CertFu management API

August 25, 2026

Today we’re pleased to release a new management API for CertFu, our ACME-enabled, private certificate authority.

This is in addition, of course, to the ACME API, which remains the standard interface for ACME-compatible clients.

This new management API is for use outside ACME clients, such as for automated provisioning and auditing. The API covers:

  • EAB tokens (external account bindings) and ACME client account keys, for automated provisioning of ACME clients that need certs.
  • Directories and CA certs, for automated provisioning of your private CA infrastructure itself.
  • Orders and Issued certs, for reviewing and auditing cert issuance across your infrastructure.

All told, this makes it easier than ever to integrate a private CA with the rest of your infrastructure.

More information on the management API can be found in the CertFu API docs.

As always, don’t hesitate to reach out if you have questions about the CertFu API or anything else!

Cloning resources and enhanced metadata

August 17, 2026

Two updates today for DNScaster.

First, we’ve added a new Clone feature for IP Monitors and Boundaries. This parallels similar functionality already available for Hosts and makes quick work of creating new Monitors or Boundaries that are substantially similar to existing ones.

Second, several API resources now sport a new field, properties, suitable for storing per-record metadata as key/value pairs.

This succeeds the prior external_ref field which is now deprecated. Whereas external_ref stored only a single value, properties allows multiple key/value pairs making it much more flexible and perfect for storing data related to the integration of DNScaster with your other infrastructure.

APIs for listing resources, such as List Zones, may also now filter based on properties.

To learn more, see the Properties API docs.
