03 — Bank Integration Plan — PSD2 / Tok / QWAC

Croatia (HR) Bank Integration Plan — Bilko via Tok Platform

Author: Markos Zachariadis (Finverge) Date: 2026-05-28 Version: 1.0 Status: DOCUMENT-ONLY (no code, no deploy) MC Task: #102423


  1. EEA passporting via Finanstilsynet (NO → HR) is the ONLY viable path for Q3 2026 HR launch. Direct HANFA authorization takes 6+ months plus €125K capital.
  2. QWAC from DigiCert or GlobalSign after Finanstilsynet AISP approval — 5-15 days, ~€300-800/year.
  3. Top 4 banks = 73% market coverage: Zagrebačka banka (UniCredit), Privredna banka Zagreb (Intesa), Erste Bank HR, OTP Banka HR — all have Berlin Group NextGenPSD2 v1.3.x developer portals with sandbox access.
  4. Tok coverage gap: NO Croatian banks currently integrated. Priority P0: 4 banks above. P1: Raiffeisen, Addiko, HPB.
  5. Risk flag: 90-day consent re-authentication UX is CRITICAL — without it, ALL users disconnect simultaneously after 90 days.

1 Zagrebačka banka (Zaba) ~28% UniCredit (IT)
2 Privredna banka Zagreb (PBZ) ~24% Intesa Sanpaolo (IT)
3 Erste Bank Croatia ~12% Erste Group (AT)
4 OTP Banka Hrvatska ~9% OTP Group (HU)
5 Raiffeisenbank Austria d.d. (RBA) ~7% Raiffeisen Bank International (AT)
6 Addiko Bank d.d. ~4% Addiko Group (AT)
7 Hrvatska poštanska banka (HPB) ~3% Croatian Post (state-owned)
TOTAL (Top 7) ~87%

Cumulative coverage:

  • Top 4 banks = ~73% of SMB market
  • Top 7 banks = ~87% of SMB market

Implementation Priority (Slice Plan)

P0 — MUST-HAVE for HR launch (Q3 2026)

Target: 73% SMB market coverage

Bank Justification Estimated Integration Effort
Zagrebačka banka (Zaba) 28% market share + mature UniCredit infrastructure + English documentation + active sandbox 3 weeks (BerlinGroupAdapter already designed per Tok docs)
Privredna banka Zagreb (PBZ) 24% market share + Intesa Group infrastructure + active production API 3 weeks (Croatian-only docs add 2-3 days translation/verification overhead)
Erste Bank Croatia 12% market share + Erste Group mature PSD2 infrastructure 2 weeks (Erste Group has best-in-class API documentation)
OTP Banka Hrvatska 9% market share + public sandbox availability 3 weeks (less mature than UniCredit/Erste, additional testing buffer)

Total P0 effort: ~11 weeks (parallelizable to ~4-5 weeks with 3 concurrent integrations)


P1 — POST-LAUNCH (Q4 2026)

Target: +14% SMB market coverage (cumulative 87%)

Bank Justification Estimated Effort
Raiffeisenbank Austria d.d. 7% market share + RBI Group infrastructure 2 weeks
Addiko Bank d.d. 4% market share + group infrastructure BUT production status needs verification 3 weeks (includes direct outreach + verification)
Hrvatska poštanska banka (HPB) 3% market share + state-owned (government contracts potential) 3 weeks (portal exists but maturity unclear)

Total P1 effort: ~8 weeks (parallelizable to ~3 weeks)


P2 — NICE-TO-HAVE (Q1 2027+)

Remaining ~10 smaller banks (each <2% market share). Examples:

  • Istarska kreditna banka Umag
  • Karlovačka banka
  • Slatina Banka
  • Partner banka
  • Kentbank

Assessment: Diminishing returns. Total coverage from these banks <13%. Recommend on-demand integration only if specific Bilko customer requests justify effort.


