Hi @Beggers - it’s not pilot error 
Until very recently no HSBC credit cards and savings accounts were available as part of Open Banking interfaces. They have just switched this on for savings and credit cards should apparently be next week.
That said, we need a little time to work with these new accounts and to check their new interfaces are stable and working as expected. We hope to make these account types available as quickly as possible.
We are keeping a post updated here as we add new accounts:
