We have make new mobile app for online store and we have some of vendors with their site (Wix Online Store) on Wix. So, we need to fetch their store products in to out app.
For that We need to create App on your app store. when any of our vendors installed that app in to his store and authorize. after that we can sync his store products to our app so that vendors have no need to add products manually in to our app and he can easily mange their products from your panel only.
Can you suggest the way from where we can start and can you please provide any API or SDK for the same.
