Primary Webhook Not Triggering because of Error: certificate authority (CA) isn’t recognized
If the error says the certificate authority (CA) isn’t recognized and your payload is being sent to the failover webhook url instead of the primary then that means the connection can’t be established over https.
We have two options here:
(a) make sure your server has a certificate that is signed by a known CA
(b) use http instead of https
