Public certificates for validation on server side

Hello Dev-Team,

We have a plugin customer that hosts Haiilo in private cloud under its own domain and with its own certificates. These certificates will expire in a few days. So far we have been manually downloading them from https://plugins.coyoapp.com analogous to the Haiilo certificates (e.g. https://plugins.coyoapp.com/certificate/coyostaging.com.v3.cert.pem). However, the old certificates are still stored there for the customer.

How do I get the new certificates?

We need this certificate in our server to secure specific endpoints.
