• Store it securely - Use a password manager or your app's secure environment variables
• Regenerate if compromised - If you suspect your key has been exposed, generate a new one immediately
• Monitor usage regularly - Check your Lemlist account for any unusual activity or API calls

Quick Test: Once you've got your API key, try making a simple test call to verify it's working. Most integration platforms have a "test connection" feature that makes this super easy!
