UK Open Banking Standard
The UK's API specifications, security profile and customer experience guidelines for open banking.
The UK Open Banking Standard is the set of API specifications, security profiles and customer experience guidelines that UK account providers use to give regulated third parties access to accounts and payments. It includes read and write APIs for account information, payment initiation and variable recurring payments, and its security profile is based on the OpenID Foundation's financial-grade API work. It is a mature reference for how a customer's delegated authority can be expressed and enforced in an API.
