🔎 FlashEx — API Connection Verification Guide

📌 Context

After completing API authorization with OKX, users should verify if the connection is successful and data is properly synced.

👉 If you have not yet configured OKX API access, please refer to: [API Setup Guide]

---

✅ Step-by-Step Connection Checks

1️⃣ Check API Connection Status

• Open FlashEx App

• Go to Main menu → Settings (API Management)

• Confirm that the status shows “Connected to OKX” ✅ If connected, API read access is working.

---

2️⃣ Check Balance Sync

• On the FlashEx home screen (bottom left), confirm:

  • Whether your USDT balance from OKX is displayed

  • If balance shows 0, but you have assets on OKX:

    • Check whether funds are in the Futures Account

    • FlashEx only reads USDT balance from the Futures Account, not from Funding or Spot

✅ If your balance appears correctly, the API is connected successfully.

---

3️⃣ Test Order Execution

Try placing a small test order:

• Select a supported contract (e.g., BTC/USDT)

• Choose a Market or Limit Order

• Enter size, then click Long or Short

✅ If the order is placed and an auto take-profit order is generated, API connection & trading permission are both functioning.

---

❌ If API Connection Fails, Please Check:

• Whether you're using the recommended OAuth (automatic) authorization

• Whether your API permission includes both “read” and “trade” (withdrawal not required)

• If the API key has been deleted, expired, or disabled in OKX backend

• If there are any network issues or outdated FlashEx App versions in use

❗ FlashEx — “No Balance” Troubleshooting

📍 Problem:

FlashEx successfully logged in, but the bottom of the home screen shows: “Available Balance: 0”

👉 If you have not yet configured OKX API access, please refer to: [API Setup Guide]

---

✅ Step-by-Step Troubleshooting

① Ensure API Authorization is Completed

• ✅ Login to FlashEx → Check API status in settings shows “Connected”

• ✅ Ensure OKX is the authorized exchange, with both “read” and “trade” permissions 👉 If not authorized or expired, re-bind via OAuth (recommended)

---

② Ensure Funds are in the OKX Futures Account

FlashEx reads data only from Futures Account, not Spot or Funding.

✅ Steps:

• Open OKX App

• Go to Assets → Account Types: Funding / Spot / Futures

• If funds are not in the Futures Account:

  Tap Transfer → From: Funding → To: Futures → Enter amount → Confirm

📌 FlashEx supports: USDT in Futures Account

---

③ Ensure You Are Using a Supported Contract

FlashEx only supports USDT-margined perpetual futures on OKX. If your funds are in spot/other accounts, balance won't show, and you can’t place orders.

---

🚨 Additional Notes:

• 📌 FlashEx never holds your funds — your assets remain entirely in your own OKX account

• ⏱ If you've just transferred funds, refresh or re-enter the app to update

• 📲 Make sure you're using the latest version of the FlashEx App
