@ambercunningham Just a note, the link provided in this post ( https://www.tindie.com/api/v1/order/?format=json&username=...&api_key=...) contains what appears to be personal customer information (emails, addresses, etc). Additionally, there doesn't appear to be a way to RESET or REVOKE an API key which is quite unsecure. I would, at a minimum, suggest you redact the username and api key in that post and probably reset, revoke, or renew the API key for that user in your backend.
On an unrelated note, are there plans for a more fully featured API? I'd like to integrated Tindie into a project I'm working on and I need to be able to pull product costs and shipping rates via the API. Ultimately the project would send customers over to Tindie so this would be a "win-win" for us both!
