How to determine if a domain is available for use.

Prerequisites

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

  • A domain (for example contoso.onmicrosoft.com).

C#

To verify if a domain is available, first call IAggregatePartner.Domains to obtain an interface to domain operations. Then call the ByDomain method with the domain to check. This method retrieves an interface to the operations available for a specific domain. Finally, call the Exists method to see if the domain already exists.

// IAggregatePartner partnerOperations;
// const string domain = "contoso.onmicrosoft.com";

bool result = partnerOperations.Domains.ByDomain(domain).Exists();

Sample: Console test app. Project: Partner Center SDK Samples Class: CheckDomainAvailability.cs