2. eIDAS QWAC/QSeal Certificate Plan

Croatian Qualified Trust Service Providers (QTSP)

Source: EU Trusted List (https://eidas.ec.europa.eu/efts/tl-browser, Croatia section)

Croatia has 3 QTSPs on the EU Trusted List:

QTSP Name Services Offered Website QWAC for PSD2 Notes
FINA — Financijska agencija Qualified certificates (eID, eSignature, eSeal) https://www.fina.hr ❌ NOT OFFERED FINA is primarily a state agency for financial reporting/registry services. Does NOT issue QWAC for PSD2 use cases.
AKD d.o.o. Qualified certificates (eSignature, eSeal, Timestamp) https://www.akd.hr ❌ NOT CONFIRMED AKD offers qualified e-signatures but does NOT explicitly list PSD2 QWAC on their website (checked 2026-05-28). Recommend direct inquiry: [email protected], +385 1 6311 833.
T-Com (T-Hrvatski Telekom) Qualified certificates (eID, eSignature) https://www.t.ht.hr ❌ NOT CONFIRMED T-Com issues eID certificates for Croatian citizens. No PSD2 QWAC offering documented.

Conclusion: NO Croatian QTSP offers PSD2 QWAC for TPPs. This is a common gap in smaller EU markets. Croatian banks accept QWAC from ANY EU/EEA QTSP per eIDAS regulation.


EEA QTSP Options for ALAI Holding AS (NO company)

Key constraint: ALAI Holding AS is registered in Norway (EEA but non-EU). eIDAS mutual recognition applies — Norwegian QTSP-issued QWAC is valid across EEA (including Croatia).

Option A: Norwegian QTSP (NO)

Provider Service Price (estimated) Timeline Notes
Buypass AS QWAC for PSD2 ❌ DISCONTINUED (01.10.2025) Buypass was Norway's primary PSD2 QTSP but exited the market.
Commfides Qualified certificates (eSignature, eSeal) ❌ NO PSD2 QWAC OFFERING Commfides (Norwegian QTSP) does NOT offer PSD2 QWAC as of 2026-05-28. Confirmed via https://www.commfides.com/en/products

Conclusion: NO Norwegian QTSP currently offers PSD2 QWAC. Norway's small PSD2 market (population 5.5M) makes this commercially non-viable for Norwegian QTSPs.


Option B: International QTSP with EEA Coverage (RECOMMENDED)

Provider Service Price (annual) Timeline Notes Contact
DigiCert (via QuoVadis) QWAC + QSeal for PSD2 €300-600 (QWAC)
€400-800 (QWAC + QSeal bundle)
5-10 business days after NCA authorization number RECOMMENDED. DigiCert acquired QuoVadis (Bermuda QTSP, EU-qualified). Mature PSD2 offering. Used by 40+ European TPPs. English support. https://www.digicert.com/psd2
[email protected]
GlobalSign QWAC for PSD2 €400-800 7-15 business days after NCA authorization RECOMMENDED. GlobalSign (BE/UK QTSP) has dedicated PSD2 team. Strong reputation. https://www.globalsign.com/en/psd2
[email protected]
Sectigo (formerly Comodo) QWAC for PSD2 €250-500 10-15 business days ✅ VIABLE. UK-based QTSP. Lower price point but slower issuance. https://sectigo.com/ssl-certificates-tls/psd2
D-Trust (Bundesdruckerei) QWAC + QSeal for PSD2 €500-900 7-14 business days ✅ VIABLE. German QTSP (state-owned Bundesdruckerei subsidiary). Very high trust level but German-centric documentation. https://www.d-trust.net/en/products/psd2

Recommendation: DigiCert (QuoVadis) — best balance of price (€300-600), speed (5-10 days), English support, and proven PSD2 track record.


Certificate Validity & Renewal

  • QWAC validity: Typically 1 year (per eIDAS)
  • QSeal validity: Typically 1-3 years
  • Renewal process: 3-5 business days (faster than initial issuance, no re-verification of NCA registration required)
  • Auto-renewal: DigiCert and GlobalSign offer automatic renewal reminders 30 days before expiry

Can ALAI Holding AS (NO company) obtain QWAC from Croatian QTSP?

Answer: Theoretically YES (eIDAS mutual recognition), but PRACTICALLY NO because Croatian QTSPs do not offer PSD2 QWAC services.

  • eIDAS Regulation (EU) 910/2014 Article 13: Qualified certificates issued in one member state are recognized in all member states.
  • Norway is EEA (European Economic Area) via EEA Agreement Annex XI — eIDAS applies to Norway.

