When integrating with stablecoin services, securely managing your API keys is critical. We’ll help you create and safely store credentials for:
  • Coinbase Commerce
  • Stripe
  • Your Wallet or Smart Contract
Using environment variables keeps sensitive keys out of your source code and version control systems, such as Git.

​
🛡 Storing API Keys Securely

Set your keys in your local environment or a secure .env file: 

# Coinbase Commerce
export COINBASE_API_KEY=your_coinbase_api_key_here

# Stripe
export STRIPE_API_KEY=your_stripe_api_key_here

# On-Chain Wallet or Contract (if applicable)
export WALLET_PRIVATE_KEY=your_private_key_here
If you’re using a ‘.env’ file, the format is the same: 
COINBASE_API_KEY=your_coinbase_api_key_here
STRIPE_API_KEY=your_stripe_api_key_here
WALLET_PRIVATE_KEY=your_private_key_here
Then load your environment variables into your app securely at runtime. Tip: Never hardcode API keys directly into your JavaScript, React, or server files. :::

Key Management Best Practices

  • Rotate your API keys periodically.
  • Limit API key permissions to only what is needed.
  • Use different keys for development, staging, and production environments.
