# Configuration & resilience for an APIMatic PHP SDK Everything is set on the client builder at construction time (see **php-client-initialization**). There is no per-request options argument and no way to reach the underlying HTTP client. ```php $client = {Client}Builder::init() ->environment(Environment::{CONSTANT}) ->timeout(30) // SECONDS ->enableRetries(true) ->numberOfRetries(3) ->maximumRetryWaitTime(30) // REQUIRED — see below; 0 retries nothing ->build(); ``` > The `maximumRetryWaitTime` line is not optional. `MAXIMUM_RETRY_WAIT_TIME` is generated per SDK and is > commonly `0`, and a budget of `0` fits no backoff interval, so > `enableRetries(true)` plus `numberOfRetries(3)` without it retries **nothing**. Check the constant in > `src/ConfigurationDefaults.php`. ## Read the real defaults — they are generated, not universal `src/ConfigurationDefaults.php` holds a `public const` for every option. **Those constants are this SDK's defaults**; they are fixed when the SDK is generated, so they differ from SDK to SDK. Read them rather than assuming: `TIMEOUT`, `ENABLE_RETRIES`, `NUMBER_OF_RETRIES`, `RETRY_INTERVAL`, `BACK_OFF_FACTOR`, `MAXIMUM_RETRY_WAIT_TIME`, `RETRY_ON_TIMEOUT`, `HTTP_STATUS_CODES_TO_RETRY`, `HTTP_METHODS_TO_RETRY`, `ENVIRONMENT`, `PROXY_CONFIGURATION`. The one default that does **not** vary: `ENABLE_RETRIES` is always generated as `false`. ## Retries The values below are an **illustrative po
