Is it possible to automatically import products from other e-commerce platforms in Turkey (e.g. Trendyol, Hepsiburada) and integrate with Wix product stock when products are sold on other platforms (without using third party software)?
this will depend alot on the external providers, but here’s some ideas to start researching.
You can use wix fetch to fetch the items from an api (assuming there is one) Fetch | Velo
To do this automatically, you could set up a scheduled job to sync each day or whenever you define Schedule Jobs
Then you can use the products api to add products to the wix stores product collections - this assumes you are modifying the object to mathc the structure within wix after fetching the resource https://dev.wix.com/docs/velo/api-reference/wix-stores-backend/create-product
If the external ecom services allow webhooks you could define an http function on your wix site that you could use on the external services to send data on a trigger (if that’s available in the other services) Velo Wix Http Functions Introduction | Velo
