[ARCHIVED] Getting Error 404 using API to back up Knowledge Base

I'm attempting to back up the articles and access the columns (section, creation date, etc).  I used this script as the jumping off point and everything seems to function.  Unfortunately I get a 404 back every single time.  Can someone more experienced with Python/API please help me troubleshoot this:

import os
import datetime
import csv

import requests

# selet the brand
product = 'collisionlinkinsurance'

# Set the request parameters

credentials = 'keena.tomko@oeconnection.com', 'Password'
zendesk = 'https://{product}.zendesk.com'.format(product=product)
print(zendesk)
language = 'en_us'

date = datetime.date.today()
backup_path = os.path.join(str(date),product, language)
if not os.path.exists(backup_path):
os.makedirs(backup_path)
print(backup_path)

log = []

endpoint = zendesk + '/api/v2/help_center/{locale}/articles.json'.format(locale=language.lower())
while endpoint:
response = requests.get(endpoint, auth=credentials)
if response.status_code != 200:
print('Failed to retrieve articles with error {}'.format(response.status_code))
exit()
data = response.json()

for article in data['articles']:
if article['body'] is None:
continue
title = '<h1>' + article['title'] + '</h1>'
filename = '{id}.html'.format(id=article['id'])
with open(os.path.join(backup_path, filename), mode='w', encoding='utf-8') as f:
f.write(title + '\n' + article['body'])
print('{id} copied!'.format(id=article['id']))

log.append((filename, article['title'], article['author_id']))

endpoint = data['next_page']

with open(os.path.join(backup_path, '_log.csv'), mode='wt', encoding='utf-8') as f:
writer = csv.writer(f)
writer.writerow( ('File', 'Title', 'Author ID') )
for article in log:
writer.writerow(article)
