# Filter: gk/gravityview/view/secret/allow-legacy

Whether to accept a View's previous (pre per-site-key) secret.

It is accepted by default only for Views created before this site established its per-site key, so their existing embeds keep working; Views created after that boundary use only the per-site secret. Return true to accept the previous secret for every View during a wider transition window, or false to require the per-site secret everywhere.

## Parameters

| Name | Type | Description |
|------|------|-------------|
| $allow_legacy | `bool` | Whether to accept the previous secret. Default: true only for pre-key Views. |
| $view | `\View` | The View being validated. |
