Erste Group exposes an open banking API built on the Berlin Group NextGenPSD2 standard, covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII). Beyond the regulated PSD2 baseline it also offers 4 premium API categories: real-time balances, statement reporting, multi-bank aggregation and FX & hedging.
Access uses OAuth 2.0 with redirect SCA, over a REST interface. A self-service sandbox lets you build and test before you apply for production access.
The API is offered in Austria, Czechia, Slovakia, Hungary, Romania, Croatia and Serbia. BankSnipe rates Erste Group's API maturity 5/5 (Mature), last reviewed 10 Jun 2026.

Erste Group API: frequently asked questions
Does Erste Group have a public API?
Yes. Erste Group publishes regulated PSD2 open banking APIs covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII), plus premium APIs beyond that baseline. Registration and documentation live on its developer portal at https://developers.erstegroup.com.
Does Erste Group offer an API sandbox?
Yes. The sandbox is self-service, so you can sign up and start calling it without a commercial agreement in place.
Which open banking standard does the Erste Group API use?
Berlin Group NextGenPSD2: the most widely used European open-banking API standard. Two banks on the same standard can still differ in the details, so read the bank's own documentation before you build.
How do you authenticate with the Erste Group API?
OAuth 2.0, with redirect SCA for the customer consent step. Production access to the regulated endpoints also means registering as a licensed third-party provider with the bank.
Does Erste Group offer premium APIs beyond PSD2?
Yes. We have recorded 4 premium categories on Erste Group: real-time balances, statement reporting, multi-bank aggregation and FX & hedging. These sit above the regulated PSD2 baseline and are the ones corporate treasury teams tend to care about.
Which countries does the Erste Group API cover?
Austria, Czechia, Slovakia, Hungary, Romania, Croatia and Serbia.
Is the Erste Group API free to use?
Banks generally do not charge licensed third-party providers for the regulated open banking endpoints, which is the point of the mandate. Premium APIs above that baseline are commercial products priced by the bank. BankSnipe does not track pricing, so confirm it with the bank.
How mature is the Erste Group API?
BankSnipe scores it 5 out of 5 (Mature). The score counts how many of the four product signals are live: AIS, PIS, CBPII and premium APIs beyond the regulated PSD2 baseline.
