How to Create and Set Up OKX API Key (OKX Referral Code: SUPER20OFF)

Setting up your OKX API connection doesn't have to be complicated. Whether you're looking to automate your trading strategy or connect with third-party platforms, this guide shows you two straightforward methods: the quick OAuth setup and the traditional manual configuration. Both approaches give you full control over your trading permissions while keeping your account secure.

Why Connect Your OKX API?

Connecting your OKX account through API opens up possibilities for automated trading, portfolio management, and integration with advanced trading tools. The process is designed with security in mind—you control exactly what permissions to grant, and your login credentials stay private.

OKX offers two connection methods to fit different use cases. The Fast API uses modern OAuth 2.0 authentication for instant setup, while the manual method gives you granular control over each configuration step.

Method 1: OKX Fast API Connection

The Fast API method uses OAuth 2.0 technology, which means you authorize access through OKX's secure login page without sharing your API credentials with third parties.

Step 1: Configure Your Trading Settings

Before connecting, set up your futures trading preferences:

• Navigate to Trade > Futures and click the settings icon

• Set Account mode to "Single-currency margin"

• Set Position mode to "One-way mode"

For futures trading specifically, isolated margin mode offers better risk management by limiting potential losses to the margin allocated for each position.

Step 2: Initiate the Connection

• Log in to your trading platform (like Bitsgap)

• Go to My Exchanges and click [Add new exchange]

• Select OKX from the exchange list

• Choose Fast Connect and click [Connect]

Step 3: Authorize Access

You'll be redirected to OKX's official website:

• Enter your OKX credentials and log in

• Review the permissions being requested

• Authorize the connection

The permissions allow trading operations but never grant access to your personal information or account credentials. Your password and sensitive data remain completely private.

Step 4: Verify the Connection

After authorization, you'll return to your trading platform automatically. Check that:

• OKX appears in My Exchanges with Connected status

• Your trading balance displays correctly

The setup is complete and ready for trading.

Method 2: Manual API Configuration

Manual configuration gives you direct control over API key creation and permissions. This method is ideal if you want to customize settings or prefer traditional API key management.

Step 1: Access OKX API Settings

• Log in to your OKX account

• Navigate to your profile settings

• Go to API section

Step 2: Create Your API Key

• Click [Create V5 API Key]

• Select Linking third-party apps as the purpose

• Choose your platform (such as Bitsgap) from the list

Step 3: Configure Permissions

• Create a descriptive label for your API key

• Set a Passphrase (save this securely—you'll need it later)

• Enable these permissions:

  • Read: On (view account and order data)

  • Trade: On (place and cancel orders)

Complete the security verification process when prompted.

Step 4: Save Your Credentials

After creation, OKX displays three crucial pieces of information:

• API Key

• Secret Key

• Passphrase (the one you just created)

Copy and store these securely. The Secret Key is only shown once.

Step 5: Connect to Your Platform

• Return to your trading platform

• Go to My Exchanges and click [Add new exchange]

• Select OKX and choose manual connection

• Enter your API Key, Secret Key, and Passphrase

• Click [Connect]

Step 6: Confirm the Setup

Verify that OKX appears in your exchange list with:

• Connected status indicator

• Visible trading balance

• Accessible trading pairs

Choosing Between Fast API and Manual Setup

Fast API works best when:

• You want the quickest setup process

• You're comfortable with OAuth authorization

• You're using a platform that supports Fast Connect

Manual configuration is better if:

• You need custom permission settings

• You prefer traditional API key management

• You want to create multiple keys for different purposes

Both methods are equally secure when you follow proper key management practices.

Security Best Practices

Regardless of which method you choose:

• Never share your API keys or passphrase with anyone

• Use unique passphrases for each API key

• Review and revoke unused API keys regularly

• Enable IP whitelisting when available for added security

• Store credentials in a secure password manager

Troubleshooting Common Issues

Connection shows as disconnected:

• Verify all credentials are entered correctly

• Check that required permissions are enabled

• Ensure your API key hasn't expired

Trading balance doesn't display:

• Confirm Read permission is enabled

• Wait a few moments for data to sync

• Refresh the page or reconnect

Orders fail to execute:

• Check that Trade permission is enabled

• Verify your account has sufficient balance

• Ensure the trading pair is available
