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

When you send a PATCH request all previous fields and their values will be erased except for the productCategory field, which is immutable. Send all fields you need with values when making the PATCH update request.

Before using any of the request data below, make the following replacements:

• project-id: Your GCP project ID.
• location-id: A valid location identifier. Valid location identifiers are: us-west1, us-east1, europe-west1, and asia-east1.
• product-id: The ID for the product that is associated with a reference image. This ID is either randomly set or specified by the user at product creation time.
• display-name: A string display name of your choosing. This can be the same as the previous display name or an updated value.
• description: A string description of your choosing. This can be the same as the previous display name or an updated value. Omit the description field and value if you don't need it.
• productLabels: One or more key-value pairs associated with a product. Each key-string must have an associated value-string.

HTTP method and URL:

PATCH https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id

Request JSON body:

{
  "displayName": "display-name",
  "description": "description",
  "productLabels": [
    {
      "key": "key-string",
      "value": "value-string"
    },
    {
      "key": "key-string",
      "value": "value-string"
    }
  ]
}

To send your request, choose one of these options:

curl

Note: Ensure you have set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path for your service account private key file.

Save the request body in a file called request.json, and execute the following command:

curl -X PATCH \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id

PowerShell

Note: Ensure you have set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path for your service account private key file.

Save the request body in a file called request.json, and execute the following command:

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method PATCH `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -InFile request.json `
  -Uri "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "name": "projects/project-id/locations/location-id/products/product-id",
  "displayName": "display-name",
  "description": "description",
  "productCategory": "apparel-v2",
  "productLabels": [
    {
      "key": "style",
      "value": "womens"
    },
    {
      "key": "onSale",
      "value": "true"
    }
  ]
}
