I wrote a python script for Shoolu.com to use the BigCommerce API to pull the latest added products and generate an XML RSS file. BigCommerce did have the functionality to automatically generate these RSS feeds but they have moonlighted support and have removed it for new merchants so it didn't seem like something to rely on.
PYTHON To The Rescue
I found the BigCommerce Python API and used that to fetch all the products with a created date of at most 7 days ago. I then looped through all those products to create the nessecary items in the RSS File.
This worked well and good but I was basically just overwriting the one file and losing any previous weeks worth of New Products. I knew it would be easy enough to just write to a different file with the current date in the file name so it'd be new every time.
Trouble In Paradise
The plan was to use this RSS feed to generate a "What's new at Shoolu" email every week through MailChimp and their ability to work with RSS Feeds. The problem with the current approach of dating the files was that I was pointing Mailchimp at the one direct file so I'd have to update it every week which kind of defeats the purpose of all of this.