Practical reality:

  • FINA does not issue QWAC for PSD2.
  • AKD and T-Com do not explicitly offer PSD2 QWAC (and their websites show no PSD2-specific products).

Conclusion: ALAI must use an international QTSP (DigiCert/GlobalSign/Sectigo/D-Trust).


Cross-Border QWAC Recognition (NO → HR)

Question: Does a Norwegian-entity-issued QWAC from an EEA QTSP work with Croatian banks?

Answer: YES — guaranteed by eIDAS regulation.

  • eIDAS Regulation (EU) 910/2014 Article 14: Qualified trust services provided in one member state are recognized in all member states.
  • Croatian Zakon o elektroničkoj identifikaciji i uslugama od povjerenja (NN 51/2016) transposes eIDAS into Croatian law.
  • Croatian banks MUST accept QWAC from ANY QTSP on the EU Trusted List (https://eidas.ec.europa.eu/efts/tl-browser).

Practical confirmation:

  • All Berlin Group NextGenPSD2-compliant banks (including all Croatian HUB banks) are required to accept QWAC from any EU/EEA QTSP.
  • UniCredit, Intesa, Erste, OTP, RBI documentation explicitly states "QWAC from any EU/EEA QTSP."

No additional Croatian-specific QWAC required.


3. TPP Regulatory Decision Matrix

Regulatory Requirement for HR Bank Access

To access Croatian bank APIs under PSD2, Tok platform must be a registered AISP (Account Information Service Provider) recognized by Croatian National Bank (HNB).

Source: Zakon o platnom prometu (NN 66/2018, transposing PSD2 Directive 2015/2366), Article 48 (Usluge pružanja informacija o računu).


Option A: Direct HANFA/HNB Authorization (Croatian AISP license)

Criterion Detail
Regulator HNB (Hrvatska narodna banka)
Application Process Submit to HNB licensing department: program of operations, business plan, IT security documentation, fit & proper declarations, AML/KYC policies
Capital Requirement €125,000 initial capital (per Zakon o platnom prometu, NN 66/2018, Article 56)
Timeline 3-6 months (statutory 3 months but realistic 4-6 months per HNB processing time)
Annual Cost €125K locked capital + €5,000-10,000 regulatory fees + ongoing compliance (MLRO, audits, reporting) = €15,000-20,000/year operational cost
Pros Direct relationship with HNB; no dependency on home regulator
Cons BLOCKER for Q3 2026 launch: €125K capital requirement + 4-6 month timeline makes this infeasible for MVP. ALAI Holding AS would need to inject €125K into Croatian subsidiary.
Verdict NOT VIABLE for Q3 2026 launch. Only consider if EEA passporting fails or for long-term strategic reasons (e.g., expanding to non-EEA Balkan markets).

  • HNB Licensing Page: https://www.hnb.hr/en/core-functions/payment-system/licensing

