I have a webhook subscription hat has been working fine and all of a sudden earlier today it stopped working and is giving HTTP 400 error code, but I cant see any other details as to why it stopped working? It’s been about 9 hours and still failing? How do I troubleshoot this or get it working again??

So when I use postman everything works. but through hubspot it fails. But I hate how they have it set up. I can’t see the exact payload they are sending, just the error “HTTP 400” which doesnt tell me anything? So have no idea how to troubleshoot.

Also, no other details… I wish I did. Not sure how to even get more details. The webhook monitoring just says HTTP 400 I dont see a way to get any other details. When I click test, the test works. So not sure why it is failing when it was working fine.
