Bad Request from Shipping API

[cralls]

Hi,

Maybe you can see something wrong with my XML here? I've tried changing src/Order.php to ns2 and adding the other namespace for http://walmart.com/ like the partner api documentation says but then I saw the closed Issue on this where someone mentioned try using otherCarrier but nothing seems to work. I always get Bad Request back from the API.

<?xml version="1.0" encoding="UTF-8"?>
<ns3:orderShipment
    xmlns:ns3="http://walmart.com/mp/v3/orders">
    <ns3:orderLines>
        <ns3:orderLine>

            </ns3:orderLineStatuses>
        </ns3:orderLine>
    </ns3:orderLines>
</ns3:orderShipment>

I'm also unsure what the lineNumber should be? Where does that number come from? I'm assuming it would be 1 for the first product in the order then 2, 3 etc...

[fillup]

Hi @cralls the lineNumber should be the number from the order details of the order for the item shipping. Since an order can have multiple items/lines, each has a given number, so you want to make sure you are updating the shipping for each line appropriately. Your XML looks fine to me as far as I can tell. Can you show me the array you passed into the client to generate this?

Have you Acknowledged the order before attempting to ship it?

[cralls]

Thanks for such a quick reply. I'll try to pull an order and look for the lineNumber.

Here's the array I passed, I just copied it from the OrderTest.php and added my variables and yes the order is Acknowledged:

$orderXml = [ 
    'orderShipment' => [ 
        'orderLines' => [ 
            [ 
            'lineNumber' => 1,
                'orderLineStatuses' => [ 
                    [ 
                    'status' => 'Shipped',
                    'statusQuantity' => [ 
                        'unitOfMeasurement' => 'Each',
                        'amount' => number_format ( $item->getQtyOrdered (), 0 ) 
                    ],
                    'trackingInfo' => [ 
                        'shipDateTime' => date ( "Y-m-d" ) . 'T' . date ( "H:m:s" ) . 'Z',
                        'carrierName' => [ 
                            'carrier' => 'USPS' 
                        ],
                        'methodCode' => 'Standard',
                        'trackingNumber' => $tracknum->getNumber (),
                        'trackingURL' => 'https://tools.usps.com/go/TrackConfirmAction.action' 
                    ] 
                ] 
            ] 
        ] 
    ] 
] 
];

[solasus]

I'm seeing a the same issue here. Also tried switching between ns2

any thoughts....?

Here's the code I'm using to generate:

$movementDate = date('Y-m-d', $movementDateRaw).'T14:30:00.000Z';
$trackingNos = explode(',',$orders['trackingno']);

$client = new Order([
        'consumerId' => $app_consumerId,
        'privateKey' => $app_privateKey,
        'wmConsumerChannelType' => $app_walmartChannelType,             
        ], 
        Order::ENV_PROD  
        );

$purchaseOrderId = $orders['poreference'];
$order = [
    'orderShipment' => [
        'orderLines' => [
             [
                'lineNumber' => $orders['orderitemreference'],
                'orderLineStatuses' => [
                     [
                        'status' => 'Shipped',
                        'statusQuantity' => [
                            'unitOfMeasurement' => 'Each',
                            'amount' => $orders['movementqty']
                        ],
                        'trackingInfo' => [
                            'shipDateTime' => $movementDate,
                            'carrierName' => [
                                'carrier' => $orders['carriername']
                            ],
                            'methodCode' => 'Ground',
                            'trackingNumber' => $trackingNos[0],
                            'trackingURL' => 'https://www.ups.com',
                        ]
                    ]
                ]
            ]
        ]
    ]
];
// print_r($order);
$response = $client->ship($purchaseOrderId, $order);
print_r($response,true);

Here's the resulting xml

How did you get your xml line to include: standalone="yes"

where did you add that? and was it actually attempted against the api or did you just add here.

The reason I ask is that may be the key as it should tell the process to not be too depended on the DTD - whereas if that line is missing, then the default is "no" and it means strict adherence to a DTD.

[cralls]

Sorry, I was driving when I last replied. I added it to line 20 of A2X.php as follows:

    $this->xml = sprintf('<?xml version="%s" encoding="%s"

standalone="yes"?>', $version, $encoding);

The Walmart API Documentation Sample XML Request has that in there. I've sent it with and without and still get the 400 Bad Response from the API.

ah thanks for the clarification (and quick response).

I was leary to add the declaration there as some functions in the api spec seem to have it excluded (e.g. Refund order). Sounds like we're both trying a lot of things here. Hopefully @fillup might have some insight. Also, I've opened a ticket w/ WM support. Perhaps something will come of that.

[cralls]

No problem, I've opened a case with WM support too which usually isn't that helpful but perhaps they will be able to see what's wrong with our XML.

@cralls have you used something like Charles Proxy to inspect the request and full response to see if there is anything more informative in the response body about why the request was bad? I've wanted to update this SDK to capture the error responses better but haven't had the time. During development I used Charles Proxy pretty extensively though to watch everything and see what was happening.

[cralls]

@fillup I haven't but I will try it and see if I can come up with some more information for us and hopefully a fix too :)

@fillup I'm not sure the Charles Proxy is going to give us the info we need. It's only showing me the request/response between my browser and the apache web server, it's not going to show me the request/response between the web server and the API which is what we need to get at.

Interesting, that is definitely promising though! I have a couple questions: How did you decide what the linenumber would be? Also, curious what the xmlns:ns4 is coming from?

for the xmlns:ns4 ... I just got from the response example (directly below the request)

The line number we got on the Get all released orders method https://developer.walmartapis.com/#get-all-released-orders

[cralls]

Ok, so good news. It seems to be working for me too now. So before I send the tracking number I'm now grabbing the order and using the linenumber on the order rather than assuming it would be 1 for the first time 2 for the second item etc... For the order I tested the linenumber was in fact 1 for the first item on the order. It's interesting that you got a 36? At any rate, I'm sure that linenumber needs to match up to add the tracking number correctly so the final XML that works is as follows which is the same XML I posted before without the standalone="yes" part.

