Class Method Details

.build(api_instance_class:, agent_settings:, logger: Datadog.logger, api_version: nil, headers: nil, &block) ⇒ Object

Helper function that delegates to Builder.new but is under HTTP namespace so that client code requires this file to get the adapters configured, and not the builder directly.
