WIX Store External API?

I am revamping a website for a jewelry store and they are wanting to open an online store how ever they specialize in selling refurbished jewelry so they normally only ever have one quantity of an item. So items sold in store will have to be removed from the online shop. I had an idea to automate this by making a program that can read the reports our POS system outputs and remove the items from the store that match the specific SKU of the items sold in store. I how ever can’t find anything definitively stating if the Wix store has an API that would let a program outside of Wix interact with it. So my question is, does one exist? Thanks in advance for any information on this.

You can use HTTP functions to expose an API of your site’s functionality. So basically, you can add code to your external site so that once a user is logged in to the site, you post a message to the backend of your Wix site.

Awsome! Ill play around with this. Thanks for letting me know about it!

To build on @givemeawhisky comment.

wix-stores can track or not track inventory. It sounds like you would disable inventory tracking and manage this by yourself in a custom data collection. Then you can adjust what you display on your site using dynamic pages linked to the Stores/Products data collection.

Just to add to the idea of external access using the http-functions API. Be aware that this is not a secure API so you have to add your own security. I would take a look at the OAuth model and implement a variant of it.

With the ability to use npm modules in Wix you can enable the uuid module to give you universally unique ids for this purpose.

Good luck

Cheers