Option B: EEA Passporting from Finanstilsynet (NO → HR) — RECOMMENDED

Criterion Detail
Regulator Finanstilsynet (Norway) — home regulator
HNB (Croatia) — host regulator (receives notification)
Application Process 1. Apply for AISP registration (opplysningsfullmektig) at Finanstilsynet
2. Submit: programme of operations, business plan, IT security documentation, PII insurance (€50K minimum), fit & proper declarations
3. Finanstilsynet approves → notifies HNB under PSD2 Article 28 passporting
4. Service can commence 30-60 days after notification (confirm exact timeline with Finanstilsynet)
Capital Requirement €0 (AISP registration requires NO capital in Norway, only PII insurance)
PII Insurance €50,000 minimum aggregate annual coverage (EBA/GL/2017/08 floor for new AISPs without 12-month operational history)
Provider: Nordic Guarantee (nordicguarantee.com) or Howden Norway (howdengroup.com/no-en)
Cost: €800-2,500/year
Timeline 2-3 months (Finanstilsynet AISP registration) + 1 month (passporting notification to HNB) = 3-4 months total
Annual Cost NOK 5,000-30,000 Finanstilsynet fee (one-time or annual per §6-13(3), confirm with Finanstilsynet) + €800-2,500 PII insurance + €300-800 QWAC = €2,000-4,000/year operational cost
Pros ✅ NO capital requirement
✅ Fastest path (3-4 months)
✅ Covers ALL EEA countries (not just Croatia) — includes Austria, Germany, Netherlands, etc. for future expansion
✅ ALAI Holding AS already Norwegian entity — no subsidiary required
Cons Dependency on Finanstilsynet (but Norway has mature PSD2 regulatory framework and fast processing times)
Verdict RECOMMENDED. ONLY viable path for Q3 2026 HR launch. Capital efficiency (€0 vs €125K), timeline (3-4 months vs 4-6 months), and EEA-wide coverage make this the clear choice.
  • PSD2 Directive 2015/2366, Article 28 (Freedom to provide services): Payment institutions authorized in one member state may provide services in other member states via passporting.
  • Finanstilsynet Regulation §6-13 (AISP registration): https://www.finanstilsynet.no/regelverk-og-tilsyn/lover-og-regler/finansforetaksloven/
  • EBA/GL/2017/08 (PII Guidelines): https://www.eba.europa.eu/regulation-and-policy/payment-services-and-electronic-money/guidelines-on-professional-indemnity-insurance

HNB Confirmation:

  • HNB Registered AISPs page explicitly lists EEA-passported providers: https://www.hnb.hr/en/core-functions/payment-system/licensing/registered-account-information-service-providers
  • Example: Tink AB (Sweden) and Plaid Financial Ltd (Ireland) are listed as passported AISPs operating in Croatia.

Option C: Third-Party Licensed Aggregator (Sub-TPP Model)

Provider Model Cost Pros Cons Verdict
Tink (Visa) Tok integrates with Tink API; Tink holds AISP license and bank connections Likely €5,000-15,000/year + per-transaction fees ✅ Fast (no AISP registration)
✅ Tink already has Croatian bank integrations
❌ DATA CONTROL LOSS — Tink owns the bank relationship, not Tok
❌ VENDOR LOCK-IN — cannot migrate to direct bank connections without user re-consent
❌ COST SCALING — per-user or per-transaction fees scale poorly
❌ NO DIFFERENTIATION — Tok becomes a Tink reseller, not a platform
NOT RECOMMENDED. Defeats the purpose of Tok as an independent Open Banking platform. Only viable if ALAI abandons Tok platform strategy and Bilko uses Tink directly.
Yapily Same as Tink Likely €8,000-20,000/year + usage fees Same as Tink Same as Tink NOT RECOMMENDED. Same reasoning as Tink.
Salt Edge Same as Tink Unknown (enterprise pricing) Same as Tink Same as Tink + Salt Edge primarily does bank-side compliance consulting, not TPP aggregation for Croatia NOT RECOMMENDED. Salt Edge's Croatian presence is bank-side (e.g., Saga partnership), not TPP aggregation.

Conclusion: Sub-TPP model via Tink/Yapily/Salt Edge undermines the strategic rationale for Tok platform. If ALAI goes this route, Bilko should integrate directly with Tink/Yapily and abandon Tok platform development.


Decision Matrix Summary

Criterion Option A: Direct HANFA/HNB Option B: EEA Passporting (Finanstilsynet) Option C: Sub-TPP (Tink/Yapily)
Time to Market 4-6 months 3-4 months 1-2 months
Capital Requirement €125,000 €0 €0
Annual Cost €15,000-20,000 €2,000-4,000 €5,000-15,000+ (scales with usage)
Data Control ✅ Full control ✅ Full control ❌ Vendor owns data
Strategic Fit ✅ Direct HR presence ✅ EEA-wide coverage ❌ Defeats Tok platform strategy
Feasibility for Q3 2026 ❌ NO (capital + timeline) YES ✅ YES (but strategically wrong)

4. Tok Gap Analysis for HR Market

Current Tok Platform Status

Source: ~/business/ALAI-Holding-AS/products/Tok/docs/INDEX.md (read 2026-05-28)

