# Client

This page lists the Go SDK names for the [Client](https://docs.superdurable.io/concepts/client.md).
The doc comment of each API gives its parameters, defaults, and errors. Read
them in the [Go SDK API reference](https://docs.superdurable.io/reference/go.md#api-reference).

Every **Client** method that calls Dex Server takes a **context.Context** as
its first argument. Canceling a wait ends the call. It does not stop the Flow.
