Hi @TheTweakyTales ,
this node has a really strange design to POST invoice data!
As @barn4k already mentioned it is not possible to add a JSON-array.
But it is possible to do it like “hardcoded”:
You can add several item-lines in this node manually and map them with your source-JSON item by item. (you have to add as much item lines as you ever expect to get + 1.)
{
“nodes”: [
{
“parameters”: {
“jsCode”: “const lineItems = [\n {\n item: 1,\n product: \“TSL-001\”, // Use Project ID as Product name\n description: \“Rushil Ranade Speaker 9/9/25\”,\n quantity: 1,\n unit_cost: 60\n },\n {\n item: 2,\n product: \“2TSL-001\”, // Use Project ID as Product name\n description: \“2Rushil Ranade Speaker 9/9/25\”,\n quantity: 2,\n unit_cost: 260\n }\n];\n\n// Return as JSON\nreturn [{ json: { line_items: lineItems } }];\n”
},

Another option is using a http-node to make an custom api request.
This should make it possible to pass an array with line items.
