# fswa\_can\_publish\_build

Allows or refuses publishing a build to wpwebhooks.org from this site.

/ Signature

```

/ When it fires

Fires when an author tries to publish a build, after the built-in checks: WordPress Playground sandboxes and sites whose address is not reachable from the internet are refused before this filter runs.

/ Parameters

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| $allowed | param | bool|string | yes | \`true\` to allow, or a string — the reason shown to the author when publishing is refused. Default: \`true\`. |

/ Returns

`bool|string` \`true\` to allow publishing, or the refusal reason.

/ Examples

Block publishing from staging

```
add_filter( 'fswa_can_publish_build', function ( $allowed ) {
    if ( wp_get_environment_type() !== 'production' ) {
        return 'Publish builds from the production site.';
    }
    return $allowed;
} );
```
