# Configuration & resilience for an APIMatic C# SDK Everything is configured on the client `Builder` at construction (see **csharp-client-initialization**). Transport tuning is **nested inside the `HttpClientConfig` action** — it is not on the client `Builder` directly: ```csharp var client = new PaypalServerSdkClient.Builder() .Environment(PaypalServerSdk.Standard.Environment.{Member}) .HttpClientConfig(config => config .Timeout(TimeSpan.FromSeconds(30)) // TimeSpan — not an int of seconds .NumberOfRetries(3) .MaximumRetryWaitTime(TimeSpan.FromSeconds(30))) .Build(); ``` Those values are **a policy you are choosing**, not this SDK's defaults. There is no `PaypalServerSdkClient.Builder.Timeout(...)`, whatever `doc/client.md` lists — see **csharp-client-initialization** for why that table is not a contract. ## The `HttpClientConfiguration.Builder` surface | Method | Type | Meaning | | --- | --- | --- | | `Timeout(TimeSpan)` | `TimeSpan` | http client timeout | | `NumberOfRetries(int)` | count | times a request is retried | | `BackoffFactor(int)` | multiplier | exponential backoff between retry calls | | `RetryInterval(double)` | `double` | interval between the endpoint calls | | `MaximumRetryWaitTime(TimeSpan)` | `TimeSpan` | cap on the whole retried call, not just the waiting | | `StatusCodesToRetry(IList<int>)` | statuses | which statuses invoke a retry | | `RequestMethodsToRetry(IList<HttpMethod>)` | `System.Net.Http.HttpMethod
