I have an YML file :
{language: en, pipeline: null, policies: null}
version: '2.0'
intents: [greet, goodbye, affirm, deny, mood_great, mood_unhappy, bot_challenge]
responses:
  utter_greet:
  - {text: 'Hey! How are you?'}
  utter_cheer_up:
  - {text: 'Here is something to cheer you up:', image: 'https://i.imgur.com/nGF1K8f.jpg'}
  utter_did_that_help:
  - {text: 'Did that help you?'}
  utter_happy:
  - {text: 'Great, carry on!'}
  utter_goodbye:
  - {text: Bye}
  utter_iamabot:
  - {text: 'I am a bot, powered by Rasa.'}
session_config: {session_expiration_time: 60, carry_over_slots_to_new_session: true}
Now How to send a POST request using POSTMAN... I need to send a POST request but in POSTMAN I'm unable to set the requestbody type to x-yaml.?
