Keep Your API Key Safe (It's Easier Than You Think)

Your MailerLite API key is valuable, but protecting it doesn't require a cybersecurity degree. Here are the four golden rules:

• Store it securely: Save your API key in a password manager or secure document, never in plain text files
• Don't share publicly: Never post your API key in forums, code repositories, or public documentation
• Use environment variables: If you're working with developers, ask them to store the key in environment variables
• Monitor usage: Check your MailerLite account regularly for any unusual activity or unauthorized access

Quick test: After setting up your integration, send yourself a test email to make sure everything's working correctly before going live.

The Professional Way to Collect Client Credentials

"Hey, I need your MailerLite API key to set up your e-commerce integration."
"Um, how do I get that? Can you just do it for me?"
"Well, I'd need access to your account..."

Sound familiar? This awkward dance happens countless times between service providers and their clients. What if there was a better way?

Imagine sending your client a simple, secure link where they can generate their MailerLite API key themselves and share it with you safely. No more screen sharing sessions, no more "I forgot my password" delays, and no more security concerns about account access.
