You need to follow these simple steps to update or edit any product field on Wish.com.
Export(download) CSV file.
Edit or update the product fields you want to change in the same CSV file.
Now import that CSV file in the “Wish Marketplace integration” app.
New changes will be saved and updated on the integration app. You can then upload and update it on “Wish.com.”
Note: Once the edit is made using the CSV file, the auto-sync setting will be disabled from the product level. i.e., any changes in the same Shopify product will not be auto-updated on Wish.com or on the app. To enable synchronization between Shopify and Wish, you must enable the sync setting at the product level.
For example, You have exported a product CSV and made changes in the "description." So after you have imported the CSV into the App, the description will be updated, and from the product sync settings, the "Description" update will be disabled automatically. This means no description for that particular item would be synced from Shopify.
To enable syncing, go to “Product> Manage product> Edit product> product syncing settings> enable product field> save.”