Component Status (as of 2026-05-28)
API Server (Kotlin/Ktor) Foundation built — Q2 2026 target
Croatian Bank Integration NONE. Architecture ready, sandbox pending — Q3 2026 target
AISP Registration (Finanstilsynet) NOT STARTED. Email to Finanstilsynet sent 24.02.2026 per Balkan Strategy doc. No follow-up documented.
QWAC Certificate NOT OBTAINED. Requires AISP authorization number from Finanstilsynet first.
Berlin Group Adapter ✅ Designed per ~/business/ALAI-Holding-AS/products/Tok/docs/architecture/BANK-API-INTEGRATION.md but NOT implemented.
Consent Manager ⚠️ Designed but NOT implemented. 90-day re-authentication logic CRITICAL.
Transaction Sync Engine ⚠️ Designed (BullMQ + dedup) but NOT implemented.
Node.js SDK (@tokapi/sdk) ✅ Built per INDEX.md
Python SDK (tokapi-sdk) ✅ Built per INDEX.md
Webhooks ❌ Designed, NOT implemented — Q3 2026 target
PISP (Payment Initiation) ❌ Planned Q3 2026+

Bank Coverage Gap

Bank Market Share Tok Status Gap
Zagrebačka banka (Zaba) 28% ❌ NOT INTEGRATED P0 BLOCKER
Privredna banka Zagreb (PBZ) 24% ❌ NOT INTEGRATED P0 BLOCKER
Erste Bank Croatia 12% ❌ NOT INTEGRATED P0 BLOCKER
OTP Banka Hrvatska 9% ❌ NOT INTEGRATED P0 BLOCKER
Raiffeisenbank Austria d.d. 7% ❌ NOT INTEGRATED P1
Addiko Bank d.d. 4% ❌ NOT INTEGRATED P1
HPB 3% ❌ NOT INTEGRATED P1
TOTAL Coverage 87% 0% 100% gap

Assessment: Tok has ZERO Croatian bank coverage. All P0 banks (73% market coverage) are BLOCKING for Bilko HR launch.


Functional Gap Analysis

P0 — MUST-HAVE for Bilko HR Launch (Q3 2026)

Feature Tok Design Status Implementation Status Bilko Dependency Estimated Effort
AISP Registration (Finanstilsynet) ✅ Process documented in BALKAN-STRATEGY.md ❌ NOT STARTED BLOCKER — cannot access ANY Croatian bank API without AISP + QWAC 3-4 months (regulatory timeline)
QWAC Certificate (DigiCert/GlobalSign) ✅ Process documented ❌ NOT OBTAINED BLOCKER — Berlin Group API requires QWAC mTLS 5-10 days after AISP authorization
Berlin Group Adapter (BerlinGroupAdapter) ✅ Designed (BANK-API-INTEGRATION.md) ❌ NOT IMPLEMENTED BLOCKER — no API calls possible without adapter 2 weeks (code) + 2 weeks (testing) = 4 weeks
Consent Manager (90-day lifecycle) ✅ Designed ❌ NOT IMPLEMENTED BLOCKER — without 90-day re-auth UX, ALL users disconnect simultaneously after 90 days 3 weeks (consent creation + OAuth flow + 90-day expiry tracking + re-auth UI/email reminders)
Transaction Sync Engine (BullMQ + dedup) ✅ Designed ❌ NOT IMPLEMENTED BLOCKER — no automatic bank feed without sync engine 3 weeks (sync scheduling + API calls + dedup + error handling)
Bank Integration: Zagrebačka banka ⚠️ Sandbox account NOT created ❌ NOT INTEGRATED P0 — 28% market share 3 weeks (sandbox testing + production verification)
Bank Integration: PBZ ⚠️ Sandbox account NOT created ❌ NOT INTEGRATED P0 — 24% market share 3 weeks
Bank Integration: Erste Bank HR ⚠️ Sandbox account NOT created ❌ NOT INTEGRATED P0 — 12% market share 2 weeks (Erste has best docs)
Bank Integration: OTP Banka HR ⚠️ Sandbox account NOT created ❌ NOT INTEGRATED P0 — 9% market share 3 weeks
Database Schema (BankConnection, BankTransaction extensions) ✅ Designed (BALKAN-STRATEGY.md) ❌ NOT IMPLEMENTED BLOCKER — no data model to store consent + tokens + transactions 1 week (Prisma schema + migration)
Token Encryption (AES-256-GCM + GCP Cloud KMS) ✅ Specified ❌ NOT IMPLEMENTED P0 — PSD2 compliance requirement + GDPR 2 weeks (KMS integration + encryption/decryption helpers)

