How to create an API key for Coinbase futures?

Generate a Coinbase Futures API key with proper permissions, passphrase, and IP whitelisting for secure programmatic trading access.

Jul 22, 2025 at 08:28 pm

Understanding Coinbase Futures API Keys


An API key for Coinbase Futures allows you to interact programmatically with your futures trading account. This includes placing orders, checking balances, and retrieving market data. Unlike the spot trading API, the futures API requires specific permissions and must be generated from the correct section of your Coinbase account. Each API key is tied to your account and should be treated like a password. If compromised, it can grant unauthorized access to your funds and trading capabilities.

Navigating to the API Management Section


To begin, log in to your Coinbase account at [pro.coinbase.com](https://pro.coinbase.com). Hover over your profile icon in the top-right corner and select "Settings" from the dropdown. In the left-hand navigation menu, click on "API". This will take you to the API management dashboard. Ensure you are using a verified and secured Coinbase Pro account with futures trading enabled. If you see a banner indicating futures are not available, you must complete identity verification and apply for futures access separately.

Generating a New API Key


Once in the API section:

  • Click the blue "New API Key" button
  • Under "API Key Name", enter a descriptive label like "Futures Bot" or "Trading Script"
  • Check the box labeled "Futures Trading" — this is essential for futures functionality
  • Optionally enable "View" if you want the key to retrieve account balances and positions
  • Leave "Trade" unchecked unless your application needs to place or cancel orders
  • Set a strong Passphrase — this is required to authenticate every API request
  • Confirm your identity using 2FA (SMS or authenticator app)

    Never share your passphrase or API secret with anyone. These credentials are used to sign requests and cannot be recovered if lost.

    Configuring IP Whitelisting (Recommended)


    For added security, restrict API access to specific IP addresses:
  • In the "IP Whitelist" section, click "Add IP Address"
  • Enter the public IP of the machine or server that will use the API
  • Repeat for each trusted IP
  • Save the configuration

    Without IP whitelisting, your API key can be used from any location, increasing risk. If you're testing locally or using dynamic IPs, consider using a VPS with a static IP for production use.

    Testing the API Key with cURL


    After creation, you’ll see your API key, secret, and passphrase. Store these securely — they are only shown once. To verify the key works:
  • Open your terminal or command prompt
  • Run the following cURL command:
    curl -H "CB-ACCESS-KEY: YOUR_API_KEY" \
    -H "CB-ACCESS-SIGN: $(echo -n "GET/accounts" | openssl dgst -sha256 -hmac YOUR_API_SECRET)" \
    -H "CB-ACCESS-TIMESTAMP: $(date +%s)" \
    -H "CB-ACCESS-PASSPHRASE: YOUR_PASSPHRASE" \
    https://api.pro.coinbase.com/futures/accounts

    Replace YOUR_API_KEY, YOUR_API_SECRET, and YOUR_PASSPHRASE with your actual values. A successful response will return JSON data about your futures account. A 401 error means one of the fields is incorrect or the key lacks futures permissions.

    Common Misconfigurations and Fixes

  • If you get a "permission denied" error, ensure the key has "Futures Trading" enabled
  • If the timestamp is too far from the server time, sync your system clock using NTP
  • If the signature is invalid, double-check the HMAC-SHA256 encoding process
  • If the IP is blocked, verify the whitelisted IPs match the source of the request

    Always test API keys in a sandbox environment before using them in live trading systems. Mistakes in key configuration can lead to failed orders or unauthorized access.


    Frequently Asked Questions

    Can I use the same API key for both spot and futures trading?

    Yes, but only if you enable both "Spot Trading" and "Futures Trading" during key creation. Each permission must be explicitly checked. A key with only spot permissions will fail when accessing futures endpoints.

    What should I do if I lose my API secret?

    You cannot recover a lost API secret. You must delete the compromised key and generate a new one. Any applications using the old key will stop working until updated with the new credentials.

    Why does my API request return a 403 error even with correct credentials?

    A 403 error often means the key lacks the required permissions. Confirm that "Futures Trading" is enabled. Also check if IP whitelisting is active and whether your current IP is allowed.

    Is it safe to store API keys in environment variables?

    Yes, storing keys in environment variables is a standard practice in development. Avoid hardcoding them in scripts or committing them to version control. Use tools like .env files with proper file permissions to protect them.