<!xml version="1.0" encoding="UTF-8"> <ns2:ordershipment xmlns:ns2="http://walmart.com/mp/v3/orders" xmlns:ns3="http://walmart.com/">

I haven't tested it. $schema = [ '/orderShipment' => [ 'namespace' => 'ns2', 'childNamespace' => 'ns2', ], '/orderShipment/orderLines' => [ 'sendItemsAs' => 'orderLine', ], '/orderShipment/orderLines/orderLine/orderLineStatuses' => [ 'sendItemsAs' => 'orderLineStatus', ], '@namespaces' => [ 'ns2' => 'http://walmart.com/mp/v3/orders', 'ns3' => 'http://walmart.com/' ], ]; *Casey Ralls* E-Commerce Manager | cralls@vectorns.com | 208.572.0468 | www.vectorns.com On Wed, Dec 21, 2016 at 9:08 AM, solasus wrote: > for the xmlns:ns4 ...

So I'm struggling to get this to work also. I continue to receive this error:

Here's my adjusted Order.php $shema array:

I've taken your advice to get the order before trying to push the tracking number as shown here:

$order = $client->get([
    'purchaseOrderId' => $order_num
]);

and this is the order that I retrieve:

Array ( 
    [statusCode] => 200 
    [purchaseOrderId] => Customer PO ID 
    [customerOrderId] => Customer Order ID 
    [customerEmailId] => ptdixiegal@aol.com 
    [orderDate] => 2017-02-23T23:30:50.000Z 
    [shippingInfo] => Array ( 
        [phone] => Customer Phone Number 
        [estimatedDeliveryDate] => 2017-03-09T07:00:00.000Z 
        [estimatedShipDate] => 2017-02-28T07:00:00.000Z 
        [methodCode] => Value 
        [postalAddress] => Array ( 
            [name] => Customer Name
            [address1] => Customer Address 
            [city] => Customer City 
            [state] => Customer State
            [postalCode] => Customer ZIP Code 
            [country] => USA 
            [addressType] => RESIDENTIAL 
        ) 
    ) 
    [orderLines] => Array ( 
        [orderLine] => Array ( 
            [lineNumber] => 1 
            [item] => Array ( 
                [productName] => Product Name Is Here 
                [sku] => GH2 
            ) 
            [charges] => Array ( 
                [charge] => Array ( 
                    [chargeType] => PRODUCT 
                    [chargeName] => ItemPrice 
                    [chargeAmount] => Array ( 
                        [currency] => USD 
                        [amount] => 11.45 
                    ) 
                ) 
            ) 
            [orderLineQuantity] => Array ( 
                [unitOfMeasurement] => EACH 
                [amount] => 1 
            ) 
            [statusDate] => 2017-02-23T23:46:24.000Z 
            [orderLineStatuses] => Array ( 
                [orderLineStatus] => Array ( 
                    [status] => Acknowledged 
                    [statusQuantity] => Array ( 
                        [unitOfMeasurement] => EACH 
                        [amount] => 1 
                    ) 
                ) 
            ) 
        ) 
    ) 
) 

I use the lineNumber from the get call as the lineNumber for the ship call. Any ideas on why it's not working?

[solasus]

The WM api (or perhaps Guzzle, or most likely my own ignorance is to blame) ... is not well documented and/or handles errors poorly. It seems that just about anything results in a "400 [reason phrase] Bad Request" error. We found that if you attempt to post a second time to the same order that you'll see this error. Because we run batch processes these errors would kill the process in the middle - especially if someone updated an order or even a part of an order mid-day. To get around this I commented out a couple of lines in /vendor/guzzlehttp/command/src/AbstractClient.php around ln 171

//        return new $cn(
//            "Error executing command: " . $transaction->exception->getMessage(),
//            $transaction,
//            $transaction->exception
//        );

hope this helps...

@solasus That's interesting that you get the Bad Request for posting multiple times. That would explain why I had such a difficult time getting this going and then all of a sudden the next few orders mysteriously were working.

@michaeljberry I guess the only part I haven't posted is my ship call so here's that for you. Hope it helps!

$orderXml = [ 
    'orderShipment' => [ 
        'orderLines' => [ 
            [ 
            'lineNumber' => $lineNumber['lineNumber'],
                'orderLineStatuses' => [ 
                    [ 
                        'status' => 'Shipped',
                        'statusQuantity' => [ 
                            'unitOfMeasurement' => 'Each',
                            'amount' => $lineNumber['qty']
                        ],
                        'trackingInfo' => [ 
                            'shipDateTime' => date ( "Y-m-d" ) . 'T' . date ( "H:m:s" ) . 'Z',
                            'carrierName' => [ 
                                'carrier' => 'USPS' 
                            ],
                            'methodCode' => 'Standard',
                            'trackingNumber' => $tracknum->getNumber (),
                            'trackingURL' => 'https://tools.usps.com/go/TrackConfirmAction.action' 
                        ] 
                    ] 
                ] 
            ] 
        ] 
    ] 
];
try {
    $response = $orders->ship ( $purchaseOrderId, $orderXml );
} catch (Exception $e) {
    Mage::log($e->getMessage());
}

Sorry I disappeared for a while, although not sure I could have added much. Glad you guys were able to figure it out. With the error handling causing the 400 it might be best to post each order shipment status individually to be able to catch when it happens.
