      {"size": "11", "price": 4800}
    ]
  }
}

Validation Rules

Price Minimum

All listings must have a minimum price of 250 baht.

Quantity Limits

Quantity must be between 1 and 99 per listing.

No Duplicates

You cannot create multiple listings for the same SKU+size with different prices in a single request.

Common Errors

Error	Cause	Solution
Price too low	Price < 250	Set price >= 250 baht
Invalid quantity	Quantity outside 1-99	Use quantity 1-99
Listing not found	Invalid listing_id	Verify listing exists and belongs to you
Cannot edit sold listing	Listing already sold	Only active listings can be edited

Best Practices

1. Check lowest price first - Price competitively to sell faster
2. Use accurate SKUs - Match SASOM's product catalog exactly
3. Keep quantity updated - Cancel or update listings when stock changes
4. Set realistic prices - Market-aligned prices sell faster
