Getting and listing resources

At any time you can list and get any product set, product, or reference image resources you have.

Listing product sets

You can have multiple product sets. This section describes how to retrieve a list of all your product sets.

Command-line

To get a list of all of the product sets for a GCP project, send a request to the following URI.

Replace project-id with the id of your Google Cloud Platform (GCP) project.
Replace location-id with a valid location identifier. Valid location identifiers are: us-west1, us-east1, europe-west1, and asia-east1.

curl -X GET -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
-H "Content-Type: application/json" \

Getting a single product set

You can get a single product set to use or modify.

Command-line

To get the information for a product set, send a request to the following URI.

Replace project-id with the id of your Google Cloud Platform (GCP) project.
Replace location-id with a valid location identifier. Valid location identifiers are: us-west1, us-east1, europe-west1, and asia-east1.
Replace product-set-id with the id for the product set that you want to get.

Listing products

You may wish to view all products in a Google Cloud Platform project. The following example shows how to list products in a given project.

Command-line

To get a list of all of the products for a GCP project, send a request to the following URI.

Replace project-id with the id of your Google Cloud Platform (GCP) project.
Replace location-id with a valid location identifier. Valid location identifiers are: us-west1, us-east1, europe-west1, and asia-east1.

curl -X GET -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
-H "Content-Type: application/json" \

To list the products for a product set, send a request to the following URI.

Replace project-id with the id of your Google Cloud Platform (GCP) project.
Replace location-id with a valid location identifier. Valid location identifiers are: us-west1, us-east1, europe-west1, and asia-east1.
Replace product-set-id with the id for the product set that you is associated with the products that you want to list.

Getting a single product

You can also get a single product to use or modify.

Command-line

To get the information for a single product, send a request to the following URI.

Replace project-id with the id of your Google Cloud Platform (GCP) 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 that you want to get.

Listing reference images

A product can have multiple associated reference images. The following example describes how to obtain all reference images linked to a single product.

Command-line

To list the reference images for a product, send GET request to the following URI.

Replace project-id with the id of your Google Cloud Platform (GCP) 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 that is associated with the images.

curl -X GET -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/referenceImages

If the response contains a nextPageToken, there are more results. You can repeat the request, adding a pageToken parameter with the value of nextPageToken (for example, 1LqhSgZfM_uWKOxvog):

curl -X GET -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/referenceImages?pageToken=nextPageToken-value
