Retrieving specific conversations using Tweepy – Twitter API

Here is my code to get the conversation_id and also to download the conversations. Hopefully it helps people with similar issues. I have only included the required functions not the whole files, so I haven't listed the modules required like requests and base64, but they should be quite obvious.

The code to get the bearer token and create the header I got from here with the Twitter API - how can I get authentication for the engagement endpoint using a bearer token but I reposted below for convenience

# returns a bearer_header to attach to requests to the Twitter api v2 enpoints which are 
# not yet supported by tweepy 
def get_bearer_header():
   uri_token_endpoint = 'https://api.twitter.com/oauth2/token'
   key_secret = f"{twitter_creds.consumer_key}:{twitter_creds.consumer_key_secret}".encode('ascii')
   b64_encoded_key = base64.b64encode(key_secret)
   b64_encoded_key = b64_encoded_key.decode('ascii')

   auth_headers = {
       'Authorization': 'Basic {}'.format(b64_encoded_key),
       'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
       }

   auth_data = {
       'grant_type': 'client_credentials'
       }

   auth_resp = requests.post(uri_token_endpoint, headers=auth_headers, data=auth_data)
   bearer_token = auth_resp.json()['access_token']

   bearer_header = {
       'Accept-Encoding': 'gzip',
       'Authorization': 'Bearer {}'.format(bearer_token),
       'oauth_consumer_key': twitter_creds.consumer_key 
   }
   return bearer_header

# Returns the conversation_id of a tweet from v2 endpoint using the tweet id
def getConversationId(id):
   uri = 'https://api.twitter.com/2/tweets?'

   params = {
       'ids':id,
       'tweet.fields':'conversation_id'
   }
   
   bearer_header = get_bearer_header()
   resp = requests.get(uri, headers=bearer_header, params=params)
   return resp.json()['data'][0]['conversation_id']

# Returns a conversation from the v2 enpoint  of type [<original_tweet_text>, <[replies]>]
def getConversation(conversation_id):
   uri = 'https://api.twitter.com/2/tweets/search/recent?'

   params = {'query': f'conversation_id:{conversation_id}',
       'tweet.fields': 'in_reply_to_user_id', 
       'tweet.fields':'conversation_id'
   }
   
   bearer_header = twitter_auth.get_bearer_header()
   resp = requests.get(uri, headers=bearer_header, params=params)
   return resp.json()
