Understanding API Keys on OKX

To interact with the OKX exchange programmatically, especially for building or running trading bots, you need to obtain an API key. An API (Application Programming Interface) key acts as a secure token that allows your bot to communicate with the exchange's servers. On OKX, these keys come with customizable permissions such as read-only access, trade execution, or withdrawal capabilities. It’s crucial to understand how these permissions affect your account security and trading operations.

Logging into Your OKX Account

Before generating an API key, ensure you're logged into your OKX account securely. Navigate to the official website and enter your credentials. Once logged in, verify that two-factor authentication (2FA) is enabled — this adds an extra layer of protection for your account and any associated API keys.

• Make sure you are using a trusted device and network.
• Confirm your email and phone number are up to date for recovery purposes.
• Ensure no suspicious activity has occurred on your account recently.

Navigating to the API Management Section

After logging in, locate the API management section within your OKX account settings. This can typically be found under the "Trade" or "Funds" tab in the main dashboard. Clicking into this section will reveal options for creating, managing, and deleting API keys.

• Go to the top-right corner and click on your profile icon.
• Select “API Settings” or a similar option from the dropdown menu.
• You'll be redirected to the API management page where all existing keys are listed.

This interface allows you to monitor active connections and revoke access if needed.

Creating a New API Key

Once inside the API management area, proceed to generate a new API key tailored for your trading bot. Click the “Create API Key” button, and you’ll be prompted to fill in specific details:

• Choose a label for easy identification (e.g., “TradingBot_v1”).
• Select the appropriate permissions: enable “Spot Trading” or “Futures Trading” depending on your bot's functionality.
• Optionally enable withdrawal permissions, but it’s strongly advised to avoid this unless absolutely necessary for your use case.
• Set IP binding to restrict usage of the API key to specific machines or servers.

After configuring these options, click “Confirm” to finalize the creation process.

Securing and Storing Your API Credentials

Upon successful generation, OKX will display your API key and secret key. These are critical pieces of information that should be handled with utmost care.

• Copy both the API key and secret key immediately; they won’t be shown again after you close the window.
• Store them in a secure password manager or encrypted file.
• Avoid sharing them or hardcoding them directly into public repositories or scripts.
• Consider setting up alerts or monitoring tools to detect unauthorized API usage.

Failure to protect these keys may lead to unauthorized trades or fund withdrawals.

Testing Your API Connection

With your keys secured, the next step is to test the connection between your trading bot and OKX’s API. Most bots or custom scripts require pasting the API key and secret key into designated fields.

• Launch your trading bot software or script.
• Locate the API configuration section.
• Paste the API key and secret key into their respective fields.
• Save the configuration and initiate a test request (e.g., fetching account balance or market data).

If the response returns valid data without errors, your API integration is working correctly.

Managing and Revoking API Keys

As part of good security hygiene, regularly review your active API keys. If a key is no longer in use or was compromised, it should be revoked immediately.

• Return to the API management page.
• Locate the key you wish to delete.
• Click the “Revoke” or “Delete” button next to it.
• Confirm the action when prompted.

Revoked keys lose all access instantly, so make sure to update your bot configurations accordingly if switching keys.

Frequently Asked Questions

Can I use the same API key across multiple trading bots?

Yes, technically you can use the same API key across multiple bots, but it's not recommended due to security concerns. Using separate keys for each bot allows better tracking and isolation of potential breaches.

What permissions do I need for my trading bot on OKX?

At minimum, your bot needs read and trade permissions for spot or futures markets depending on your strategy. Avoid enabling withdrawal permissions unless explicitly required.

Is it safe to share my OKX API key with third-party services?

Only share your API key with trusted platforms or developers. Always ensure that the service uses encryption and does not store keys in plaintext. Limit permissions wherever possible.

How often should I rotate my OKX API keys?

It's advisable to rotate API keys every 3–6 months or immediately after any suspected exposure. Regular rotation enhances account security and reduces the risk of unauthorized access.
