Retrieve Force.com registered domain

Question

I need to return this value:

Is there anyway to get the registered Force.com domain for a given org, with raw Apex code or Metadata API?

Answer 1

You just need SOQL/SOSL on the Domain object. Just to double check, I looked at a domain, saw a url of instance.salesforce.com/0I4?parameters=values, and ran:

system.debug(Id.valueOf('0I4000000000000').getSObjectType()); // yields Domain

The Domain Name column you have highlighted is represented by the Domain field, leading to a somewhat silly looking query:

SELECT Domain FROM Domain

---

I have also found that with any Site records configured, you get one record in that list view that is not a domain at all, but a link to your Site tab. The url you land on if you follow the link will look like instance.salesforce.com/0DM?parameters=values. If you want the value of the "Domain Name" from that column, you have to get a bit more hack-y. I modified the code posted there by @mattandneil just a bit to get the exact value:

Site site = [SELECT GuestUserId FROM Site WHERE UrlPathPrefix != null LIMIT 1];

String path = '/sites/servlet.SiteDebugMode';
PageReference pr = new PageReference(path);
pr.getParameters().put('sitedebugmode', 'x');
pr.getParameters().put('guid', site.GuestUserId);
String url = pr.getContent().toString().substringAfter('URL=').substringBefore(path);

system.debug(url.substringBetween('//', '/'));

I do not believe this behavior is supported, but it has worked for at least two years, and does so currently.

Answer 2

you can store this in custom setting. Although if you still need this in that case you can take help from URL class

Url.getSalesforceBaseUrl().getHost();

or you can query Domain sObject

Select id,Domain from domain
