## What You Can Do

With the Resend Integration, your app can:
- Send automated transactional emails
- Notify users of important events (signups, job completions, etc.)
- Integrate email sending into AI workflows
- Use dynamic variables in your message body (e.g. user name, order ID)

1. Go to [Resend](https://resend.com/).
2. Log in or create a free account.
3. Navigate to **API Keys** from the dashboard sidebar.
4. Click **Create API Key**, give it a name (e.g. “AI Builder”), and copy it.
   - Example: `re_xxxxxxxxxxxxxxxxxxxxxxxxxxxx`

## Step 2: Configure the Integration in Your App

1. Open your app in the **AI Builder**.
2. Click the **Settings** gear icon and navigate to the **Integrations** tab.
3. Find and enable the **Resend** integration.
