On March 14, 2019, Shopify introduced a limit of how many Products/Variants apps will be able to create using API.
You can find Shopify documentation about it here.
The limit is currently set to 1000 variants per 24 hour period once a shop has created 50,000 Product Variants (subject to change).
What can you do about it?
- Contact the Shopify Support and ask them to increase your store limit – explain the reasons behind your request.
- Upgrade your Shopify store to Shopify Plus. You can directly contact the Shopify Plus team to do the upgrade.
- You can wait till the process ends, LitExtension automatically import next 1000 items the next day.
