HTTP-01 and DNS-01 flows, including manual records and Cloudflare automation.

Automatic scheduling plus a forced renewal endpoint for tests and operations.

HMAC-SHA256 signed JSON events with retries for failed deliveries.

Stable error codes for clients. HTTP status is separate from the machine code.

How the platform talks to Let’s Encrypt staging and why production is locked.

Metadata fields stored after X.509 parsing, download rules, and key modes.

Document root, PHP 8.4, scheduler, queue worker, and backups for the Plesk host.

Additive changes stay on /api/v1. Breaking changes require a new version path.

PHP, TypeScript, Python and Go clients generated from the OpenAPI document.

The authoritative HTTP contract is served at /openapi.yaml and /openapi.json.
