API Keys 🔑

​

Creating a key

1. Go to API Keys in your dashboard
2. Click Create Key and give it a name (like production or staging)
3. Copy the key — it’ll start with mfly_live_

export MAILOFLY_API_KEY=mfly_live_your_key_here

​

Using it in your app

Authorization: Bearer mfly_live_your_key_here

import { Mailofly } from "@mailofly/node";

const client = new Mailofly({ apiKey: process.env.MAILOFLY_API_KEY! });

curl https://api.mailofly.com/accounts \
  -H "Authorization: Bearer $MAILOFLY_API_KEY"

​

Tips for keeping your key safe

• 🔑 One key per service — if a key leaks, you only have to rotate that one
• 🚫 Never commit it to git — seriously, even “just for testing”
• ⏰ Use short-lived keys for contractors, staging, or one-off scripts
• 🔄 Rotate regularly — especially if you think it might have been exposed
