Webhook suddenly stopped working today

[TMatthews]

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??

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.

Hi, @TMatthews 👋 Is this issue persisting? Can you provide any additional details?

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.

When I just looked, yes it was still failing.
