Cashplus Bank
Cashplus Bank (legal entity Advanced Payment Solutions Limited, rebranded to Zempler Bank in July 2024) is a UK challenger bank founded in 2005 that grew from a prepaid-card issuer into a fully licensed bank, receiving its UK banking licence in 2021 and regulated by the Financial Conduct Authority (FCA) and the Prudential Regulation Authority (PRA). It focuses on business current accounts, personal current accounts, credit cards, and payments for micro-enterprises, sole traders, and small-to-medium businesses. Following a 2026 acquisition it operates as a subsidiary of The Access Bank UK (part of Nigeria's Access Bank plc). As an FCA-authorised ASPSP it participates in UK Open Banking under PSD2, publishing Read/Write APIs conformant to the Open Banking Implementation Entity (OBIE) standard - Account Information (AIS), Payment Initiation (PIS), and Confirmation of Funds (CBPII) - secured with FAPI-grade OAuth2/OIDC, mutual-TLS, PSD2 strong customer authentication, and OBIE/eIDAS certificates. Cashplus is not one of the CMA9 mandated banks. Alongside the regulated Open Banking surface it runs a first-party partner/developer platform documenting proprietary Identity, Accounts, Applications, Eligibility, Payments, Products, and Transactions APIs for embedded and commercial integrations.
Cashplus Bank publishes 24 APIs on the APIs.io network, including Cashplus Accounts API, Cashplus Products API, Cashplus Transactions API, and 21 more. Tagged areas include Financial-Services, Banking, Open Banking, PSD2, and OBIE.
Cashplus Bank’s developer surface includes authentication, documentation, engineering blog, legal docs, support, and 27 more developer resources.
