For a SuiteCommerce site gated behind a login: Is there any way to automatically give a new Contact login access to the store and notify them? We're having to manually update the Contact Access subtab under their respective Customer.

can you not access the contacts role list from the parent customer record? I would check there.

Yes, I want to automatically give a new contact access instead of manually navigating to the Access subtab under a customer.

I can't say if this is supported natively, but I imagine you could script a solution.
