Thanks, optional suggestions below.

To get rid of the Anys (which should be Incompletes):

Suggested change

	is_ssl: Any
	ssl_certificate: Any
	is_ssl: bool
	ssl_certificate: bool | str | None

https://github.com/braintree/braintree_python/blob/a05909893e332879297dbf560431c8ae32aa657b/tests/unit/test_environment.py#L38C1-L42

ssl_certificate is passed to request's send() method, which takes bool | str | None as verify argument:

Hmmm, just because it's passed to send() doesn't mean that bool | str | None is the correct type, though -- maybe it's always a str, in which case bool | str | None will cause false positives. For now, I think I'll just use Incomplete for ssl_certificate

Suggested change

	self, name, server: str, port, auth_url: str, is_ssl, ssl_certificate, graphql_server: str = "", graphql_port: str = ""
	self, name, server: str, port, auth_url: str, is_ssl: bool, ssl_certificate: bool | str | None, graphql_server: str = "", graphql_port: str = ""
