The element transactionRequest has invalid child element lineItems

[electricodeapi2]

This is the JSON that I send:

{
    "createTransactionRequest": {
        "merchantAuthentication": {
            "name": "test",
            "transactionKey": "test"
        },
        "refId": "0000",
        "transactionRequest": {
            "transactionType": "authCaptureTransaction",
            "amount": "100.00",
            "payment": {
                "opaqueData": {
                    "dataDescriptor": "COMMON.ACCEPT.INAPP.PAYMENT",
                    "dataValue": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
                }
            },
            "lineItems": [
                {
                    "lineItem": {
                        "itemId": "item1",
                        "name": "item1",
                        "description": "item1",
                        "quantity": "1",
                        "unitPrice": "10"
                    }
                },
                {
                    "lineItem": {
                        "itemId": "item2",
                        "name": "item2",
                        "description": "item2",
                        "quantity": "1",
                        "unitPrice": "10"
                    }
                },
                {
                    "lineItem": {
                        "itemId": "item3",
                        "name": "item3",
                        "description": "item3",
                        "quantity": "1",
                        "unitPrice": "10"
                    }
                },
                {
                    "lineItem": {
                        "itemId": "item4",
                        "name": "item4",
                        "description": "item4",
                        "quantity": "1",
                        "unitPrice": "10"
                    }
                }, {
                    "lineItem": {
                        "itemId": "item5",
                        "name": "item5",
                        "description": "item5",
                        "quantity": "1",
                        "unitPrice": "10"
                    }
                }
            ],
            "userFields": {
                "userField": [
                    {
                        "name": "custom_data_1",
                        "value": "1"
                    }, {
                        "name": "custom_data_2",
                        "value": "2"
                    }
                ]
            }
        }
    }
}

Can someone explain what's wrong?

Is it the "[ ]" (braces).  I think it only curly braces an lineitems and brace lineItem? i mainly use XML.

[kabutotx]

Yep. See getTransactionDetailsResponse example in the API Reference.

lineItem will be the array with brace.

Thank you for your answer,

You are right and I need to change the square brackets,

The issue now is how do I do it using javascript,

I have multiple inputs related to the lineitems and the "JSON.stringify" generate it automatically,

Is there another way to do it?

[kabutotx · Accepted solution]

Maybe this example will help?

var obj = {};
obj.lineItems = {};
obj.lineItems.lineItem = [ {itemId: "1", name: "one"}, {itemId: "2",name: "two"}, {itemId: "3",name: "three"} ];
var myJSON = JSON.stringify(obj);

I had to change it a little bit but it actually works,
I'm suprised, it seems that they want the wanted like this (with lineItem for each set):

"lineItems": {
    {
        "lineItem": {
            "itemId": "item1",
            "name": "item1",
            "description": "item1",
            "quantity": "1",
            "unitPrice": "10"
        }
    },
    {
        "lineItem": {
            "itemId": "item2",
            "name": "item2",
            "description": "item2",
            "quantity": "1",
            "unitPrice": "10"
        }
    }
},

While yours generate this:

    "lineItems": {
        "lineItem": [
            {
                "itemId": "1",
                "name": "one",
                "description": "desc1",
                "quantity": "1",
                "unitPrice": "11.00"
            },
            {
                "itemId": "2",
                "name": "two",
                "description": "desc2",
                "quantity": "1",
                "unitPrice": "12.00"
            },
            {
                "itemId": "3",
                "name": "three",
                "description": "desc3",
                "quantity": "1",
                "unitPrice": "13.00"
            }
        ]
    },

This is what I changed:

var lineItems = {};
lineItems.lineItem = [ {itemId: "1", name: "one", description: "desc1", quantity: "1", unitPrice: "11.00"}, {itemId: "2",name: "two", description: "desc2", quantity: "1", unitPrice: "12.00"}, {itemId: "3",name: "three", description: "desc3", quantity: "1", unitPrice: "13.00"} ];
var myJSON = JSON.stringify(lineItems);

Thank you!
