API Tokens and Agents

What is an agent?

An agent is a small program installed on a server where there is an SSL certificate that needs to be automated.

Agents are used when the server cannot be opened to CertGuardian for certificate installation, so the server requests and installs the certificate by requesting it from CertGuardian.

API

Agents use an API that lets them check how many days remain before the certificate expires, download the certificate to install a new one, and update a certificate’s CSR.

Authentication

Authentication is done using an API Token, which must be included in the X-CG-AGENT-TOKEN header of every API call.
