Microsoft Dynamics CRM getting organization(s) endpoint

Microsoft Dynamics CRM Online gives you options for segregating your CRM data and user access. For most companies, adding and using multiple instances in your subscription provides the right mix of functionality and ease of management. Enterprises with separate geographic locations might consider using multiple tenants to separate Microsoft Dynamics CRM Online licenses. Multiple instances can share users among instances; multiple tenants cannot.

In order to get instances (Organization) configured in your account we use discovery service. Discovery service provides the organizations that are available on your Microsoft Dynamics Server. It uses SOAP protocol. 

Given below list of discovery service (Online) hosted by Microsoft for different geo locations.

Location	Discovery Web service URL	Identity Provider
North America	https://dev.crm.dynamics.com/XRMServices/2011/Discovery.svc	Microsoft account
	https://disco.crm.dynamics.com/XRMServices/2011/Discovery.svc	Microsoft Office 365
North America 2	https://disco.crm9.dynamics.com/XRMServices/2011/Discovery.svc	Microsoft Office 365
Europe, Middle East and Africa (EMEA)	https://dev.crm4.dynamics.com/XRMServices/2011/Discovery.svc	Microsoft account
	https://disco.crm4.dynamics.com/XRMServices/2011/Discovery.svc	Microsoft Office 365
Asia Pacific Area (APAC)	https://dev.crm5.dynamics.com/XRMServices/2011/Discovery.svc	Microsoft account

For On-Premise the URL would be: 

http://ServerName/XRMServices/2011/Discovery.svc

Code to get organization endpoints for all the instances configured in Microsoft Dynamics CRM Online.

string discoveryURL = https://disco.crm5.dynamics.com/XRMServices/2011/Discovery.svc";                 

          

//Pass your online account credentials           

ClientCredentials credentials = new ClientCredentials();

credentials.UserName.UserName = "abhishek@xxxxxxxxx.onmicrosoft.com";

credentials.UserName.Password = "xxxxxxxxxxx";

//Create discovery service proxy

DiscoveryServiceProxy dsp = new DiscoveryServiceProxy(new Uri(discoveryURL), null, credentials, null);

dsp.Authenticate();

          

//Retrieve Organization details

RetrieveOrganizationsRequest orgRequest = new RetrieveOrganizationsRequest();

RetrieveOrganizationsResponse allOrgs = (RetrieveOrganizationsResponse)dsp.Execute(orgRequest);

//Print all organization(s)(instances) endpoint.

foreach (OrganizationDetail orgInfo in allOrgs.Details)

   {               

     Console.Write(orgInfo.Endpoints[EndpointType.OrganizationService]);

   }

Console.ReadLine();
