Descriptions: We are working in Rest API for to create and update products on shopify site. When we send request to create or update products to shopify site, It takes long time to return response. For example, 500 products take 2 hours approximately create/update. We need to reduce this time to in few mininutes instead of hours. So, is there any options to upload bulk operations in Rest API? or anything? If yes, could you please let us know the example or reference details on site?
