How to Connect Binance to 3Commas: Step-by-Step API Guide

Connecting your Binance account to 3Commas unlocks powerful automated trading features. This guide walks you through the process step by step.

Prerequisites

Before starting, ensure you have:

• A verified Binance account
• A 3Commas account (free trial available)
• 2FA enabled on both accounts

Step 1: Create API Keys on Binance

Log into your Binance account

Navigate to Profile → API Management

Click Create API

Choose System Generated for maximum compatibility

Enter a label (e.g., "3Commas Trading Bot")

Complete security verification

Step 2: Configure API Permissions

Enable these permissions for your API key:

• ✅ Enable Reading
• ✅ Enable Spot & Margin Trading
• ❌ Enable Withdrawals (NEVER enable this)
• ❌ Enable Futures (unless using futures bots)

Security Note: Never enable withdrawal permissions. 3Commas only needs trading access.

Step 3: Restrict IP Access (Recommended)

For enhanced security:

Select Restrict access to trusted IPs only

Add 3Commas IP addresses (found in their documentation)

Save changes

Step 4: Copy Your API Keys

After creation, you'll see:

• API Key: A long string of characters
• Secret Key: Only shown once—copy it immediately!

Store these securely. If you lose the secret key, you'll need to create new keys.

Step 5: Add Keys to 3Commas

Log into 3Commas

Go to My Exchanges

Click + New Exchange

Select Binance

Paste your API Key and Secret Key

Name your connection

Click Connect

Step 6: Verify Connection

3Commas will verify your connection by:

• Checking API permissions
• Fetching your balance
• Testing order capabilities

If successful, you'll see your Binance balance in 3Commas.

Troubleshooting Common Issues

"Invalid API Key"

• Double-check for extra spaces when copying
• Ensure the API key is active on Binance
• Verify you're using the correct key pair

"Permission Denied"

• Enable Spot & Margin Trading permission
• Wait a few minutes after changing permissions
• Try creating new API keys

"IP Restriction Error"

• Add 3Commas IPs to your whitelist
• Or temporarily disable IP restrictions to test

Security Best Practices

Use unique API keys for each service

Never share your secret key

Enable IP restrictions when possible

Regularly audit your API keys

Delete unused API keys

Monitor for unauthorized activity
