To get Autofac integrated with Web API you need to reference the Web API integration NuGet package, register your controllers, and set the dependency resolver. You can optionally enable other features as well.

protected void Application_Start()

{

  var builder = new ContainerBuilder();

  // Get your HttpConfiguration.

  var config = GlobalConfiguration.Configuration;

  // Register your Web API controllers.

  builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

  // OPTIONAL: Register the Autofac filter provider.

  builder.RegisterWebApiFilterProvider(config);

  // OPTIONAL: Register the Autofac model binder provider.

  builder.RegisterWebApiModelBinderProvider();

  // Set the dependency resolver to be Autofac.

  var container = builder.Build();

  config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

}

The sections below go into further detail about what each of these features do and how to use them.
