How do I deactivate a Portal User in Apex Code?

Question

Is it possible to deactivate a Customer Portal user using Apex?

Answer 1

// Assume cIds is a list of Contacts whose users we wish to deactivate
List<User> usersToUpdate = new List<User>();
for(User u : [Select u.Id, u.IsActive, u.IsPortalEnabled from User u where u.ContactId    in :cIds]){
    if(u.IsActive || u.IsPortalEnabled ){
        u.IsActive = false;
        u.IsPortalEnabled = false;
        usersToUpdate.add(u);
    }
}

if (usersToUpdate.size()>0){
    update usersToUpdate;
}

The above snippet might help.

This question was asked and last answered back in 2013. In 2021, it seems that attempting to update User.isActive in the same update operation that sets User.isPortalEnabled will actually cause the update operation to fail.

When you set User.isPortalEnabled = false SFDC will automatically set User.isActive to false and User.ContactId to null, which is what we want.

So, for a collection of Contact ID's named "contactIds" that are related to User records you would like to disable:

List<User> usersToDisable = [select id from User where ContactId in :contactIds];
for (User u : usersToDisable) {
  u.isPortalEnabled = false;
}
update usersToDisable;
