Binance API Key Invalid Permissions Fix 2026 (Step-by-Step)

Getting the "Invalid API Key Permissions" error when connecting Binance to your trading bot? You're not alone. This is the #1 error traders face when setting up automated trading. This guide shows you exactly how to fix it in 2026.

Why This Error Happens

The "Invalid Permissions" error occurs when:

• API key permissions are incorrectly configured
• Required permissions are not enabled
• IP restrictions are blocking access
• API key was created before enabling 2FA

Quick Fix (5 Minutes)

Step 1: Delete Your Current API Key

IMPORTANT: Before creating a new key, delete the broken one.

Log into Binance

Go to Profile Icon → API Management

Find your API key

Click Delete (trash icon)

Confirm deletion with 2FA code

Step 2: Create New API Key with Correct Settings

Click Create API button

Choose System Generated (NOT Third Party)

Enter label: "3Commas Trading Bot 2026"

Complete 2FA verification

Step 3: Configure Permissions Correctly

✅ ENABLE THESE:

• ✅ Enable Reading (MUST be checked)
• ✅ Enable Spot & Margin Trading (MUST be checked)

❌ NEVER ENABLE THESE:

• ❌ Enable Withdrawals (SECURITY RISK - leave unchecked)
• ❌ Enable Internal Transfer (Not needed)
• ❌ Enable Futures (Only if using futures bots)

Screenshot Reference:

[✓] Enable Reading
[✓] Enable Spot & Margin Trading
[ ] Enable Withdrawals  ← NEVER CHECK THIS
[ ] Enable Internal Transfer
[ ] Enable Futures

Step 4: Configure IP Restrictions (Recommended)

For maximum security, restrict API access to 3Commas IPs:

Option A: Restrict to Trusted IPs (Recommended)

Select Restrict access to trusted IPs only

Add these 3Commas IP addresses:

- 54.89.227.44

- 34.230.69.31

- 52.7.22.163

- 18.209.181.105

Option B: Unrestricted (Less Secure)

Select Unrestricted if you have dynamic IP

Only use this temporarily for testing

Step 5: Save and Copy API Keys

Click Create button

IMMEDIATELY COPY:

- API Key (long string)

- Secret Key (shown ONLY ONCE)

Store in password manager

Click Done

Step 6: Connect to 3Commas

Open 3Commas

Go to My Exchanges

Click + Connect Exchange

Select Binance

Paste API Key

Paste Secret Key

Name connection: "Binance Main 2026"

Click Connect
