Prerequisites

Before you begin, make sure you have:

• Verified MEXC account - Identity verification (KYC) completed
• 2FA enabled on MEXC - Required for API key creation
• SignalBee account - Ready to connect an exchange
• Password manager - For storing your API credentials securely

Security Note: MEXC requires 2FA (two-factor authentication) to create API keys. If you haven't enabled 2FA yet, go to Profile → Security in your MEXC account.

Creating Your API Key

Follow these steps to create an API key on MEXC:

Step 1: Log In to MEXC

1. Go to www.mexc.com
2. Log in with your email and password
3. Complete 2FA verification if prompted

Step 2: Navigate to API Management

1. Click your profile icon in the top-right corner
2. Select API Management from the dropdown menu
3. You'll see a list of your existing API keys (if any)

Step 3: Create a New API Key

1. Click the Create API button
2. You'll be presented with the API configuration screen

Step 4: Enter a Description

1. Enter a descriptive note: SignalBee Trading
2. A clear label helps you identify this key's purpose later

Tip: Use specific labels like "SignalBee-Spot" or "SignalBee-Main" if you plan to create multiple keys for different purposes.

Step 5: Configure Permissions

1. Check the permission boxes as described in the Configuring Permissions section below
2. Enable Read and Spot Trade permissions
3. Never enable the Withdrawal permission

Step 6: Complete Security Verification

1. Enter your 2FA code from your authenticator app
2. Complete email verification if prompted
3. Click Confirm to create your key
4. Wait for the system to generate your credentials

Step 7: Copy Your Keys IMMEDIATELY

After creation, your credentials will be displayed:

• Access Key (API Key) - Can be viewed later in your API Management page
• Secret Key - Shown only ONCE - Copy it immediately!

Warning: If you navigate away without copying your Secret Key, you'll need to delete this API key and create a new one. There is no way to recover a Secret Key.

Save both keys in your password manager now before proceeding.

Configuring Permissions

MEXC has a straightforward permission system. This is critical for security.

Required Permissions

Never Enable These Permissions

Security Note: Even if your API key is somehow compromised, funds cannot be withdrawn without withdrawal permission enabled. This is your most important security protection.

Simple Two-Credential Setup

MEXC uses a simple credential model similar to Binance:

This makes MEXC one of the simpler exchanges to configure.

IP Whitelist Configuration

IP whitelisting restricts your API key to only work from specific IP addresses. This is optional but adds a strong security layer.

Why Use IP Whitelisting?

Even if your API key is somehow exposed, it won't work from unauthorized IP addresses.

SignalBee Server IP Addresses

Note: Contact support@signalbee.trade to request SignalBee's current production IP addresses for whitelisting. We maintain static IPs specifically for exchange API calls and will notify you before any infrastructure changes.

How to Configure IP Whitelisting

1. In API Management, find your SignalBee API key
2. Click Edit next to the key
3. Enable IP Address Restriction
4. Enter each SignalBee IP address provided by support
5. Click Save
6. Complete 2FA verification if prompted

If You Skip IP Whitelisting

If you choose not to use IP whitelisting:

1. Leave IP restrictions disabled
2. Understand this is less secure but still safe if withdrawals are disabled
3. Your other security measures (no withdrawal permission) still protect your funds

Adding to SignalBee

Now connect your MEXC API key to SignalBee:

Step 1: Go to Exchanges Page

1. Log in to your SignalBee account
2. Navigate to Exchanges in the main menu

Step 2: Add New Exchange

1. Click the Add Exchange button
2. Select MEXC from the exchange list

Step 3: Enter Your Credentials

MEXC uses a simple two-value API system:

1. API Key - Paste your MEXC Access Key
2. Secret Key - Paste your MEXC Secret Key
3. Label (optional) - Enter a name like "MEXC Main Account"

Note: MEXC requires only 2 credentials (Access Key + Secret Key). This is simpler than exchanges like OKX or KuCoin that require an additional passphrase.

