Invalid JSON data in request body

[Mingo07-dev]

I'm trying to create a valid JSON from zero following the guide https://developers.fattureincloud.it/docs/guides/invoice-creation , but I'm getting this error:

"error": {
    "message": "Invalid JSON data in request body.",
    "validation_result": null
  }

What I 'm missing, one or more mandatory properties, or am I just writing something wrong?
Moreover I don't understand the difference between due_date and payment_terms inside payment_list, are they the ways to express the same thing?

Here's my JSON:

{
    "data": {
        "entity": {
            "name": "Mario Rossi",
            "first_name": "Mario ",
            "last_name": "Rossi",
	    "tax_code": "RSSMAR99R20G273F",
	    "address_street": "Via Libertà",
	    "address_postal_code": "1",
	    "address_city": "Palermo",
	    "address_province": "PA",
             "country": "Italia",
        },
        "type": "invoice",
        "numeration": "FT-2023",

        "items_list":{
            "name": "NomeTrattamento",
            "net_price": 30,
            "vat": {
                "id": 45
            },
            "qty": 1
        },
        "payments_list": [
            {
                "amount": 30,
                "due_date": "2023-01-01",
                "status": "not_paid",
                "payment_account": {
                    "id": 1127896
                }
            }
        ],
        "extra_data": {
            "ts_communication": true,
            "ts_pagamento_tracciato": true,
            "ts_tipo_spesa": "SR" 
        }
    }
}

Hi @Mingo07-dev, the error you are receiving is due to a formal error in the json (in this case "country": "Italia", shouldn't contain the trailing comma), also when you are missing a mandatory property in the request body the error that gets returned contains exactly which fields are missing.

About the due_date and payment_terms question, actually the due_date field is mandatory even if payment_terms is specified (ideally the due_date could be automatically calculated in this case, but it doesn't work like that now), in fact the payment_terms field is there only if you want to keep track of them.

Thanks,
Emanuele.

Thank you, it works by deleting the comma and I also forgot that items_list must be an array of objects while it was an object

Hi @Mingo07-dev
We suggest using one of our SDKs to avoid this kind of error when possible.
Have you checked if one of those could be of interest?

Thanks

Yes, I'm using the PHP SDKs, but I was testing in the API reference to undersand how to compose my PHP array with just the fields that I need
