See Resource references for accepted reference kinds, lookup scopes, canonical identities and exact list filters. See Resource faults for the active faults array. The certificate service issues TLS certificates for your domains and keeps them current. You give it a name and a list of domains; it proves you control them over DNS, gets them signed, and renews them before they expire. You can also upload a certificate you already hold. Certificates are attached to a load balancer listener by CRN, so the load balancer never handles your private key directly.

Issuing

The DNS challenge, start to finish, and what changes when you host the domain elsewhere.

Uploading your own

Material you already hold — active immediately, and never renewed for you.

Serving a certificate

Multi-SNI, the default certificate, and the two removals a listener refuses.

Renewal and revocation

What renews on its own, how revoking differs from deleting, and every status.

Certificate material

The only endpoint that returns the private key, and who may call it.

Permissions

Every IAM action, which call needs it, and how to scope a policy by certificate name.

Limits and troubleshooting

Stuck in pending_dns, wildcard failures, and reading faults.
