What sslcertificates.io can do
Caddy deployment Prefers pointing Caddy at the platform ACME directory. File/admin API cert load is used only when ACME is not appropriate. ssh/WinRM sessions use pinned host keys. Caddy admin API load or ACME endpoint mode Capabilities: atomic_write, config_test, reload, tls_verify, rollback. Authentication uses api_token.
Required permissions
Restricted service account. Commands are allowlisted: Caddy admin API load or ACME endpoint mode. Known-host verification is mandatory.
Setup
Open Dashboard → Integrations → Caddy. 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.
Known limitations
User-supplied shell is rejected. A successful file write is not enough; the TLS endpoint must present the new fingerprint.
