Access uses OAuth 2.0 with redirect SCA, over a REST interface. A sandbox is available, though access is not self-service.
The API serves Slovenia. BankSnipe rates NLB's API maturity 4/5 (Established), last reviewed 15 Jun 2026.

NLB API: frequently asked questions
Does NLB have a public API?
Yes. NLB publishes regulated PSD2 open banking APIs covering account information (AIS), payment initiation (PIS) and confirmation of funds (CBPII). Registration and documentation live on its developer portal at https://developer.nlb.me.
Does NLB offer an API sandbox?
Yes. Sandbox access is available but not self-service, so you go through the bank to get in.
Which open banking standard does the NLB 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 NLB 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 NLB offer premium APIs beyond PSD2?
Not that we have recorded. NLB's listing covers the regulated PSD2 baseline only.
Which countries does the NLB API cover?
Slovenia.
Is the NLB 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 NLB API?
BankSnipe scores it 4 out of 5 (Established). The score counts how many of the four product signals are live: AIS, PIS, CBPII and premium APIs beyond the regulated PSD2 baseline.
