# Initializing an APIMatic-generated Ruby SDK client Names below are concrete for this SDK; replace the remaining `{...}` placeholders with the real names from its source: - `{controller_name}` — a controller reader method on the client. - `{Name}` — an `Environment` constant. ## The shape: keyword arguments, no builder and no options hash The SDK exports a single `Client` class under `PaypalServerSdk`. You construct it with **keyword arguments** — a flat list, not an options object and not a builder. Every argument has a default that was fixed when the SDK was generated, so passing none is valid: ```ruby require 'paypal_server_sdk' client = PaypalServerSdk::Client.new( environment: PaypalServerSdk::Environment::{Name}, timeout: 30, # auth credential objects — see ruby-authentication # retry / proxy / callback arguments — see ruby-configuration-resilience ) ``` `Client#initialize` declares the **same** arguments as `Configuration#initialize` plus a `config:`, and simply forwards them into a new `Configuration`. Open `lib/paypal_server_sdk/configuration.rb` for the authoritative list and the real defaults — the set varies per API. In this build that set includes one credential argument per declared scheme, any server template parameters the API declares, and a `logging_configuration:`. The arguments common to every build: | Argument | Type | Purpose | | --- | --- | --- | | `connection` | `Faraday::Connection` | a Faraday connection you built yourself, used for
