How to get the subscription registration status for a customer subscription that has been enabled for purchasing Azure Reserved VM Instances.

To purchase an Azure Reserved VM Instance using the Partner Center API, you must have at least one existing CSP Azure subscription. The Register a subscription method allows you to register your existing CSP Azure subscription, enabling it for purchasing Azure Reserved VM Instances. This method allows you to retrieve the status of that registration.

Prerequisites

Credentials as described in Partner Center authentication. This scenario supports authentication with both standalone App and App+User credentials.
A customer ID (customer-tenant-id). If you don't know the customer's ID, you can look it up in Partner Center by selecting the Customers workspace, then the customer from the customer list, then Account. On the customer’s Account page, look for the Microsoft ID in the Customer Account Info section. The Microsoft ID is the same as the customer ID (customer-tenant-id).
A subscription ID.

C#

To get the registration status of a subscription, begin by using the IAggregatePartner.Customers.ById method with the customer ID to identify the customer. Then, get an interface to subscription operations by calling the Subscription.ById() method with the subscription ID to identify the subscription. Next, use the RegistrationStatus property to obtain an interface to the current subscription's registration status operations, and call the Get or GetAsync method to retrieve the SubscriptionRegistrationStatus object.

// IAggregatePartner partnerOperations;
// var selectedCustomerId;
// var selectedSubscriptionId;

// Retrieve a subscription's registration status details.
var subscriptionRegistrationDetails = partnerOperations.Customers.ById(selectedCustomerId).Subscriptions.ById(selectedSubscriptionId).RegistrationStatus.Get();
