# DhanHQ MCP Server - Official API Specification Compliance
## ✅ Implementation Complete
The MCP server has been fully updated to comply with **official DhanHQ API v2.0 documentation** specifications.
### What Was Updated
#### 1. API Endpoints (12 Updated)
All order and trade endpoints now use `/v2/` prefix:
- ✅ POST `/v2/orders` - Place order
- ✅ PUT `/v2/orders/{orderId}` - Modify order
- ✅ DELETE `/v2/orders/{orderId}` - Cancel order
- ✅ GET `/v2/orders` - Order book
- ✅ GET `/v2/orders/{orderId}` - Get order by ID
- ✅ GET `/v2/orders/external/{correlationId}` - Get order by correlation ID
- ✅ GET `/v2/trades` - Trade book
- ✅ GET `/v2/trades/{orderId}` - Get order trades
- ✅ POST `/v2/super/orders` - Place super order
- ✅ PUT `/v2/super/orders/{orderId}` - Modify super order
- ✅ DELETE `/v2/super/orders/{orderId}/{leg}` - Cancel super order leg
- ✅ GET `/v2/super/orders` - Super order book
#### 2. Enum Values (Corrected)
Updated to match official specification:
**Product Types:**
```
CNC | INTRADAY | MARGIN | MTF | CO (Cover Order) | BO (Bracket Order)
```
**Order Types:**
```
LIMIT | MARKET | STOP_LOSS | STOP_LOSS_MARKET
```
**Validity:**
```
DAY | IOC (Immediate or Cancel)
```
#### 3. Request Fields (Added)
New optional fields supported per official spec:
- `disclosedQuantity` - Visibility limit for order (min 30% of quantity)
- `afterMarketOrder` - Place order after market hours
- `amoTime` - AMO timing (PRE_OPEN | OPEN | OPEN_30 | OPEN_60)
- `boProfitValue` - Bracket Order profit target
- `boStopLossValue` - Bracket Order stop loss value
#### 4. Type Definitions (Updated)
All TypeScript interfaces now match official API:
- `PlaceOrderRequest` - 11 fields now supported (including new optional fields)
- `ModifyOrderRequest` - Updated with official parameters
- `PlaceSuperOrderRequest` - Official enum values
- All request/response types align with DhanHQ v2 API
