Validations line item property

The _validations line item property is a JSON-encoded object that Supercycle’s cart validation reads to enforce rules at checkout. Several validations merge into one object, and only the keys relevant to that line item are present.

Example

{
  "membership": { "credits": 5 },
  "required_variant": { "id": 987654, "per_line": 1 },
  "quantity": { "max": 3 },
  "uniformity": { "key": "rental_start", "value": "2025-01-01" }
}
