There are several best practices to keep your API keys secure in the context of email marketing:
Use Environment Variables: Store API keys in environment variables instead of hardcoding them in your application. This reduces the risk of accidental exposure. Limit Permissions: Use the principle of least privilege. Assign only the necessary permissions to each API key to minimize potential damage if a key is compromised. Rotate Keys Regularly: Regularly update and rotate your API keys to reduce the risk of long-term exposure. This practice ensures that even if a key is compromised, its usefulness is limited. Monitor Usage: Keep an eye on the usage of your API keys. Use monitoring tools to detect any unusual activity, which can be an indicator of a compromised key. Use Secure Storage Solutions: Store API keys in secure vaults or password managers that offer encryption. Avoid storing them in plain text.
