#finally(&block) ⇒ Object

Allows you to specify a something that will always be executed after a call API call. Unlike the after block, this code will run even on unsuccesful requests. This will make sure that the ApiLogger is opened and closed around every request

Examples:

class ExampleAPI < Grape::API
  before do
    ApiLogger.start
  end
  finally do
    ApiLogger.close
  end
end

Parameters:

  • ensured_block (Proc) —

    The block to be executed after every api_call
