transactionRequest errors on array of lineItems

[Critter]

I didn't know where else to ask this.

The schema says that transactionRequestType takes <xs:element name="lineItems" type="anet:ArrayOfLineItem" minOccurs="0"/> an array of lineItem.

The example on the documention site only shows 1 item being passed in.

"lineItems": {
    "lineItem": {
        "itemId": "1",
        "name": "vase",
        "description": "Cannes logo",
        "quantity": "18",
        "unitPrice": "45.00"
    }
}

Wouldn't an array of lineitems be like this:

"lineItems": [
        {
          "lineItem": {
            "itemId": "10077",
            "name": "Fake name for something",
            "description": "dog.com",
            "quantity": 1,
            "unitPrice": "399.00"
          }
        },
        {
          "lineItem": {
            "itemId": "10077",
            "name": "fake name for something",
            "description": "cat.com",
            "quantity": 1,
            "unitPrice": "399.00"
          }
        }
      ]

This throws back an error saying that lineItems is an invalid element.

I'm creating my lineItems like this:

public function getLineItems()
{
	$result = [];
	foreach ($this->lineItems as $lineitem) {
		$arr = array(
			"lineItem" => array(
				"itemId" => $lineitem->itemId,
				"name" => mb_strimwidth($lineitem->name,0,31,''),
				"description" => $lineitem->description,
				"quantity" => $lineitem->quantity,
				"unitPrice" => $lineitem->unitPrice
			)
		);
		$result[] = $arr;
	}
	return $result;
}

and using them in my request like this:

public function generatePaymentRequest()
{
  $result = array(
    "createTransactionRequest" => array(
      "merchantAuthentication" => array(
        "name" => $this->authnet->name,
        "transactionKey" => $this->authnet->transactionkey
      ),
      "refId" => $this->refId,
      "transactionRequest" => array(
        "transactionType" => $this->transactionType,
        "amount" => $this->amount,
        "profile" => array(
          "customerProfileId" => $this->customerProfileId,
          "paymentProfile" => array(
            "paymentProfileId" => $this->paymentProfileId
          ),
        ),
        "lineItems" => $this->getLineItems() <-----<
      ),
    )
  );
  return json_encode($result);
}

Hi @Critter

Can you refer to this issue #116 ? It might have the answer you are looking for.

[Critter]

I was hopeful, but I'm still having issues.

This is a valid request according to the docs. I've run this with my data, and it's created a 2-lined order

{
  "createTransactionRequest": {
    "merchantAuthentication": {
      "name": "zzzzzzz",
      "transactionKey": "zzzzzzz"
    },
    "refId": "xnumber-ref",
    "transactionRequest": {
      "transactionType": "authCaptureTransaction",
      "amount": 798,
      "profile": {
        "customerProfileId": "8675309",
        "paymentProfile": {
          "paymentProfileId": "48595683"
        }
      },
      "lineItems": {
        "lineItem" : {
          "itemId": "10077",
          "name": "Yearly Subscription",
          "description": "dog.com",
          "quantity": 1,
          "unitPrice": "399.00"
        },
        "lineItem" : {
          "itemId": "10077",
          "name": "Yearly Subscription",
          "description": "cat.com",
          "quantity": 1,
          "unitPrice": "399.00"
        }
      }
    }
  }
}

The problem is, is that it's not valid JSON, if you try to validate it you get a SyntaxError: Duplicate key 'lineItem' on line 25

validated JSON would have the lineitems like this:

{
  "createTransactionRequest": {
    "merchantAuthentication": {
      "name": "zzzzzzz",
      "transactionKey": "zzzzzzz"
    },
    "refId": "xnumber-ref",
    "transactionRequest": {
      "transactionType": "authCaptureTransaction",
      "amount": 798,
      "profile": {
        "customerProfileId": "8675309",
        "paymentProfile": {
          "paymentProfileId": "48595683"
        }
      },
      "lineItems": [
        {
          "itemId": "10077",
          "name": "Yearly Subscription",
          "description": "dog.com",
          "quantity": 1,
          "unitPrice": "399.00"
        },
        {
          "itemId": "10077",
          "name": "Yearly Subscription",
          "description": "cat.com",
          "quantity": 1,
          "unitPrice": "399.00"
        }
      ]
    }
  }
}

I agree that this is not valid JSON, depending on the validator you used. We have taken certain liberties with the JSON validation to ensure that this works in our context.

[Critter]

Something should reflect this somewhere, though, no? Or at least the JSON example should show more than 1 lineitem since it doesn't match with the schema.

[gnongsie]

Thank you for the suggestion. I'll relay that information to the relevant team to have it documented in some way so that developers are not inconvenienced.