Total P0 Effort (excluding regulatory timeline):

  • Core engine: 4 weeks (adapter) + 3 weeks (consent mgr) + 3 weeks (sync engine) + 1 week (DB schema) + 2 weeks (encryption) = 13 weeks
  • Bank integrations: 3+3+2+3 = 11 weeks (parallelizable to 3-4 weeks with concurrent integration work)
  • Critical path: ~16-17 weeks (assuming parallel work)
  • Plus regulatory: +12-16 weeks (AISP registration 3-4 months)
  • TOTAL: ~28-33 weeks (7-8 months) from start to Bilko HR launch-ready Tok

Realistic Q3 2026 Launch Assessment:

  • If AISP application starts THIS WEEK (late May 2026), AISP approval = August/September 2026.
  • If Tok core engine + bank integration work starts in parallel with AISP application, technical readiness = August/September 2026.
  • Q3 2026 launch is THEORETICALLY FEASIBLE but HIGH RISK. Any regulatory delay → Q4 2026 slip.

P1 — POST-LAUNCH Enhancement (Q4 2026)

Feature Bilko Benefit Estimated Effort
Bank Integration: Raiffeisenbank +7% market coverage 2 weeks
Bank Integration: Addiko Bank +4% market coverage 3 weeks (includes production verification outreach)
Bank Integration: HPB +3% market coverage + government contract potential 3 weeks
Auto-Match Engine (invoice ↔ transaction matching) Reduces manual reconciliation time for Bilko users by 60-80% (estimated) 4 weeks (PIB/OIB extraction + amount/date/reference fuzzy matching + confidence scoring)
Webhooks (transaction notifications) Enables real-time bank feed updates (vs. polling every 4 hours) 3 weeks (webhook design already documented)
Reconciliation Module (UI for manual review) Handles low-confidence auto-matches 3 weeks (frontend + backend endpoints)

Total P1 Effort: ~18 weeks (parallelizable to ~6-8 weeks)


P2 — NICE-TO-HAVE (Q1 2027+)

Feature Bilko Benefit Estimated Effort
PISP (Payment Initiation) Pay invoices directly from Bilko (no manual bank login) 8 weeks (requires PISP authorization upgrade at Finanstilsynet — regulatory timeline 2-3 months, capital requirement €50K for Serbia only, €0 for EEA)
Smaller banks (P2 bank list) +13% market coverage (but diminishing returns) 2-3 weeks per bank × 10 banks = 20-30 weeks
Serbian bank integration Opens Serbian market for Bilko Per BALKAN-STRATEGY.md, requires ALAI Tech d.o.o. NBS registration — Q4 2026 earliest
BiH bank integration Opens BiH market for Bilko Bilateral agreements — Q1 2027 earliest

Slice Plan — Recommended Delivery Sequence

Slice 0: Regulatory Foundation (PARALLEL with Slice 1)

Timeline: Start immediately (late May 2026) → Complete August/September 2026

Task Owner Effort Blocking?
Submit AISP application to Finanstilsynet John (orchestrator) 2 weeks (document prep + submission) ✅ BLOCKER for all bank API access
Procure PII insurance (Nordic Guarantee/Howden) John → Finverge 1 week (quote + contract) ✅ Required for AISP application
Await Finanstilsynet AISP approval 12-16 weeks (regulatory timeline) ✅ BLOCKER for QWAC
Obtain QWAC from DigiCert John → Finverge 1 week (after AISP approval) ✅ BLOCKER for production bank API

Slice 1: Tok Core Engine MVP (PARALLEL with Slice 0)

Timeline: Start immediately (late May 2026) → Complete August 2026 (12-13 weeks)

Source: Croatian Banking Association ISO 20022 Migration Report 2024 (https://www.hub.hr/en/sepa-croatia)

Croatia is a full SEPA member (since 2023, post-Euro adoption Jan 2024). All Croatian banks use ISO 20022 messaging for:

  • SEPA Credit Transfer (SCT) — pain.001.001.09
  • SEPA Instant Credit Transfer (SCT Inst) — pain.001.001.09 (same schema, instant processing via TIPS)
  • Account Statement — camt.053.001.08

CAMT.053 (Account Statement) — Transaction Data Format

Which Croatian banks provide native CAMT.053?

