Hello, I am new to the companies house streaming API and I can’t seem to get it working. Here is my code, please let me know if I have made some obvious mistakes 
import requests
import base64
api_key = ‘my api key’
api_key_with_colon = f"{api_key}:"
print(api_key_with_colon)
encoded_credentials = base64.b64encode(api_key_with_colon.encode(‘ascii’)).decode(‘ascii’)
print(encoded_credentials)
headers = {
‘Authorization’: f’Basic {encoded_credentials}’
}
print(headers)
The streaming endpoint URL
url = ‘https://stream.companieshouse.gov.uk/filings’
stream_timeout = 600
response = requests.get(url, headers=headers, stream=True, timeout=stream_timeout)
if response.status_code == 200:
print(‘Connection successful, starting stream…’)
for json_line in response.iter_lines():
if json_line:
print(json_line.decode(‘utf-8’)) # Decoding from bytes to string
else:
print(‘Empty pulse’)
else:
print(f"Connection failed with status code {response.status_code}. Response: {response.text}")
Every time I run this code i get this error and I am not sure why.
Connection failed with status code 401. Response: {“error”:“Invalid Authorization”,“type”:“ch:service”}
Any help would be greatly appreciated, Thankyou !
