When a shopper creates a purchase list, it is available in all site and account contexts for consumer commerce or account based-commerce, however, you can specify specific sites and/or accounts.

Issue a POST request to /ccstore/v1/purchaseLists. For example:

{
  "name":"Purchase List 1",
  "description":"Purchase List",
  "siteId":"siteUS",
  "accountId":"or-100001",
    "items": [{
    "productId":"Product_18Cxi",
    "catRefId": "Sku_18Dxi",
    "quantityDesired" : 25
  },
{
    "productId":"Product_5Cx",
    "catRefId": "Sku_5Cxy",
    "quantityDesired" : 30
  }
]
}
