  • Credentials as described in Partner Center authentication. This scenario supports authentication with both standalone App and App+User credentials.

Make a one-time purchase

To make a one-time purchase, use the following steps:

  1. Enablement - (Azure Reserved VM Instance only) Register an active CSP Azure subscription to enable it for purchasing any reservation product.
  2. Discovery - Find and select the products and SKUs you want to purchase and check their availability.
  3. Order submission - Create a shopping cart with the items in your order and submit it.
  4. Get order details - Review the details of an order, all the orders for a customer, or view orders by billing cycle type.

After you have made your one-time purchase, the following scenarios show you how to manage the lifecycle of your products by getting information about your entitlements, and how to retrieve balance statements, invoices, and invoice summaries.


Once you have identified the active subscription that you want to add the Azure Reserved VM Instance to, you must register the subscription so that it is enabled. To register an existing Subscription resource so that it is enabled, see Register a subscription.

After registering your subscription, you should confirm that the registration process is completed by checking the registration status. To do this, see Get subscription registration status.


Once the subscription is enabled, you're ready to select products and SKUs and check their availability using the following Partner Center API models:

  • Product - A grouping construct for purchasable goods or services. A product by itself is not a purchasable item.
  • SKU - A purchasable Stock Keeping Unit (SKU) under a product. These represent the different shapes of the product.
  • Availability - A configuration in which a SKU is available for purchase (such as country, currency and industry segment).

Before making a one-time purchase, complete the following steps:

  1. Identify and retrieve the Product and SKU that you want to purchase. You can do this by listing the products and SKUs first, or If you already know the IDs of the product and SKU, selecting them.

  2. Check the inventory for a SKU. This step is only needed for SKUs that are tagged with an InventoryCheck prerequisite.

  3. Retrieve the availability for the SKU. You will need the CatalogItemId of the availability when placing the order. To get this value, use one of the following APIs:

Order submission

To submit your order, do the following:

  1. Create a cart to hold the collection of catalog items that you intend to buy. When you create a Cart, the cart line items are automatically grouped based on what can be purchased together in the same Order.

  2. Check out the cart. Checking out a cart results in the creation of an Order.

Get order details

Once you have created your order, you can retrieve the details of an individual order using the order ID, or get a list of orders for a customer. Note that there is a delay of up to 15 minutes between the time an order is submitted and when it will appear in a list of a customer's orders.

Lifecycle management

As part of managing the lifecycle of your one-time purchases in Partner Center, you can retrieve information about your Entitlements, and get reservation details using the reservation order ID. For examples of how to do this, see Get entitlements.

Invoice and reconciliation

The following scenarios show you how to programmatically view your customer's invoices, and get your account balances and summaries that include one-time charges.

Balance and payment
To get current account balance in your default currency type that is a balance of both recurring and one-time charges, see Get your current account balance

Multi-currency balance and payment
To get your current account balance and a collection of invoice summaries containing an invoice summary with both recurring and one-time charges for each of your customer's currency types, see Get invoice summaries.

To get a collection of invoices that show both recurring and one time charges, see Get a collection of invoices.
