Required permissions

Read-only query. Not an SLA dependency.

Setup

Open Dashboard → Integrations → crt.sh. Enter the credentials described on this page. Values are encrypted at rest and never shown again. Run Test connection. Discovery runs only after authentication succeeds. Select a discovered resource. Do not paste opaque IDs unless the provider cannot enumerate them. Perform the certificate or notification action, then confirm the external system matches. Disconnect removes stored credentials and owned test resources created by sslcertificates.io.
