# Certificates

A certificate in Qyrus API is used for securing communication between the Qyrus client and a server during API requests. Certificates are an integral part of establishing secure connections over HTTPS (Hypertext Transfer Protocol Secure) and are used to authenticate the server's identity and encrypt the data being transmitted.

When you send API requests from Qyrus API to a server using HTTPS, the server presents its digital certificate to prove its identity. Qyrus API Service can verify the authenticity of the certificate by checking whether it's issued by a trusted Certificate Authority (CA) and matches the server's domain.
