require 'contentful'

	def initialize(data)
		@data = data
	end

	def headers

	Contentful::Response.new(DummyResponse.new(json))
end

#p parse_response(File.read('cf-2.json')).object

client = Contentful::Client.new(
  access_token: 'b4c0n73n7fu1',

#p builder.run

p builder.run.file.url

@sebbean Sorry, I don't work at Contentful anymore at this point and can't say if this still works. Probably best to email support.
