Slack notifications not working, unable to create legacy incoming webhook

[nathan-io]

• Slack Notification Channel Version: 2.4.0
• Laravel Version: 9.5.1
• PHP Version: 8.1
• Database Driver & Version:

Description:

I see that to() is not currently supported as noted in #54 .

We're not using to(), as the channel is configured within the Slack App settings. In a greenfield project, we're still unable to send Slack notifications.

There doesn't appear to be a way to even create the legacy Incoming Webhooks anymore, and Slack's current webhook docs list creating a Slack App as the first step.

On the "Custom Integrations" area of the workspace admin dashboard, there's a warning:

We recommend replacing your custom integrations with Slack apps, which have more features and use the latest APIs.

In the Slack workspaces I have admin permissions on, there's no option to even create a custom integration. You must create a Slack App.

Steps To Reproduce:

Create a Slack App and an incoming webhook on that app. Add the webhook URI in .env and attempt to send a notification to Slack.

Our current implementation within a Notification class looks like:

  // ...
    public function via($notifiable)
    {
        return ['slack'];
    }

    public function routeNotificationForSlack($notification)
    {
        return config('app.slack_webhook_url');
    }

    public function toSlack($notifiable)
    {
        $tags = json_encode($this->tags);
        $callLink = url('/nova/resources/calls/' . $this->callId);

        return (new SlackMessage)
            ->success()
            ->content('Applied Tags to Call')
            ->attachment(function ($attachment) use ($tags, $callLink) {
                $attachment->title('Call Id ' . $this->callId, $callLink)
                    ->fields([
                        'Caller Name' => $this->callerName,
                        'Caller Phone Number' => $this->callerPhoneNumber,
                        'Applied Tags' => $tags,
                        'Call Details Page' => $callLink,
                    ]);
            });
    }

@nathan-io you defined the routeNotificationForSlack on your notification class instead of the user model. If you move it there, the notification will be sent. See the docs here: https://laravel.com/docs/9.x/notifications#routing-slack-notifications

🤦‍♂️ Thank you, that indeed resolved it.
