API Authentication | Secure Access to PowerTrade Trading API

Learn how to generate & manage API keys. Secure authentication for safe automated trading on PowerTrade.

All private endpoints require a valid access token.

Generate an API Key and Private Key

Create an account on the Power Trade's web application.
In the account profile menu in the top right and choose API Keys
The resulting API Key api_key and Private key private_key can be used to generate a JWT.

Generate an access token - JWT

Use the ES256 algorithm and add {client: "api"} to the payload when generating the token jwt_token.

Example in python

def generate_access_token(api_key, private_key):
    now = utils.time.time_s()
    return jwt.encode({"exp": now + 60, "iat": now,
                       "sub": api_key, "client": "api"}, private_key, algorithm="ES256")

Example in Node.js

Using jsrsasign

import rs from "jsrsasign";

const header = { alg: "ES256", typ: "JWT" };

const payload = {
  sub: api_key,
  iat: rs.KJUR.jws.IntDate.get("now"),
  exp: getUnixTime(add(Date.now(), { days: 10 })),
  client: "api",
  nonce: getUnixTime(Date.now()),
};

const headerString = JSON.stringify(header);
const payloadString = JSON.stringify(payload);

return rs.KJUR.jws.JWS.sign("ES256", headerString, payloadString, private_key);
