Runtime configuration

At runtime, the REST library first parses the external configuration parameters and then calls the suppliers to build their instances. The following table lists the runtime configuration parameters:

Parameter	Description
`basePath`	The base path to the REST endpoint URL
`auth`	The authentication method that the REST API client uses. The following methods are supported: `HttpBasic` `HttpBearer` `ApiKey` `OAuth`
`eventHandlers`	An array of `eventHandlers` that are applied to each request. The type property determines the event handler type: `retry` `circuitbreaker` `fallback`
`loggerName`	Defines a logger for an endpoint. Use this setting to define different logger for each endpoint.
`logLevel`	Defines what information to log: `NONE` No logging `BASIC` Logs method, URL, response status, and execution time. `HEADERS` Logs the BASIC information and request/response headers. `FULL` Logs the HEADERS information, body, and metadata for request/response. By default the `logLevel` is set to NONE.
`timeout`	The timeout configuration for the request
`connectTimeoutMillis` Required	Defines the connection timeout in milliseconds. The default is set to 5 ms.
`readTimeoutMillis` Required	Defines the timeout for the waiting time on a read request. The timeout is in milliseconds. The default is 5 ms.
`httpClient`	The configuration object for an HTTP client or Mutual Transport Layer Security (TLS) authentication
`client`	An Apache `HttpClient`.
`hostnameVerifier`	A functional class that accepts a `Map<String,String>` and returns an object that implements `HostnameVerifier`. This is ignored if `ClientSupplierClass` is provided.
`context`	A functional class that accepts a `Map<String,String>` and returns an object that implements `SSLSocketFactory`.
`interceptors`	An array of additional interceptors. Interceptors provide a mechanism to intercept and/or mutate outgoing requests or incoming responses. The following interceptors are already added to the REST API client: `ForwardingInterceptor` `HttpBearerAuth` `ApiKeyAuth`
`traceActionsClass`	A class that implements `TraceabilityActions`. This is required only if you use a diagnostic context that is different than Mapped Diagnostic Context (MDC) for holding this information.
`mapper`	An object mapper
`credentialSupplier`	A functional class that accepts a key and a default value with the credentials that are used to authenticate the HTTP requests. The class returns an object the implements the `CredentialSupplier` class.
