Sectigo has the ability to ‘push’ information about issued certificates to your system when the certificates are signed.
The signed certificate and certificate chain can optionally also be pushed to your system.
This ‘push’ mechanism allows us to notify you when your certificates change status or are signed and available. The signed certificate itself can also optionally be included along with the certificate chain,
or you can choose not to have the certificate sent and use the status push to trigger a call to the CollectSSL API.
Please see the attached document.