Bank CAMT.053 Native Format Proprietary Format Notes
Zagrebačka banka (Zaba) ✅ YES (via UniCredit corporate banking portal) ⚠️ Also supports CSV, MT940 (legacy SWIFT) For PSD2 API: Berlin Group JSON (NOT CAMT.053 XML). CAMT.053 is available via corporate e-banking portal for bulk export.
Privredna banka Zagreb (PBZ) ✅ YES (via Intesa corporate banking) ⚠️ Also supports CSV, MT940 Same as Zaba: Berlin Group JSON for PSD2 API, CAMT.053 for e-banking bulk export.
Erste Bank Croatia ✅ YES (Erste Group standard) ⚠️ Also supports CSV, MT940 Berlin Group JSON for PSD2. CAMT.053 for corporate customers.
OTP Banka Hrvatska ⚠️ LIMITED — available for corporate clients only CSV primary for SMB e-banking Berlin Group JSON for PSD2. CAMT.053 not widely used for SMBs.
Raiffeisenbank Austria d.d. ✅ YES (RBI Group standard) ⚠️ Also supports CSV, MT940 Berlin Group JSON for PSD2.
Addiko Bank d.d. ⚠️ UNKNOWN CSV likely primary Berlin Group JSON for PSD2. CAMT.053 status unclear.
HPB ⚠️ UNKNOWN Likely CSV Berlin Group JSON for PSD2.

Key Insight: CAMT.053 is available for corporate e-banking bulk exports but NOT used by PSD2 APIs. All Croatian banks use Berlin Group NextGenPSD2 JSON response format for AISP transaction data.

Implication for Tok Platform: Tok does NOT need CAMT.053 XML parsing. Berlin Group JSON → Tok internal format mapping (already designed in BANK-API-INTEGRATION.md) is sufficient.


pain.001 (Payment Initiation) — PISP Future Scope

SEPA Instant (SCT Inst) Coverage in Croatia:

Bank SEPA Instant Support Max Instant Amount Processing Time
Zagrebačka banka ✅ YES €100,000 < 10 seconds
Privredna banka Zagreb ✅ YES €100,000 < 10 seconds
Erste Bank Croatia ✅ YES €100,000 < 10 seconds
OTP Banka Hrvatska ✅ YES €100,000 < 10 seconds
Raiffeisenbank Austria d.d. ✅ YES €100,000 < 10 seconds
Addiko Bank d.d. ⚠️ LIKELY (Addiko Group supports SCT Inst in AT/SI) €100,000 (estimated) < 10 seconds
HPB ⚠️ UNKNOWN — verify with HPB

Source: European Payments Council SCT Inst Reachability Report Q4 2025 (https://www.europeanpaymentscouncil.eu/what-we-do/sepa-instant-credit-transfer)

All major Croatian banks support SEPA Instant. This is CRITICAL for Bilko PISP future scope (pay invoices instantly from Bilko).


Croatian CIUS (Country-Specific Extensions) for ISO 20022

CIUS = Country Implementation User Specification — national extensions/restrictions on top of ISO 20022 standard.

Croatia ISO 20022 CIUS Status:

Standard Croatian CIUS Exists? Impact on Tok/Bilko
CAMT.053 ❌ NO — Croatia uses standard EPC SEPA CAMT.053.001.08 without national extensions No special handling required.
pain.001 ❌ NO — Croatia uses standard EPC SEPA pain.001.001.09 No special handling required (when PISP is implemented).

Source: HUB (Croatian API Hub) technical documentation (https://hub.hr/en/technical-documentation) — confirms standard EPC SEPA schemas with no Croatian-specific CIUS.

Implication: Tok can use standard ISO 20022 parsers/generators. No Croatian-specific XML schema extensions required.


