I found an interesting article about Open Banking the other day (via FinTech Insider News). Its title is: Open Banking in the UK; a disaster in the making? no wonder it intrigued me. However, I clicked the article open and the first paragraph read:
When the CMA Order went live on 13/1/18, aside from the banks, there were no PISP authorised TPPs, there remain very few today, and there is no sign of a customer (PSU) facing service using APIs available on the open market. The question is why, the answer is simple – the authorisation journeys.
