# Managing API Banking Analysis

Structures banking API evaluation with functionality assessment, security review, and integration planning.

## When To Use

- Evaluating a banking API provider (e.g., Plaid, MX, Yodlee, Finicity) for new or existing product integration
- Conducting a comparative analysis across multiple API vendors for core banking, payments, or account aggregation
- Assessing API security posture before signing a vendor agreement or during periodic review
- Planning migration from one banking API to another or from screen-scraping to API-based connectivity
- Reviewing API capabilities against regulatory requirements (PSD2, Open Banking, FDX standards) [VERIFY jurisdiction-specific mandates]

## Inputs To Gather

- **API provider documentation** — endpoint catalog, sandbox access credentials, rate-limit policies, versioning strategy
- **Use-case requirements** — specific banking functions needed (account linking, balance checks, transaction history, payment initiation, identity verification)
- **Security and compliance requirements** — encryption standards, authentication protocols (OAuth 2.0, mTLS), data residency constraints, SOC 2/ISO 27001 certifications [VERIFY which certifications the provider holds]
- **Integration context** — existing tech stack, middleware/aggregation layers, expected transaction volumes, latency tolerances
- **Commercial terms** — pricing model (per-call, per-connection, tiered), SLA commitments, contract term, data ownership clauses
- **Stakeholder priorities** — rank-ordered list of evaluation criteria (coverage, reliability, cost, time-to-integrate, regulatory alignment)

## Workflow

1. **Scope the evaluation** — Define which banking API functions are in scope (account aggregation, payments, lending data, KYC). Identify the target financial institutions and geographies. Confirm evaluation criteria weights with stakeholders.

2. **Assess functional coverage** — Map each API provider's endpoint catalog against required use cases. Document gaps (e.g., missing real-time balance, no support for certain institution types). Note FI coverage rates and whether connectivity uses direct API, screen-scraping, or hybrid methods.

3. **Conduct security review** — Evaluate authentication and authorization flows, token management, data encryption in transit and at rest, credential storage practices, and incident-response SLAs. Check for PCI DSS scope implications if payment card data is involved. [VERIFY PCI DSS applicability based on data flows]

4. **Evaluate reliability and performance** — Review uptime SLAs, historical availability data, rate limits, timeout behaviors, retry policies, and error-code granularity. Test sandbox endpoints for latency and response consistency where possible.

5. **Analyze regulatory alignment** — Confirm compliance with applicable open-banking standards (FDX in the US, PSD2/Berlin Group in Europe, CDR in Australia). Assess data-minimization capabilities and consumer consent management flows. [VERIFY regional regulatory frameworks]

6. **Model integration effort** — Estimate development time for SDK integration vs. raw REST calls. Identify dependencies on webhooks, batch processing, or asynchronous flows. Map migration risks if replacing an existing provider.

7. **Compare commercial terms** — Normalize pricing across vendors to a common unit (cost per API call, cost per connected account per month). Flag volume-discount thresholds, overage penalties, minimum commitments, and termination provisions.

8. **Synthesize findings and recommend** — Produce a weighted scorecard across functional, security, reliability, regulatory, and commercial dimensions. Highlight the top-ranked option with rationale and flag material risks for the runner-up.

## Output

The deliverable is a **Banking API Evaluation Report** containing:

- **Executive summary** — Recommended provider, key rationale, and critical caveats
- **Functional coverage matrix** — Use cases vs. provider capabilities (supported / partial / unsupported)
- **Security assessment summary** — Authentication model, certifications held, data-handling practices, identified gaps
- **Reliability scorecard** — Uptime SLA, observed latency, rate limits, error-handling quality
- **Regulatory alignment table** — Applicable standards mapped to provider compliance status
- **Integration effort estimate** — LOE in engineering weeks, key technical dependencies, migration risks
- **Commercial comparison** — Normalized pricing, SLA terms, contract flexibility
- **Weighted scorecard** — Final ranking with dimension-level scores and aggregate recommendation
- **Risk register** — Material risks per provider with mitigation recommendations

## Quality Checks

- Every capability claim is traceable to provider documentation or sandbox testing — no unsourced assertions
- Security review covers authentication, encryption, data residency, and incident response at minimum
- Pricing comparison uses a consistent normalization basis and states assumptions (projected volume, connection count)
- Regulatory compliance items are tagged with [VERIFY] where jurisdiction-specific validation is needed
- Integration estimates account for both happy-path and error-handling development
- Scorecard weights match the stakeholder-agreed criteria from Step 1
- Report flags any provider that lacks SOC 2 Type II or equivalent independent audit as a material risk
