TSB Bank API: frequently asked questions
Does TSB Bank have a public API?
Yes. TSB Bank publishes regulated PSD2 open banking APIs covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII). Registration and documentation live on its developer portal at https://apis.developer.tsb.co.uk.
Does TSB Bank offer an API sandbox?
Yes. Sandbox access is available but not self-service, so you go through the bank to get in.
Which open banking standard does the TSB Bank API use?
UK Open Banking: the API standard mandated for UK banks. Two banks on the same standard can still differ in the details, so read the bank's own documentation before you build.
How do you authenticate with the TSB Bank API?
OAuth 2.0, with redirect SCA for the customer consent step. Production access to the regulated endpoints also means registering as a licensed third-party provider with the bank.
Does TSB Bank offer premium APIs beyond PSD2?
Not that we have recorded. TSB Bank's listing covers the regulated UK Open Banking baseline only.
Which countries does the TSB Bank API cover?
the United Kingdom.
Is the TSB Bank API free to use?
Banks generally do not charge licensed third-party providers for the regulated open banking endpoints, which is the point of the mandate. Premium APIs above that baseline are commercial products priced by the bank. BankSnipe does not track pricing, so confirm it with the bank.
How mature is the TSB Bank API?
BankSnipe scores it 4 out of 5 (Established). The score counts how many of the four product signals are live: AIS, PIS, CBPII and premium APIs beyond the regulated UK Open Banking baseline.
