viaBanking Banking API review
A normalized REST API for bank data, payments and verification, with a free sandbox.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
viaBanking Banking API gives developers and financial services teams one REST API for connecting to banks, electronic money institutions and open banking providers across European markets. It normalizes bank access and data models for account information, payment initiation, account verification, transaction retrieval and webhooks. The product is a fit for teams building financial applications that need a connectivity layer; regulated AIS and PIS services are provided by licensed partner institutions rather than viaBanking itself.
The free Sandbox plan offers access without a card and includes sample-data AIS and PIS calls through simulated API flows. That gives developers a way to work with the API before production. Production is usage-based and includes live access to C2B accounts across Europe, AIS and PIS in one connection, and volume usage rates on request. The vendor describes coverage as 2,500+ banks and EMIs, but does not tie that figure to a stated count in a specific paid plan. Buyers should request rates to assess production costs.
On the integration side, the normalized REST API covers balances and transactions, transaction history, and account ownership, IBAN and name-match verification. Payment initiation supports single, bulk and recurring payments where supported. Signed webhooks cover consent, payment and account-state changes, while bank-hosted consent and strong customer authentication are handled via licensed providers. Documentation is the listed support channel. Choose viaBanking if a free sandbox and a single connectivity API fit your development needs; consider alternatives if you need published production rates or a provider that itself supplies the regulated services.
