Hampden & Co

Hampden & Co Account & Transaction Information API

OBIE Read/Write Account Information Service (AIS) - accounts, balances, transactions, beneficiaries, standing orders, direct debits, statements, and parties - as a FAPI-secured PSD2 dedicated interface. The harvested OpenAPI is the shared OBIE Read/Write standard (v4.0.1), not a Hampden-proprietary contract; production access requires TPP onboarding with eIDAS/OBIE certificates.
