Way to identify Salesforce edition using API?

Question

Is there an API method to return what edition current customer is using?

Answer 1

You can query the OrganizationType from the Organization object.

select OrganizationType from Organization

Possible values are "Developer Edition", "Team Edition" (Group), "Professional Edition", "Enterprise Edition" and "Unlimited Edition".

Answer 2

Use below class to determine the instance and edition of salesforce.

public class whereAmI{

// First method will give us the edition as a string 

public Static String getEdition(){

    // Organization object FTW!
    Organization[] org = new Organization[]{};
    org = [select Id, OrganizationType from Organization limit 1];

    // Check to make sure we have a result
    if(org.size()==1)
        return org[0].OrganizationType;
    else
        return '[still lost...]';
}


// Next method tells us if we're in a sandbox

public Static Boolean isSandbox(){

    String host = URL.getSalesforceBaseUrl().getHost();
    String server = host.substring(0,host.indexOf('.'));

    // It's easiest to check for 'my domain' sandboxes first 
    // even though that will be rare
    if(server.contains('--'))
        return true;

    // tapp0 is a unique "non-cs" server so we check it now
    if(server == 'tapp0')
        return true;

    // If server is 'cs' followed by a number it's a sandbox
    if(server.length()>2){
        if(server.substring(0,2)=='cs'){
            try{
                Integer.valueOf(server.substring(2,server.length()));
            }
            catch(exception e){
                //started with cs, but not followed by a number
                return false;
            }

            //cs followed by a number, that's a hit
            return true;
        }
    }

    // If we made it here it's a production box
    return false;
  }
}