Step 4: Test the Connection

1. Click Save and Test Connection
2. Wait for SignalBee to verify your credentials
3. Look for the success message

Step 5: Verify Your Setup

After successful connection:

1. Your MEXC balances should appear in SignalBee
2. Check that your expected assets are listed
3. Balances confirm the Read permission is working

Tip: If balances don't appear, verify that Read permission is enabled on your API key.

MEXC-Specific Considerations

Ticker Format

MEXC uses concatenated uppercase ticker symbols with no separator. SignalBee converts automatically:

No action needed! Your webhook symbols work directly with MEXC - SignalBee handles the conversion automatically.

Supported Order Types

MEXC spot trading supports the following order types:

Note: If your trading strategy requires stop-loss or take-profit orders as separate order types, these must be managed at the strategy level rather than as native exchange orders.

Wide Altcoin Selection

One of MEXC's key differentiators is its extensive listing of newer and smaller-cap altcoins:

• Many tokens listed on MEXC may not be available on larger exchanges
• MEXC is often among the first to list new projects
• Check pair availability before setting up signals for lesser-known tokens
• Liquidity varies significantly by trading pair

Tip: For newer or smaller altcoins, always verify the trading pair exists on MEXC before configuring your signals.

Zero-Fee Promotions

MEXC frequently offers promotional periods with 0% maker and 0% taker fees:

• Check MEXC's current fee schedule for active promotions
• Promotional fees may apply to specific trading pairs
• Standard fees apply when promotions are not active

Tip: Check MEXC's fee schedule for the most current rates and any active zero-fee promotions.

Authentication

MEXC uses standard HMAC-SHA256 authentication, similar to Binance:

What this means for you:

• SignalBee handles this automatically - no action required
• Your credentials work exactly like other exchanges
• Time synchronization is critical (5-second validation window)
• SignalBee handles time sync automatically

Note: You don't need to understand the technical details. Just provide your Access Key and Secret Key, and SignalBee handles the rest.

Minimum Order Sizes

MEXC enforces minimum order values. Orders below these minimums will be rejected:

Tip: Check MEXC's trading rules for current minimum order sizes for specific pairs.

API Rate Limits

• MEXC enforces rate limits on API requests
• SignalBee handles rate limiting automatically
• If you see rate limit errors (-1003), reduce your signal frequency or check for duplicate webhooks

No Testnet Available

Important: Unlike some exchanges (like Binance), MEXC does not offer a public testnet for spot trading.

Tip: Start with small order sizes (e.g., $10-20) when first testing your SignalBee integration with MEXC.

Troubleshooting

Common MEXC-specific errors and solutions:

Connection Test Fails?

If your connection test fails in SignalBee:

1. Double-check both keys - Copy-paste errors are the most common issue
2. Verify permissions - Ensure Read and Spot Trade permissions are enabled
3. Check IP whitelist - Disable IP restriction temporarily to test
4. Wait a few minutes - New API keys may take 1-2 minutes to propagate
5. Check MEXC status - Verify MEXC is not under maintenance

For persistent issues, see our Error Codes Reference or contact support@signalbee.trade.

Security Best Practices

Follow this checklist to keep your MEXC account secure:

MEXC Account Security

• Enable 2FA with Google Authenticator - more secure than SMS
• Use a unique, strong password for MEXC (not reused from other sites)
• Enable email notifications for account activity
• Review login history regularly for unauthorized access

API Key Security

• Create a dedicated API key just for SignalBee - don't reuse keys across services
• Never enable withdrawal permission - SignalBee never needs it
• Consider IP whitelisting for maximum security
• Never share your Secret Key via email, chat, or screenshots
• Store keys in a password manager (1Password, Bitwarden, etc.)

Ongoing Security

• Review your API keys periodically in MEXC - delete any you don't recognize
• Rotate API keys every 90 days as a security habit
• Monitor trade history on MEXC for any unauthorized activity

Security Note: Even with all these precautions, the most important protection is never enabling withdrawal permission. Without this permission, your funds cannot be moved off the exchange even if everything else is compromised.
