Chime API Integration Service — Open Finance / Protocol Analysis

Standard Deliverables

• Protocol analysis report (session, encryption, API paths, certs and signing points)
• OpenAPI / Swagger specifications and sample requests
• Runnable backend sources (Node.js / Python) with deployment guidance
• Automated test scripts, sample data and test cases
• Compliance & privacy guidance (data retention, logging, user consent records)

Interface Example: Get User Transactions (Pseudo-code)

// POST /api/v1/chime/transactions
Content-Type: application/json
Authorization: Bearer <ACCESS_TOKEN>

{
  'user_id': 'chime_user_123',
  'from': '2025-09-01T00:00:00Z',
  'to': '2025-09-30T23:59:59Z',
  'page': 1,
  'page_size': 200
}

Response: {
  'status': 'OK',
  'page': 1,
  'transactions': [
    { 'tx_id':'TX1001','date':'2025-09-10','amount':-45.50,'merchant':'Coffee Shop','type':'DEBIT' },
    { 'tx_id':'TX1002','date':'2025-09-11','amount':1200.00,'merchant':'Payroll','type':'CREDIT' }
  ]
}

Key Security & Permissions Considerations

Mobile app permissions (e.g., reading call logs or screening roles) are often used for fraud detection and caller identification prompts. We can provide minimal-permission alternatives and privacy-compliance recommendations to reduce review risk.

Core Advantages

• Cross-platform protocol adaptation: Android / Wear OS / hardware interactions
• Many years of financial and payments experience, familiar with compliance and regulatory requirements
• Deliver production-ready source code plus comprehensive API docs and test suites
• Emphasis on privacy: minimal permissions and logging/consent guidance
• Transparent pricing: starting at $300, pay on acceptance

Typical Integration Scenarios

Account verification and onboarding (encrypted SMS / VMN), ATM QR withdrawals and Beacon withdrawals, Quick Loan application and approval, Wear OS payment entry, virtual/physical card management and remote freeze/unfreeze, and transaction notifications and approvals chain (enterprise/individual).

API Integration Quick Guide

1. Provide the target app name (e.g., Chime) and the expected scenarios (e.g., transaction capture / early pay / reconciliation).
2. Protocol analysis phase (2-5 business days): capture authorization flow, session maintenance, encryption and signing points, key API paths.
3. Interface design & simulation (1-3 days): define OpenAPI, error codes and rate-limiting strategies.
4. Development & testing (3-10 days): deliver runnable services, unit tests, integration tests and sample scripts.
5. Deployment & delivery (1-3 days): provide deployment scripts, operations guidance, docs and sample SDK.

Note: If you need to interface with third-party banks or regulators, approvals and compliance reviews may extend the delivery timeline.
