Create an invoice with sevdesk

[schnipo]

Could somebody help me to create a valid invoice with sevdesk? I only get error and it seems my fault somehow.

Using the community node, I get the wrong format for the “Save Invoice Positions” field. Using http-node I have the same problem. Could somebody send me an example cURL for an invoice with 2 positions or an example for the community node?

Thanks very much in advance.

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

I took a look at the docs and I am not sure what “invoice model” is. You need to pass that and it’s an object.

cmmd + f didn’t show it anywhere else in the docs.

If you can reply back with what that is I can help you put the request together

Thanks for your offer to help!

The description of Models are here: sevDesk - API

Using the http-node would be also fine for me, but I started with the sevdesk community node.

When I use this in “Save Invoice Positions”:

    {
      "unity": {
        "id": 1
      },
      "taxRate": 19,
      "objectName": "Position 1",
      "quantity": 2,
      "price": 50
    },
    {
      "unity": {
        "id": 1
      },
      "taxRate": 7,
      "objectName": "Position 2",
      "quantity": 1,
      "price": 80
    },
    {
      "unity": {
        "id": 1
      },
      "taxRate": 19,
      "objectName": "Position 3",
      "quantity": 3,
      "price": 25
    }
  ]

I get

Error code

400

I treid the same with the http-node

this ist the body:

{
  "invoice": {
    "objectName": "Invoice",
    "invoiceNumber": "DRAFT-2023-001",
    "invoiceDate": "2023-05-16",
    "contact": {
      "id": 76147211
    },
    "invoiceType": "RE",
    "currency": "EUR"
  },
  "positions": [
    {
      "unity": {
        "id": 1
      },
      "taxRate": 19.0,
      "objectName": "Position 1",
      "quantity": 2,
      "price": 50
    },
    {      
      "unity": {
        "id": 1
      },
      "taxRate": 7.0,
      "objectName": "Position 2",
      "quantity": 1,
      "price": 80
    },
    {
      "unity": {
        "id": 1
      },
      "taxRate": 19.0,
      "objectName": "Position 3", 
      "quantity": 3,
      "price": 25
    }
  ],
  "taxSet": {
    "id": 89398,
    "objectName": "TaxSet"
  }
}

this is the error:
