Class Method Details

.new_for_domain(domain, **params) ⇒ Client

Note:

This method will not verify that the created client has a valid connection, it will only perform the necessary lookups to build a connection URL.

Create a new client instance from only a Matrix HS domain

This will use the well-known delegation lookup to find the correct client URL