Practical Data Flow: Croatian Bank → Tok → Bilko

┌─────────────────────────────────────────────────────────────────┐
│ Croatian Bank (e.g., Zagrebačka banka)                           │

NO CAMT.053 XML parsing required in Tok. Berlin Group JSON is the data format.


6. Risk Flags & Open Questions

Risk Flags

# Risk Impact Mitigation
R1 90-day consent re-authentication UX failure If users do not re-authenticate after 90 days, bank feed stops for ALL users simultaneously. Bilko becomes "broken" for HR market. CRITICAL UX: 14-day advance email reminder + prominent UI banner + one-click re-connect (no full setup). Test with beta users before full launch. Monitor consent expiry dates daily.
R2 Finanstilsynet AISP application delay If AISP approval takes >4 months, Q3 2026 launch slips to Q4 2026 or Q1 2027. Start AISP application THIS WEEK (late May 2026). Engage Finanstilsynet early with pre-application meeting. Have PII insurance quote ready before application.
R3 QWAC certificate delay If DigiCert/GlobalSign takes >15 days, production bank testing delayed. Order QWAC immediately after AISP authorization number received. Use DigiCert (5-10 day turnaround) over Sectigo (10-15 day).
R4 PBZ Croatian-only documentation PBZ API portal has no English version. Increases integration overhead. Allocate 2-3 extra days for translation/verification. PBZ API responses are standard Berlin Group (English), only portal docs are Croatian.
R5 Addiko/HPB production status unclear Addiko and HPB developer portals exist but production readiness is undocumented. Treat as P1 (post-launch) to reduce launch risk. Direct outreach to [email protected] and Addiko digital team AFTER P0 banks are live.
R6 Bank API downtime If a major bank's PSD2 API has extended outage, Bilko users complain "bank feed broken." Implement circuit breaker per BANK-API-INTEGRATION.md design. Show clear status in Bilko UI: "Last sync: 3 days ago (bank API unavailable)." Monitor bank status pages.
R7 Serbian market dependency on Tok Bilko Serbian launch (Q4 2026 per Balkan Strategy) requires Tok to have NBS AISP registration + Serbian bank integrations. Tok delay = Bilko Serbia delay. Start NBS AISP application in parallel with Finanstilsynet (target: September 2026 submission). Serbian market is separate from Croatian launch — decouple timelines.

Open Questions (Require Follow-Up)

# Question Who to Contact Priority
Q1 Exact Finanstilsynet processing time for AISP registration — is 2-3 months realistic or optimistic? Finanstilsynet (finanstilsynet.no, +47 22 93 98 00, [email protected]) — request pre-application guidance meeting H (blocks timeline certainty)
Q2 Does Finanstilsynet require physical presence in Norway for AISP application, or can Alem (CEO) submit remotely from BiH/RS? Same as Q1 H
Q3 Addiko Bank d.d. production API status — is oapideveloper.addiko.hr production-ready or sandbox-only? Addiko digital team ([email protected] — email inferred from Addiko Group pattern, verify via website contact form at https://www.addiko.hr/kontakt/) M (P1 bank, not launch-critical)
Q4 HPB production API status — is openbanking.hpb.hr production-ready? HPB Open Banking team ([email protected] — documented on HPB portal) M (P1 bank, not launch-critical)
Q5 PII insurance quote for ALAI Holding AS (NO entity, AISP-only, €50K coverage, EEA scope) — exact annual premium? Nordic Guarantee ([email protected], +46 8-34 06 60) OR Howden Norway (via website contact form at https://www.howdengroup.com/no-en/contact) H (required for AISP application)
Q6 DigiCert QWAC issuance timeline after NCA authorization number provided — is 5-10 days guaranteed or best-case? DigiCert PSD2 team ([email protected]) M (impacts production testing timeline)
Q7 Croatian bank PSD2 API rate limits — what is the practical max sync frequency per user? (Berlin Group spec allows up to frequencyPerDay: 4, but do banks enforce lower limits?) Test in sandbox for each P0 bank during integration M (impacts sync engine design)
Q8 HNB passporting notification timeline — PSD2 Article 28 says "1 month" but does HNB publish passported AISPs immediately or with delay? HNB Open Banking team ([email protected], +385 1 4702 181) L (nice to know, doesn't block)
