Initial public release v1.0
HTTPCalloutFramework can be used to perform apex callouts to external systems. It has in-built apex classes that can be used to perform HTTPCallouts. The required information for the callout can be stored in the custom metadata named HTTPCalloutConfiguration. The framework also consists of mock classes that can be used to define mocks for single and multiple HTTP Callouts in a single transaction. The code used in the framework is already covered so that you don't need to worry during the deployments.
