error "$message": "purchase_invoice[invoice_lines] is invalid"

[Aladin SALEH]

I'm  trying to learn the sage api
I've tried to make a POST request for create a purchase invoice
so I did as the documentation but i get this error message.
 "$message": "purchase_invoice[invoice_lines] is invalid"
and I don't know why.

Can someone help me ?

Hi Aladin,

This is most likely because you are passing the attributes and values as query params. You need to ensure you build a JSON body as per our API reference, passing the values accordingly, along with a header of Accept: application/json:

Purchase Transactions | Sage Developer

{
  "purchase_invoice": {
  "contact_id": "string",
  "date": "2019-08-24",
  "due_date": "2019-08-24",
  "reference": "string",
  "total_quantity": 0,
  "net_amount": 0,
  "tax_amount": 0,
  "total_amount": 0,
    "invoice_lines": [
    ...
    ],
  	"tax_analysis": []
  }
}

Once you've had a look at the guide I've linked above it should make sense. Let me know if you still have any issues.
