ruby - Get values from Hash

I have value response_data which stores this data:

{"response_data"=>
  {"transaction_type"=>"void",
   "status"=>"error",
   "unique_id"=>"ec8b1e786efe64f667ad19ff1b39fb92",
   "transaction_id"=>"kcyplptlpk966yifmuct6jj0od",
   "code"=>"410",
   "technical_message"=>"no approved reference transaction found",
   "message"=>"Something went wrong, please contact support!",
   "mode"=>"test",
   "timestamp"=>"2017-11-24T08:07:40Z",
   "descriptor"=>"rwgwg",
   "sent_to_acquirer"=>"false"}}

How I can get the keys from this structure?
