Domain Whitelisting: Control Where Your Flipbook Can Be Embedded

Why Domain Whitelisting Matters for Your Flipbooks

You've spent hours creating a polished flipbook — a product catalog, a sales proposal, or a training manual. You embed it on your website, and everything looks great. But then you discover someone has copied your embed code and placed your flipbook on a completely unrelated site.

Domain whitelisting prevents exactly this. It lets you define a list of approved websites where your flipbook is allowed to load. If someone tries to embed your content on a domain that isn't on your list, the flipbook simply won't render.

This isn't about hiding content behind a login or adding a password. It's about controlling where your content appears — a layer of protection that works silently in the background every time your embed code is used.

When You Need Domain Whitelisting

Not every flipbook needs domain restrictions, but there are several situations where whitelisting becomes essential:

• Branded content on partner sites — You share an embed code with a partner, but you don't want that same code reused on other sites without your knowledge.
• Paid or gated content — If you sell documents or offer premium flipbooks, restricting embeds ensures only paying clients can display them.
• Sales proposals and client materials — When you send a sales proposal embedded on a client's internal portal, whitelisting keeps it from appearing anywhere else.
• Compliance and legal requirements — Some industries require that sensitive documents only appear on approved, secured domains.
• Brand reputation — You want full control over the context in which your content is displayed. A professional catalog shouldn't show up on a spam site.

How to Set Up Domain Whitelisting in FlipLink

Setting up domain restrictions in FlipLink takes just a few steps. Here's how to do it:

Step 1: Open Your Flipbook Settings

Log in to your FlipLink dashboard at go.fliplink.me and navigate to the flipbook you want to protect. Click on the settings or security tab for that flipbook.

Step 2: Find the Domain Whitelisting Section

Under the privacy and access control settings, look for the domain whitelisting option. This is where you'll manage which websites are authorized to embed your content.

Step 3: Add Your Approved Domains

Enter the domains where you want the flipbook to be embeddable. You can add:

• A single domain like yoursite.com
• Multiple domains separated by commas
• Subdomains like blog.yoursite.com or docs.yoursite.com
• Wildcard subdomains using *.yoursite.com to cover all subdomains at once

Step 4: Save and Test

Save your settings and test the embed on an approved domain to confirm it loads correctly. Then try loading it on an unapproved domain to verify it's blocked.

Whitelisting Scenarios at a Glance

Choose the configuration that matches your distribution strategy. You can always update the whitelist later as your needs change.

What Happens on an Unauthorized Domain

When someone copies your embed code and places it on a domain that isn't whitelisted, the flipbook will not load. Instead of your interactive 3D page-flip experience, visitors on that unauthorized site will see either a blank space or a brief message indicating the content is restricted.

This means:

• Your content stays protected — No one can hijack your flipbook and display it out of context.
• No data leakage — Analytics and lead capture data won't be muddied by traffic from unauthorized sources.
• Embed codes remain safe to share — You can hand out embed codes to partners without worrying about misuse.

The restriction happens at load time, so there's no impact on your approved embeds. Visitors on whitelisted domains won't notice any difference — the flipbook loads instantly as expected.

Combining Domain Whitelisting with Other Security Features

Domain whitelisting works best as part of a layered security approach. FlipLink offers several features that complement it:

Password Protection

Password protection adds a viewer-level gate. Even if someone accesses the flipbook on an approved domain, they still need the correct password to view it. This is ideal for confidential client documents or internal training materials.

Clickable Image Embeds

If you want to show a preview without exposing the full flipbook, use a clickable image embed. Visitors see a static thumbnail that links to the full flipbook on your domain — keeping the actual interactive content behind your whitelisted environment.

Lead Capture

Combine domain whitelisting with lead capture forms so you know exactly who is viewing your content and from which approved source. This is particularly useful for gated marketing materials.

Access Control Settings

FlipLink's privacy and access control settings give you granular options beyond just domain whitelisting. You can control download permissions, print restrictions, and more — all from the same settings panel.

Here's how these features layer together:

Best Practices for Domain Whitelisting

A few tips to get the most out of this feature:

• Start restrictive, then expand. It's easier to add domains later than to clean up after unauthorized embeds spread.
• Use wildcards carefully. A wildcard like *.yoursite.com is convenient but covers every subdomain, including any you might not control.
• Audit your whitelist regularly. Remove domains you no longer work with, especially after ending partnerships or sunsetting microsites.
• Combine with analytics. Check your flipbook analytics to see if embed traffic matches your expectations. Unexpected traffic sources could indicate your embed code has been shared.
• Document your whitelist. Keep a record of which flipbooks are whitelisted for which domains, especially if multiple team members manage content.
