Angel One — API Integration for Trading & Investing Apps OpenFinance Solution

Standard Deliverables

• OpenAPI / Swagger interface specifications
• Protocol & authorization flow analysis (OAuth2, Session, Signatures)
• Runnable backend source code (Node.js / Python) with deployment notes
• Automation tests, Postman collections and integration test plans
• Compliance guidance (data minimization, logs, consent records)

Example: Place Order & Query (pseudo-code)

// Example: place a trade order (REST)
POST /api/v1/angelone/orders
Authorization: Bearer 
Content-Type: application/json

{
  "account_id": "demat:12345",
  "symbol": "RELIANCE",
  "side": "BUY",
  "type": "LIMIT",
  "price": 2580.5,
  "quantity": 10
}

Response:
{
  "order_id":"ORD-20251020-0001",
  "status":"ACKNOWLEDGED",
  "created_at":"2025-10-20T09:22:11Z"
}

WebSocket market data subscription (pseudo-code)
CONNECT wss://api.angelone.example/market
SUBSCRIBE {"topic":"tick.RELIANCE"}

Advanced Enhancements

Tenant-aware API gateway rules, rate limiting/fault tolerance, market data caching layer, and regulatory reporting transformers (compliance auditing) can be delivered on demand.

Core Benefits

• Rapidly expose member payments, bills, and rewards data via a standard API
• Privacy-first: only sync minimum data with user consent records
• Enterprise-grade audit, regression testing, and compliance guidance
• Supports multiple deployment modes: on-premise, client network, or serverless

Recommended Integration Architecture

A microservices approach:
- Identity & Authorization (OAuth2 / OIDC)
- Market data proxy (WebSocket cache + REST history)
- Trade gateway (idempotent, retry, callback reliability)
- Audit & Compliance modules (event logs, encrypted storage)

Step 1 — Provide Requirements & Authorization Scope

1. Specify target features (e.g., order, reconciliation, market data export).
2. Provide test accounts or corporate credentials; if needed, we perform protocol analysis under authorized scope.
3. Define compliance boundaries and data retention policies (NDA optional).

Step 2 — Analysis & PoC (2-5 days)

• Capture & analyze protocols with authorization granted (privacy & compliance respected).
• Reproduce authorization flow (OAuth / Session / Token refresh / CSRF signing).
• Deliver PoC interfaces (mock + minimal runnable implementation) for client validation.

Step 3 — Development & Delivery (3-12 days)

• Implement stable API layer and SDK (retry, idempotency, rate limiting).
• Provide OpenAPI docs, Postman collections and integration tests.
• Support minor adjustments within a week; complex integrations may require longer timelines.
