If you're worried that your MailChimp API key has been compromised, or you no longer use the integration, you can disable that API key. Just follow the steps below:
- Sign into your MailChimp account, and click your profile name to expand the Account Panel, and choose 'Account.'
- Click the 'Extras' menu, and choose 'API keys.'
- Find the API key you want to disable, and click the 'Disable' link in the 'Status' column for that API key.
