How to find partner role for account

Question

Recently I enabled Partner Community for one of existing Accounts. As I noticed the new Role was created with the similar name of my Account - I assume this role can be used to share records with recently created Partner Account's employees (partner users)

Q: How to exactly determine Partner Community Role by Account Id? Is there any link between Partner Account and automatically created Role?

Answer 1

Found the reference to partner account in UserRole object. So in order to get automatically created Group for Partner Account you will need to do something like:

UserRole portalRole = [SELECT ParentRoleId FROM UserRole WHERE 
    PortalAccountId = :portalAccount.Id 
    LIMIT 1];
Group partnerPortalGroup = [SELECT Id, Name, 
    DeveloperName, RelatedId, Type, Email 
    FROM Group WHERE 
    RelatedId = :portalRole.Id];
