@annashamray hmm that's right, though if it's on the detail view, it isn't really convenient if you want to check multiple subscriptions, because you'd have to open every detail page. Maybe there should be a button/action to trigger it?

Also come to think of it, I'm not sure if the Abonnementen page is the right place for this, shouldn't it be the Webhook subscriptions?

@annashamray I've changed it to a custom admin action with a shortcut button to trigger it for all Subscriptions. I've also added a filter on the result to make it easier to check which status checks failed
