i send this type of object in CREATE CUSTOM ORDER on https://sandbox.dev.clover.com/v3/merchants/merchantsID/orders

{

"orderType": {

"taxable": "false",

"isDefault": "false",

"filterCategories": "false",

"isHidden": "false",

"isDeleted": "false",

"id": "933GNCVHQFM4T",

"labelKey": "dine-in",

"currency": "USD",

"customers": [

{

"id": "B0852SWPKDV3C",

"firstName": "Test",

}

"emailAddresses": [

}

"phoneNumbers": [

}

"total": 1000,

"isTokenBasedTx": "false",

"emergencyFlag": "false"

}

"isRevenue": "false",

"name": "pizza",

"price": 1000

}

]

}

but when i send this request it will give only

 
                 {"href": "https://sandbox.dev.clover.com/v3/merchants/PKST1890A6671/orders/ZG761A2N9S12P", "id": "ZG761A2N9S12P", "currency": "USD", "orderType": {"id": "933GNCVHQFM4T"}, "taxRemoved": false, "isVat": false, "manualTransaction": false, "groupLineItems": true, "testMode": false, "createdTime": 1712063787000, "clientCreatedTime": 1712063787000, "modifiedTime": 1712063787000} 
                

why it can't take customer details and line item in create custom order API?
