🎯 How to Use​

Example 1: Default Behavior​

# No changes needed - backward compatible
GET /sales/123/pdf

# Uses sale.template.html from files (legacy)

Example 2: Custom Business Template​

# 1. Upload custom template
POST /pdf/templates/upload
{
  "name": "Acme Corp Receipt",
  "documentType": "sale",
  "businessId": "acme-uuid",
  "isDefault": true,
  "htmlTemplate": "..."
}

# 2. Generate with location resolution
GET /sales/123/pdf?useLocationTemplate=true

# Uses Acme's default template automatically

Example 3: Thermal Receipt​

# 1. Upload 80mm thermal template
POST /pdf/templates/upload
{
  "templateFormat": "receipt_thermal_80mm",
  "pageConfig": {
    "width": 80,
    "isContinuous": true,
    "margins": { "top": 2, "right": 2, "bottom": 2, "left": 2 }
  }
}

# 2. Use directly
GET /sales/123/pdf?templateId=thermal-template-uuid

# Perfect for thermal printers!

🧪 Test the Integration​

# Test 1: Default (should work as before)
curl http://localhost:4000/sales/SALE_ID/pdf \
  -H "Authorization: Bearer TOKEN"

# Test 2: With template override  
curl "http://localhost:4000/sales/SALE_ID/pdf?templateId=TEMPLATE_UUID" \
  -H "Authorization: Bearer TOKEN"

# Test 3: With location resolution
curl "http://localhost:4000/sales/SALE_ID/pdf?useLocationTemplate=true&locationId=LOCATION_UUID" \
  -H "Authorization: Bearer TOKEN"

# Test 4: Purchase (same pattern)
curl "http://localhost:4000/purchases/PURCHASE_ID/pdf?useLocationTemplate=true" \
  -H "Authorization: Bearer TOKEN"
