Overview

Class responsible for facilitating communication with the Worldline Acquiring platform. It combines the following classes to provide communication functionality:

api_endpoint

the base URL to the Worldline Acquiring platform

connection

Worldline::Acquiring::SDK::Communication::Connection used to communicate with the Worldline Acquiring platform

authenticator

Authentication::Authenticator used for authenticating messages sent

metadata_provider

Worldline::Acquiring::SDK::Communication::MetadataProvider object containing information relevant for sending requests

marshaller

JSON::Marshaller that is used to marshal and unmarshal data to and from JSON format

def close
  @connection.close
end

#close_expired_connections ⇒ Object

Closes any connections that have expired. Will not have any effect if the connection is not a pooled connection (an instance of Worldline::Acquiring::SDK::Communication::PooledConnection).
