Get the Salesforce Internal (non-Site) URL from a Site

Question

(This is the opposite question of Get Site URL from apex.)

I'm running Apex in a request on a Site page. URL.getSalesforceBaseUrl().toExternalForm() gives me https://siteprefix.force.com

I want my actual instance URL: https://mydomain.my.salesforce.com or even https://pod.salesforce.com. How can I get it?

Answer 1

Spring '22 solution:

Use the DomainCreator class:

String url = 'https://' + DomainCreator.getOrgMyDomainHostname();

Winter '19 solution:

// works in sites, sandboxes, custom domain, etc
String url = Url.getOrgDomainUrl().toExternalForm();

Prior to this you can leverage the salesforce Identity URL. It was the documented and supported way to obtain the API endpoints without a login or OAuth handshake. It will work for your Site Guest User too.

Answer 2

I recently faced this exact scenario and also found an answer to this. Use this code snippet to get salesforce instance url when working on a site page

ApexPages.currentPage().getHeaders().get('X-Salesforce-Forwarded-To');

Per the documentation:

X-Salesforce-Forwarded-To : The fully qualified domain name of the Salesforce instance that is handling this request. This header is always set on HTTP and HTTPS requests that are initiated outside of Salesforce's data centers.

You could use this one as well.

public String getURL() {
    return String.format(
      'https://{0}.salesforce.com',
      new String[]{
        URL.getSalesforceBaseUrl().getHost().substringAfter('.').substringBefore('.')
      });
}

Answer 4

I think I'm going to end up using a solution like this:

public String getInstanceUrl(){
   String domain = [Select d.Domain From Domain d where DomainType='DNS' Limit 1].Domain;
   if (domain==null){
       domain=URL.getSalesforceBaseURL().getHost();
   }
   return 'https://'+domain;
}

Essentially, I'm just using this to build a path to /services/apexrest/ so I prefer to just use the domain that I have configured. If for some reason the domain isn't set up, I'll just grab the Salesforce base url.

Answer 5

This isn't an exact answer to my question, but it solved my needs in this case. Instead of using the specific mydomain id, I found that I could get by with a generic reference to login.salesforce.com (for production) or test.salesforce.com (for sandboxes).

As such, the following was a close-enough approximation:

public String getInternalUrl() {
    String host = URL.getSalesforceBaseURL().getHost();

    // if host has a token of form csXX or tapp0, it's a sandbox
    if (host.contains('cs') || host.contains('tapp')) {
        return 'https://test.salesforce.com';
    } else {
        return 'https://login.salesforce.com';
    }
}

Answer 6

I had the exact same problem and was able to solve for this by querying the Organization object and building the URL manually. Eg.

String orgInstance = [SELECT InstanceName FROM Organization][0].InstanceName; // Returns CS17 for example.

String instanceUrl = 'https://' + orgInstance.toLowerCase() + '.salesforce.com';

This will return the instance URL, regardless if accessed from external site.

Answer 7

You should use this:

String currentRequestURL = URL.getCurrentRequestUrl().toExternalForm();

This will return complete URL into String form with all parameters and structure.

Try this URL class

System.URL.getSalesforceBaseURL().getHost();
