- Page in the portal: https://developers.rivr.io/errors/amount_zero_or_negative
- Try it: `GET https://developers.rivr.io/errors/simulate/amount_zero_or_negative` answers with the code's exact wire form; `?succeedAfter=N&attempt=K` gives a 200 once `attempt` passes `N`

## What it means

The order's total, worked out from the order lines, is zero or negative.

## What your system does

Check `quantity`, `unitPriceExclVat` and `discountExclVat` on the lines, and send the order again with the same order id.

## Is it worth retrying?

No, not without changing the call.

`retryWhen`: `after_fix`. Change the request first, as the code's page says: a value, the token, a header or a new key. Then send it.

## Did anything happen?

`outcome`: `none`. **It did not happen.** This call did not do what you asked for and changed nothing else that you can see or that concerns money. Where the code has an `outcomeNote`, it takes precedence.

## Example: /api/public

```http
HTTP/1.1 422 Unprocessable Entity
Content-Type: application/json

{
  "propertyName": "Amount",
  "message": "Amount must be greater than 0",
  "errorCode": "amount_zero_or_negative",
  "code": "amount_zero_or_negative",
  "type": "https://developers.rivr.io/errors/amount_zero_or_negative"
}
```

The `title`, `detail`, `message` and `error_description` texts are exactly as the API writes them today.
