# fswa\_notification\_inline\_send

Decide whether a delivery's notifications are sent at the end of the same request or left for cron. On by default for synchronous webhooks, off for queued ones.

/ Signature

```
apply_filters( 'fswa_notification_inline_send', $inline, $ctx )
```

/ When it fires

Right after a rule has queued at least one notification for a delivery. A queued delivery already runs under cron, so its notifications go out on the next tick; a synchronous delivery ran inline with no cron involved, and without this its alerts would wait for a cron that may never run (`DISABLE_WP_CRON` on a site that only uses synchronous webhooks). The inline flush happens after the response is produced, and the cron event stays booked as a fallback either way.

/ Parameters

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| $inline | param | bool | yes | The default: \`true\` when the webhook that produced the event is synchronous, \`false\` when it was queued. |
| $ctx | param | array | yes | The delivery context handed to \`fswa\_delivery\_event\`: \`event\`, \`webhook\` (with \`is\_synchronous\`), \`trigger\`, \`attempt\`, \`http\_code\`, \`error\_message\`, \`payload\`, … |

/ Returns

`bool` \`true\` to flush on \`shutdown\` of the current request, \`false\` to book the one-shot cron event and spawn WP-Cron.

/ Examples

Keep synchronous webhooks fast: always leave sends to cron

```
add_filter( 'fswa_notification_inline_send', '__return_false' );
```

Send permanently-failed alerts inline even for queued deliveries

```
add_filter( 'fswa_notification_inline_send', function ( bool $inline, array $ctx ) {
    return $ctx['event'] === 'permanently_failed' ? true : $inline;
}, 10, 2 );
```
