Merchant API

Integrate GameHub into your player-facing site.

Base URL

https://your-domain.com/api/public/v1

Authentication

Every request is a JSON POST with these top-level fields:

operator_code — your op_code
request_time — Unix seconds (string)
sign — md5(operator_code + request_time + method + secret_key)

Method strings: launchgame, gamelist, playerbalance, wagerlist.

Node sample

import { createHash } from "crypto";

const OP = "YOUR_OP_CODE";
const SECRET = "YOUR_SECRET_KEY";
const t = Math.floor(Date.now()/1000).toString();

function sign(method) {
  return createHash("md5").update(OP + t + method + SECRET).digest("hex");
}

const res = await fetch("https://your-domain.com/api/public/v1/game/launch", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    operator_code: OP,
    request_time: t,
    sign: sign("launchgame"),
    member_account: "player123",
    product_code: "PR-SLOT",
    game_code: "moreturkeyv10000",
    language: "en",
  }),
});
console.log(await res.json());

PHP sample

$op = "YOUR_OP_CODE";
$secret = "YOUR_SECRET_KEY";
$t = (string) time();
$sign = md5($op . $t . "launchgame" . $secret);
$body = json_encode(compact("op","t","sign") + [
  "operator_code" => $op, "request_time" => $t, "sign" => $sign,
  "member_account" => "player123", "product_code" => "PR-SLOT",
]);
$ch = curl_init("https://your-domain.com/api/public/v1/game/launch");
curl_setopt_array($ch, [CURLOPT_POST=>1, CURLOPT_POSTFIELDS=>$body,
  CURLOPT_HTTPHEADER=>["Content-Type: application/json"], CURLOPT_RETURNTRANSFER=>1]);
echo curl_exec($ch);

Wallet flow

When a player launches a game, GameHub relays wallet operations to your player's balance automatically. You do not implement any callback — bets and wins settle in real time inside GameHub against your merchant credit.
