the request first. The following is an example of query request for details of a certain order

Query the complete request URL, when searching for details of a certain order

https://api.matrix.co/v1/order/orders?orderId=1234567890

1. Request method(GET or POST, WebSocket using GET)，followed by a newline character “n”

   For example: GET\n

2. Add the lowercase access domain name, followed by a newline character “n”

   For example: api.matrix.co\n

3. The path of access method, followed by a newline character “n”

   Such as query an order: /v1/order/orders\n

4. Encrypt Header information

   API-KEY=AAAADAVYcB2SNK5wFIAMHA2E \n

   API-SIGNATURE-METHOD=HmacSHA256 \n

   API-SIGNATURE-VERSION=1 \n

   API-TIMESTAMP=1593516127982 \n

5. According to the order above, connect the parameters

   POST\napi.matrix.co\n/v1/order/orders\nAAAADAVYcB2SNK5wFIAMHA2E\nHmacSHA256\n1\n1593516127982

6. If it is a GET request

   Add corresponding request parameter at the end of the order above, For example: /v1/order/orders?currency=BTC, then the corresponding complete signature is GET\napi.matrix.co\n/v1/order/orders\nAAAADAVYcB2SNK5wFIAMHA2E\nHmacSHA256\n1\n1593516127982\ncurrency=BTC

   For example: /v1/order/trade/ticks/BTC_USD ,then the corresponding complete signature is GET\napi.matrix.co\n/v1/order/trade/ticks/BTC_USD\nAAAADAVYcB2SNK5wFIAMHA2E\nHmacSHA256\n1\n1593516127982

7. If it is a POST request

   Add corresponding JSON request body at the end of the order above

   For example: /v1/order/orders/place
   body is

       {
           "price":"1.0000",
           "amount":"1",
           "type":"BUY_LIMIT",
           "symbol":"ETH_USD",
           "triggerOn":"1.0000"
       }

   then the corresponding complete signature is POST\napi.matrix.co\n/v1/order/orders/place\nAAAADAVYcB2SNK5wFIAMHA2E\nHmacSHA256\n1\n1593516127982\namount=1&price=1.0000&symbol=ETH_USD&triggerOn=1.0000&type=BUY_LIMIT

   Note:
   In the body part of the POST request, the code will be parsed according to the positive order of ASCII code

   In the parameter part of the GET request, the code will be parsed according to the positive order of ASCII code

8. Use the "request string" generated in the previous step and your Secret Key to generate an electronic signature

   Regard the request string generated in the previous step and API private key as two parameters and use HmacSHA256 Hash functions to get Hash value Encode the Hash value with base-64. The value obtained is used as the eletronic signature of this interface-- 4F65x5A2bLyMWVQj3Aqp+B4w+ivaA7n5Oi2SuYtCJ9o=

9. Add the electronic signature into the request

   For Rest interface:

   Add all the parameters that must be verified into the Header parameters of interface After URL encoding, add the electronic signature into the Header parameters, with parameter name "API-SIGNATURE". Finally, the API request sent to the server should be https://api.matrix.co/v1/order/orders?orderId=1234567890

   headers:

       API-KEY:AAAADAVYcB2SNK5wFIAMHA2E
       API-SIGNATURE-METHOD: HmacSHA256
       API-SIGNATURE-VERSION: 1
       API-TIMESTAMP: 1593516127982
       API-SIGNATURE: 4F65x5A2bLyMWVQj3Aqp+B4w+ivaA7n5Oi2SuYtCJ9o=

    "status":"SUBMITTED",
    "filledSize":0,
    "orderId":183280
    }
}

Description:

1. clientOrderId

   Since Matrix will not promot rerangement tips, clientOrderId user need to guanrantee that this ID is not repetitive. If there is repetition, when you cancel or query orders, you can only cancel or query the latest piece of data.

2. type, price, amount and triggerOn field

   • limit price order: When the user order type is limit price order: type is BUY_LIMIT or SELL_LIMIT, amount is a required field at this time, price is unit price at this time

   For example:

   {"price":"1.0000","amount":"0","type":"BUY_LIMIT","symbol":"ETH_BTC"}

   • market order: When the user order type is market price order: type is BUY_MARKET or SELL_MARKET, amount is not required at this time, price is total price at this time. For example, if a user wants to buy 1 BTC, when currency pair is BTC_USD and market price is 9000, he can directly enter 9000.

   For example:

   {"price":"1.0000","type":"BUY_MARKET","symbol":"ETH_USD"}

   • stop-limit: When the user order type is stop-limit order: type is BUY_LIMIT or SELL_LIMIT, amount is required field at this time, price is unit price at this time triggerOn is required field at this time. If this is empty or trgigerOn is 0, this order is regarded as limit price order by default.

   For example:

   {
       "price":"1.0000",
       "amount":"1",
       "type":"BUY_LIMIT",
       "symbol":"ETH_USD",
       "triggerOn":"1.0000"
   }
