Using Magento2.1.0-rc1 Branch With Sample Data
Using REST API catalogProductRepositoryV1 REF: http://devdocs.magento.com/swagger/index.html Get Key from Admin token API and use that key in
POST /V1/products
&
PUT /V1/products/{sku}
with parameter tried with both parameter one by one
Does not support store_id / storeId field , but the information in product does not save to store it save to default Store ID
GET /V1/products has parameter storeId same i had tried with PUT & POST but not working with PUT & POST
I've encountered a similar scenario where I want to update prices per website. So to update the price, I've used
/rest/<store_code>/V1/products/<sku>
This worked fine.
So I assume you can use this to update product data per store.
