Embedding Restrictions

Allow inline/popup embedding only on approved domains.

Restrict website embedding

Enable this option on a form when you want to prevent arbitrary websites from framing it.

Allowed domains

Enter approved domains:

  • One per line, or
  • Separated by commas

Examples:

example.com

shop.example.com

Installation domain

The DoorFall Forms installation itself remains allowed.

Direct link

Direct standalone form links still work when embedding is restricted.

Troubleshooting

If a form works by Direct Link but not in an iframe:

  1. Open Builder.
  2. Check Restrict website embedding.
  3. Confirm the destination domain appears in Allowed domains.
  4. Save.
  5. Test again.
