Integrate once. Transact with every connected counterparty.
Fingrid OneKey is our API access program — programmatic entry to the lending rails for partners and lenders alike. Partners integrate once and reach every connected lender; lenders integrate once and receive from every connected partner. This is not Fingrid Connect: Connect is matchmaking between businesses; OneKey is API access to rails.
OneKey for partners. OneKey for lenders.
OneKey for partners
One integration to submit files and receive decisions across every connected lender — instead of building and maintaining a separate integration per lender portal.
OneKey for lenders
One integration to receive files from every connected partner — sourcing volume without an integration project per counterparty.
One format
Files, statuses and decisions move in one canonical format — mapped once to each side's systems, reused forever.
One identity
OneKey rides the shared identity layer — your entity onboards once, transacts everywhere, with every counterparty knowing exactly who they're dealing with.
How access works
Lending APIs
Submit files, track status and receive decisions programmatically against connected counterparties.
Sandbox-first
Build and certify against a sandbox before a single live file moves.
Flexible integration paths
Full API for engineering teams; lighter paths — hosted journeys and file-based exchange — where a full build isn't warranted.
Usage-based
Priced for the long tail — pay for calls, not seats.
Long Tail Aggregation Program
Small DSAs and BCs often can't carry LSP compliance obligations alone. The Long Tail Aggregation Program places them under a compliant aggregation umbrella — disclosure, consent and grievance handling operated centrally, so the smallest channel partner can still work with regulated lenders correctly.
- Aggregator-of-record handles LSP obligations; sub-partners operate under its cover
- Every sub-partner still gets a canonical network identity — no anonymous intermediaries
- Lenders see the full chain: who sourced, under whose umbrella, with what disclosures
