## Migration Required

This endpoint has been replaced by the v1 Collections Tier-N API. Please migrate to the new endpoint:

### Replacement Endpoint

| Old Endpoint | New Endpoint | Purpose |
|--------------|--------------|---------|
| `GET /public/v2/network/{collectionId}/tree-graph` | `GET /public/v1/collections/{collectionId}/tier-n/data` | Get collection-based supplier graphs |

---

## Why Migrate?

The v1 Collections Tier-N API provides significant improvements:

### 1. Enhanced Functionality
- **v2**: Basic tree graph with limited configuration
- **v1 Tier-N**: Advanced filtering through collection settings
- **v1 Tier-N**: Configurable data sources (customs, media, predictions)
- **v1 Tier-N**: Better control over scope (private, shared, public targets)

### 2. Better Performance
- **v1 Tier-N**: Optimized queries for large collections
- **v1 Tier-N**: More efficient data retrieval

### 3. Improved Documentation
- Comprehensive examples for all endpoints
- Detailed error response documentation
- Clear parameter descriptions

## Quick Migration Guide

### Step 1: Update Endpoint URL

**Before:**
```http
GET /public/v2/network/123/tree-graph?tierLevel=3
```

**After:**
```http
GET /public/v1/collections/123/tier-n/data?tierLevel=3
```

### Step 2: Update Response Parsing

**Before:** Parse `PublicTreeTargetV2` structure

**After:** Parse `PublicTierNCollectionGraphEntry` structure (different format)

---

**Required Permissions**: `ACCESS_PUBLIC_TREE_GRAPH` and `READ` on the collection

**Performance Impact**: High

For detailed API reference and examples, see the v1 Collections Tier-N API documentation.
