Changekon API

Table of Contents :

General API Information

Endpoint security type

  • Each endpoint has a security type that determines the how you will interact with it. This is stated next to the NAME of the endpoint.
    • If no security type is stated, assume the security type is NONE.
  • API-keys are passed into the Rest API via the PUBKEY header.
  • API-keys and secret-keys are case sensitive.
  • API-keys can be configured to only access certain types of secure endpoints. For example, one API-key could be used for TRADE only, while another API-key can access everything except for TRADE routes.
  • By default, API-keys can access all secure routes.
Security Type Description
MARKET_DATA Endpoint can be accessed freely.
ORDER Endpoint requires sending a valid API-Key and signature.
USER_DATA Endpoint requires sending a valid API-Key and signature.
WALLET_DATA Endpoint requires sending a valid API-Key and signature.
  • ORDER and USER and WALLET endpoints are SIGNED endpoints.

SIGNED (TRADE and USER_DATA) Endpoint security

  • SIGNED endpoints require an additional parameter, signature, to be sent in the query string or request body.
  • Endpoints use HMAC SHA256 signatures. The HMAC SHA256 signature is a keyed HMAC SHA256 operation. Use your secretKey as the key and totalParams as the value for the HMAC operation.
  • The signature is case sensitive.
  • totalParams is defined as the query string concatenated with the request body.

Timing security

  • A SIGNED endpoint also requires a parameter, timestamp, to be sent which should be the millisecond timestamp of when the request was created and sent.

  • An additional parameter, recvWindow, may be sent to specify the number of milliseconds after timestamp the request is valid for. If recvWindow is not sent, it defaults to 5000.

  • The logic is as follows:

    if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow) {
  // process request
} else {
  // reject request
}

    Serious trading is about timing. Networks can be unstable and unreliable, which can lead to requests taking varying amounts of time to reach the servers. With recvWindow, you can specify that the request must be processed within a certain number of milliseconds or be rejected by the server. It is recommended to use a small recvWindow of 5000 or less! The max cannot go beyond 60,000!

SIGNED Endpoint Examples for GET /api/v1/order/buy

Here is a step-by-step example of how to send a vaild signed payload from the Linux command line using curl.

Key Value
apiKey Xm89ak2z8cA2MjP4ywRlshyeOboAkZI9rDBNWjKu58DCiTUgrmJGfsbxCrmFcYcz
secretKey QvZYxOALthYZS9rkGbXxTSfKwc1vS1NON2nr4qrurfkxyOeRyprGip1nfLKF5dJY
Parameter Value
price 1000000
amount 0.01
market BTC_TMN
timestamp 1577165821400

Example:

  • curl command:

    (HMAC SHA256)
[linux]$ curl -H "PUBKEY: Xm89ak2z8cA2MjP4ywRlshyeOboAkZI9rDBNWjKu58DCiTUgrmJGfsbxCrmFcYcz" -X GET 'https://changekon.com/api/v1/order/buy?signature=1199881f4826ff4ff8e236494480a77ef8fd969cf7981ba98b41053a638435d6&timestamp=1577165476400&price=1000000&amount=0.01&market=BTC_TMN'

Terminology

Order status (status):

  • PENDING
  • FILLED
  • CANCELLED

Order side (side):

  • BUY
  • SELL

HTTP Return Codes

  • HTTP 400 return codes are used when required parameter are missing from query. for example market in a buy order.
  • HTTP 401 return codes are used for malformed requests; the issue is on the sender's side. usually for missing PUBKEY or invalid signature
  • HTTP 403 return code is used when the WAF Limit (Web Application Firewall) has been violated.
  • HTTP 404 return code is used when the requested order are not found.
  • HTTP 406 return code is used when user has not enough balance to do requested query
  • HTTP 408 return code is used when request timeout use Check server time to synchronize your time to server
  • HTTP 5XX return codes are used for internal errors; the issue is on changekon's side. It is important to NOT treat this as a failure operation; the execution status is UNKNOWN and could have been a success.
