Purchase a commitment Offer by using the Cloud Commerce Consumer Procurement API

You can purchase offers by using the Cloud Commerce Consumer Procurement API, an API for making Cloud Marketplace purchases.

Today, the API is in Preview, and only spend-based commitments can be purchased via the API. This how-to describes how to purchase a spend-based commitment.

Before you begin

Enable the Cloud Commerce Consumer Procurement API for your Google Cloud project.
Ensure that you have one of the following Identity and Access Management (IAM) roles for the Cloud Billing account you want to use to purchase the commitment:
- Billing Administrator (roles/billing.admin) for the target Cloud Billing account OR the Google Cloud organization where your billing account is located.
- Consumer Procurement Order Administrator (roles/consumerprocurement.orderAdmin) for the target Cloud Billing account OR the Google Cloud organization where your billing account is located.

Identify the Offer you want to purchase

To purchase a spend-based commitment, you use an Offer name which indicates the product you're purchasing and the discount term.

The following Offers are available for purchase:

Product	Term	Offer name
VMWare Engine	1 year	`services/vmwareengine.googleapis.com/standardOffers/094acb28-d4fc-49fb-9490-0c469cc7048e`
VMWare Engine	3 years	`services/vmwareengine.googleapis.com/standardOffers/f179581e-c899-4271-9462-9f9e0ed1526c`
Compute Engine flexible commitment	1 year	`services/compute.googleapis.com/standardOffers/ffe0f6a3-2f98-437e-8d49-fc443a05d3c2`
Compute Engine flexible commitment	3 years	`services/compute.googleapis.com/standardOffers/062a285d-8989-4ce7-8f9a-bed8d183236f`

Identify the Offer parameters

Commitments have two parameters:

Commitment amount (hourly_commit): The credit applied to your Cloud Billing account each hour after you purchase this commitment.
Region (region): The region for which this commitment's credits apply.

When you purchase a commitment, you must specify both parameters.

Products have specific values and constraints for their parameters. For example, if you want to purchase VMWare Engine, you might refer to the following values and constraints:

Product	Minimum commitment	Maximum commitment	Regions
VMWare Engine	$5 per hour	$10,000 per hour	asia-northeast1 asia-south1 asia-southeast1 australia-southeast1 europe-west2 europe-west3 europe-west4 northamerica-northeast northamerica-northeast1 southamerica-east1 us-central1 us-east4 us-west2

Purchase the Offer

To purchase an Offer, call billingAccounts.orders.place, and supply the following parameters:

The hourly_commit indicating the dollar value of the commitment.
The region to purchase the commitment for.

To place an order, run the following command:

curl 'https://cloudcommerceconsumerprocurement.googleapis.com/v1alpha1/billingAccounts/BILLING_ACCOUNT_ID/orders:place' \
    --header 'Content-Type: application/json' \
    --header 'Authorization: Bearer ACCESS_TOKEN' \
    --header 'X-Goog-User-Project: CONSUMER_PROJECT_ID' \
    -d '@-' <<EOF
    {
    "displayName": "DISPLAY_NAME",
    "lineItemInfo": [{
        "parameters": [{
        "name": "hourly_commit",
        "value": {
            "doubleValue": HOURLY_COMMIT
        }
        }, {
        "name": "region",
        "value": {
            "stringValue": "REGION"
        }
        }],
        "offer": "OFFER_NAME"
    }]
    }
EOF

This returns the name of a long-running operation:

{
    "name": "OPERATION_NAME"
}

To verify that the returned long-running operation completed successfully, run the following command:

curl 'https://cloudcommerceconsumerprocurement.googleapis.com/v1alpha1/OPERATION_NAME' \
    --header 'Content-Type: application/json' \
    --header 'Authorization: Bearer ACCESS_TOKEN' \
    --header 'X-Goog-User-Project: CONSUMER_PROJECT_ID'

The long-running operation should complete in less than one second.
