CertFusion

CertFusion is a WordPress plugin that connects a site to a CertFusion account through a personal API token. It functions as a pure API client for issuing, managing, and verifying digital certificates without requiring changes to any CertFusion server.

The plugin provides a connection settings page that includes a one-click test connection feature displaying account details and remaining quota. Within the WordPress admin, a recipient manager allows browsing certificate lists, adding recipients with custom fields, issuing certificates to individuals or in bulk, and deleting recipients. A native recipient form collects name, email, and custom fields before automatically issuing a certificate upon submission; the form incorporates nonce protection, a honeypot, and per-IP throttling. A verification widget lets visitors look up issued certificates by email and receive direct view and download links. Shortcodes and blocks are available for embedding the form.

It is delivered as a plugin listed in the official WordPress.org directory and is intended for WordPress site administrators who maintain a CertFusion account. The description on the plugin page states that it is used to issue, manage, and verify CertFusion certificates from WordPress.
