Hi @Ryan ,
It looks like we may be suffering from this too so we're addressing the cert issue on our side for now. We're not ready yet, but once we are, would it be possible to have the unsent webhooks, resent to us?
We can post back here once we're ready if that's OK.
Thanks very much,
I just wanted to mention that it turns out I had exactly the same issue with the AddTrust (Sertigo) root certificate expiring which was preventing the webhooks from coming through. Since I've re-issued and re-installed my certificate, the hooks have started flowing normally again.
I've reached out to support to see if the missed hooks can possibly be re-sent so, fingers crossed. Just glad this one's solved.
