Updating resources

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.

Caution: update_product_labels overwrites any existing labels. So if a product already has the label "style=womens" and the following function is used to add "onSale=true" the "style" label will be removed.

Command-line

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.

curl -X PATCH \
-H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
-H "Content-Type: application/json" \
https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id -d "{
   'updateMask': { 'paths': ['display_name'] },
   'product': { 'display_name': 'new-display-name' }
