Uma das principais funcionalidades necessárias em sistemas de API é a "<dfn title="também chamado: marshalling, conversão">serialização</dfn>" de dados, que é pegar dados do código (Python) e convertê-los em algo que possa ser enviado pela rede. Por exemplo, converter um objeto contendo dados de um banco de dados em um objeto JSON. Converter objetos `datetime` em strings, etc.

	// A client may send a certificate chain such that we end up
	// with multiple peer certificates. However, we can only accept
	// a single client certificate. Otherwise, the certificate to
	// policy mapping would be ambiguous.
	// However, we can filter all CA certificates and only check

              (System.nanoTime() - startNanos) / 1e9f, e);
        }
      }
    ```

### Timeouts ([.kt][ConfigureTimeoutsKotlin], [.java][ConfigureTimeoutsJava])

Use timeouts to fail a call when its peer is unreachable. Network partitions can be due to client connectivity problems, server availability problems, or anything between. OkHttp supports connect, write, read, and full call timeouts.
