# Managing Open Banking Integration

## When To Use

- Onboarding a new third-party provider (TPP) or data aggregator that needs API access to customer accounts
- Evaluating or upgrading an existing open banking platform (e.g., migrating from screen-scraping to API-based access)
- Preparing for regulatory compliance under PSD2, Open Banking Standard (UK), Consumer Data Right (AU), or CFPB Section 1033 (US) [VERIFY jurisdiction-specific framework]
- Designing or auditing the consent lifecycle for customer-permissioned data sharing
- Coordinating multi-party integration across account-servicing payment service providers (ASPSPs), payment initiation service providers (PISPs), and account information service providers (AISPs)

## Inputs To Gather

- **Regulatory scope**: Applicable open banking regime and mandatory API standards (Berlin Group NextGenPSD2, UK OBIE, FDX, etc.) [VERIFY which standard governs the target market]
- **API specification**: Target version of the open banking API spec, supported endpoints (AIS, PIS, CBPII), and sandbox/production URLs
- **TPP registry entries**: Provider eIDAS certificates or registry status (e.g., FCA register, national competent authority directory) [VERIFY registry source]
- **Consent parameters**: Data clusters to be shared (account balances, transaction history, standing orders), consent duration, and re-authorization cadence
- **Current architecture**: Existing core banking APIs, middleware/gateway stack, authentication protocols (OAuth 2.0 / FAPI profile), and token management approach
- **Security posture**: TLS requirements, certificate pinning policy, mutual TLS (mTLS) configuration, and penetration test schedules
- **Customer experience flows**: Screen mockups or journey maps for consent grant, dashboard management, and consent revocation

## Workflow

1. **Scope the integration**
   - Identify participating roles: ASPSP, AISP, PISP, CBPII provider
   - Confirm regulatory classification of each party and required permissions [VERIFY license/registration status of each TPP]
   - Define data-sharing perimeter: which account types, data fields, and payment rails are in scope

2. **Map the consent lifecycle**
   - Design the Strong Customer Authentication (SCA) flow for initial consent grant (redirect vs. decoupled vs. embedded approach)
   - Define consent object attributes: permissions requested, expiration policy, frequency-of-access limits
   - Specify re-authorization triggers (90-day SCA renewal under PSD2 RTS, or equivalent) [VERIFY re-auth cadence per local regulation]
   - Document revocation paths: customer-initiated (dashboard, call center), TPP-initiated, and ASPSP-initiated

3. **Configure API gateway and security layer**
   - Register TPP client credentials; validate eIDAS QWAC/QSeal certificates or equivalent [VERIFY certificate scheme]
   - Implement OAuth 2.0 authorization code flow with PKCE; enforce FAPI 1.0 Advanced or FAPI 2.0 profile if required
   - Enable mTLS between TPP and ASPSP; configure certificate rotation schedules
   - Set rate limits, throttling tiers, and error-response standards per API specification

4. **Build and test data-sharing endpoints**
   - Implement account information endpoints (GET /accounts, GET /transactions, GET /balances) conforming to target spec
   - Implement payment initiation endpoints if PIS is in scope (POST /payments, GET /payment-status)
   - Validate response payloads against official schema validators (e.g., OBIE Conformance Suite, Berlin Group test harness)
   - Run functional, performance, and negative-path test suites in sandbox before production cutover

5. **Establish operational monitoring**
   - Instrument API availability and latency dashboards; define SLA thresholds (e.g., 99.5% uptime, <500 ms P95 latency) [VERIFY SLA commitments per regulatory mandate]
   - Set up alerting for consent anomalies: unusual spike in consent grants, bulk revocations, or repeated SCA failures
   - Create incident-response runbook for data-breach scenarios involving shared account data
   - Schedule quarterly TPP access reviews and annual penetration tests

6. **Compile integration report**
   - Summarize integration status per TPP: onboarded, in testing, blocked, decommissioned
   - Document outstanding issues, dependency risks, and remediation timelines
   - Include consent analytics: active consent volume, revocation rates, re-authorization success rates
   - Flag items requiring escalation to compliance, information security, or executive stakeholders

## Output

The deliverable is a **Management Report** containing:

- **Integration status matrix**: TPP name, role (AISP/PISP/CBPII), onboarding stage, go-live date, and current health status
- **Consent lifecycle summary**: Flow diagrams, consent duration policies, re-authorization schedule, and revocation statistics
- **Security configuration record**: Authentication profile, certificate details, mTLS status, rate-limit settings, and last penetration test date
- **API performance dashboard snapshot**: Uptime percentage, latency percentiles, error rates, and SLA compliance
- **Risk and issue log**: Open items with severity, owner, and target resolution date
- **Recommendations**: Next-phase integrations, spec version upgrades, or regulatory changes requiring action

## Quality Checks

- Every TPP listed has a verified registration/license entry in the applicable regulatory directory [VERIFY]
- Consent flows comply with SCA requirements for the governing regulation; 90-day re-auth rule addressed if PSD2 applies [VERIFY]
- API responses validated against the official schema; no undocumented fields exposed
- Security configuration meets or exceeds FAPI profile requirements; mTLS enforced for all production traffic
- Rate limits and error codes align with the published API specification
- Report includes no inferred compliance statuses — any unconfirmed item is marked [VERIFY]
- Customer-facing consent language reviewed for clarity and completeness (plain-language requirement under most regimes) [VERIFY]
