⚡ Reliability
Best When
A Belgian or European fintech, accountant, or payment service provider wanting AI agents to initiate PSD2 bank payments, aggregate EU bank account data, and connect to Belgian Isabel business banking through Ibanity's open banking platform.
Avoid When
STRONG CUSTOMER AUTHENTICATION REQUIRED: PSD2 SCA (Strong Customer Authentication) mandates two-factor bank authentication for all payments; automated one-click payment initiation assumption creates SCA_required challenge; automated must implement SCA redirect or app-to-app decoupled authentication. EU BANKS ONLY: Ibanity covers 200+ European banks but not global institutions; automated worldwide bank coverage assumption creates unsupported_institution; automated must verify target bank is in Ibanity's EU institution coverage list. AIS CONSENT HAS 90-DAY EXPIRY: PSD2 AIS bank data access consents expire after 90 days; automated permanent data access assumption creates expired_consent error; automated must implement consent refresh workflow before 90-day expiry. ISABEL CONNECT IS BUSINESS BANKING: Isabel Connect integration covers Belgian corporate banking (ING, BNP Paribas, KBC corporate) — different from retail PSD2; automated retail/corporate equivalence assumption creates wrong product; automated must choose correct product (PSD2 for retail, Isabel Connect for corporate).
Use Cases
- • Initiating PSD2-compliant bank payments from Belgian and EU consumer bank accounts for checkout automation agents
- • Aggregating account data from 200+ European banks for PSD2 AIS personal finance management automation agents
- • Connecting Belgian business banking (Isabel Connect) for corporate payment automation agents
- • Processing bulk payment batches from EU bank accounts for payroll and AP automation agents
Not For
- • Non-EU markets (Ibanity focuses on Belgian and European banking under PSD2)
- • Card payment processing (Ibanity is bank-to-bank transfer and account data, not card acquiring)
- • Consumer cryptocurrency transactions (Ibanity is traditional EU banking connectivity)

Agent Metadata
Known Gotchas
- ⚠ MTLS CLIENT CERTIFICATE REQUIRED: Ibanity API requires mutual TLS (mTLS) with client certificate in addition to OAuth2; automated standard bearer token assumption creates TLS handshake failure; automated must configure client certificate authentication in HTTP client
- ⚠ SCA REDIRECT IS MANDATORY: PSD2 Strong Customer Authentication requires user redirect to bank for two-factor authentication; automated server-side payment initiation without SCA creates SCA_required challenge; automated must implement SCA redirect flow for all payment initiations
- ⚠ AIS CONSENT EXPIRES IN 90 DAYS: PSD2 AIS consent is valid for maximum 90 days per EBA guidelines; automated permanent consent assumption creates consent_expired on day 91; automated must implement proactive consent renewal before expiry
- ⚠ ISABEL CONNECT VS PSD2 ARE SEPARATE PRODUCTS: Belgian corporate banking uses Isabel Connect (different API endpoints from PSD2); automated unified API assumption creates wrong product endpoint; automated must determine whether target use case is retail PSD2 or corporate Isabel Connect
- ⚠ NBB LICENSE REQUIRED FOR PRODUCTION PIS: Initiating payments as a PISP requires NBB payment institution license or passporting; automated unlicensed payment initiation in production creates regulatory violation; automated must have appropriate NBB PISP license or use Ibanity as licensed PISP
