HighLevel API Domain vs White-Label Domain: What's the Difference?

HighLevel has two different domain types you can customize: the white-label domain and the API domain. They serve different purposes and are not interchangeable.

White-Label Domain

Purpose: Where your clients log in to access the platform.

Example: app.youragency.com

What it controls:

• Login URL for your branded portal
• Where users access the dashboard
• The domain shown in the browser when using HighLevel

API Domain

Purpose: Used for rendering special system links.

Example: link.youragency.com

What it controls:

• Trigger links
• Review request links
• Unsubscribe links
• Other system-generated URLs

Why They're Separate

These domains serve completely different functions:

• White-label domain = User authentication and dashboard access
• API domain = System links in emails, SMS, and automations

If you only set up one, the other will still show default HighLevel URLs.

How to Set Them Up

White-Label Domain

1. Go to Agency Settings → White Label
2. Add your subdomain (e.g., app.youragency.com)
3. Add the CNAME record to your DNS (Cloudflare recommended)
4. Save and verify

API Domain

1. Go to Agency Settings → API Domain
2. Add your subdomain (e.g., link.youragency.com)
3. Add the CNAME record to your DNS
4. Save and verify

Common Mistakes

• Using the same subdomain for both — They need different subdomains
• Only setting up one — You need both for full white-labeling
• Confusing which is which — Login = white-label, Links = API
