Open Banking UK
UK Open Banking standard defining REST APIs that regulated banks must expose for Account Information (read account/transaction data) and Payment Initiation (trigger payments) with standardized OAuth2/FAPI authentication.
Best When
You're a regulated financial services firm (AISP/PISP) in the UK and need direct, standardized access to bank account data or payment initiation across UK banks.
Avoid When
You're not FCA-authorized as an AISP or PISP — retail use requires going through a regulated aggregator like TrueLayer or Plaid.
Use Cases
- • Aggregating bank account balances and transaction history for personal finance agents
- • Initiating payments directly from bank accounts (payment initiation) in financial workflows
- • Account verification for KYC/KYB workflows using official bank data
- • Building financial dashboards with real bank transaction categorization
- • Direct debit and standing order management via Variable Recurring Payments (VRP)
Not For
- • Non-UK bank accounts (use open banking standards specific to EU, AU, or Brazil)
- • Teams needing a single API to aggregate UK banks (use Plaid UK or TrueLayer instead)
- • Real-time payment confirmations with sub-second requirements
