Error Adding Webhook

Originally posted by Ryan Curran

After having reviewed https://developer.servicem8.com/docs/webhooks-overview
I am on List Webhook Subscriptions

Neither page tells me what to pass in the body of the Post call.

I am trying this : {“object”:“job”, “fields”:“status”, “callback_url”:“https://hook.integromat.com/rxxxxxxx”}

but getting error message : Please specify an object for subscription

what do I need to change for this to work?
