Cynergy Bank
Cynergy Bank Account & Transaction Information API (AIS)

Cynergy Bank's implementation of the OBIE Read/Write Account & Transaction Information (AISP) API, allowing FCA/EEA-regulated Account Information Service Providers to retrieve customer account, balance, transaction, and product data with customer consent. FAPI-secured (OAuth2/OIDC, mTLS, PSD2 SCA). The harvested OpenAPI is the shared OBIE Read/Write standard the interface conforms to, not a Cynergy-proprietary contract.
