Native Magento comes with a lot of REST APIs for different Entities like Product, Order, Customer, and other APIs.
I want to give a demo for updating bulk products using rest API in Magento 2.
By Default Native Magento doesn’t provide Bulk Product Update API. You need to call REST API to iterate over a loop. At a time you can update only a single product.

Hi Rakesh,
I have tried above example, Create module and call using postman but give me an below error
“message”: “%fieldName is a required field.”,
“parameters”: {
“fieldName”: “Products”
},
Can you help me how to resolve?
Thanks,
