We’ve already implemented In-App-Notifications in our app, but without OneSignal. Is there a way to trigger these kind of notifications from Mautic using a server-to-server call (e.g. via a web hook), without using OneSignal as a provider?
I’d only need a REST call to an endpoint in our app that triggers and sends the contacts along which should be targeted, plus the text for the in-app notification.
I’ve seen that I can add a webhook to a campaign. But how could I add the contact (or their email) as a data payload to this hook?
