Updating a product

You can update a product's labels via key-value pairs, such as "style=womens" or "onSale=true", using the following code.


To update a product, send a PATCH request to the following URI.
  • Replace project-id with the id of your Google Cloud project.
  • Replace location-id with a valid location identifier. Valid location identifiers are: us-west1, us-east1, europe-west1, and asia-east1
  • Replace product-id with the id for the product to update.
