* If istio-agent does not find either the socket, or the certificate files in their respective paths it will start its own SDS Server using a `caClient` to connect to istiod or an external CA, to fetch cryptographic materials (See Default CA Flow).

## Order matters

When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

And then you can also have a path `/users/{user_id}` to get data about a specific user by some user ID.
