Itemized order info with AIM

[txm1004]

Hi all,

We're having a problem with the itemized order info using the AIM method. On page 22 of the AIM developer guide is a snippet of sample code - we have copied this snippet into our test page and it always results in an error (code 270: Line item is invalid).

The code is:

x_line_item=item1<|>golf balls<|><|>2<|>18.95<|>Y&x_line_item=item2<|>golf bag<|>Wilson golf carry bag, red<|>1<|>39.99<|>Y&
x_line_item=item3<|>book<|>Golf for Dummies<|>1<|>21.99<|>Y&

I contacted Auth.net and told them their sample code results in an error but their customer service rep disagreed...hmmm, ok. 

If we change the code to pass a single item only it works fine. Does anyone know how to fix this sample code? I've tried just about all I can think of and am close to pulling out my hair!

Thanks,

Tom

Are you urlencoding the parameters? Please provide a snippet of how you're passing the data to Authorize.Net.

Thank You!

I've hardcoded it this way for testing and it always results in this error 270:

x_line_item="item1<|>golf balls<|><|>2<|>18.95<|>Y&x_line_item=item2<|>golf bag<|>Wilson golf carry bag, red<|>1<|>39.99<|>Y&x_line_item=item3<|>book<|>Golf for Dummies<|>1<|>21.99<|>Y&"

post_values.Add "x_line_item", x_line_item

When I pass a single item like this one below it works just fine.

x_line_item = "item1<|>golf balls<|><|>2<|>18.95<|>Y"

Is there some typo I am not seeing?

Thank you!

I'm having the same problem.

If I use an HTML form with multiple hidden fields with name="x_line_item" it will take the additional items.

However using the sample vb.net code for AIM, or creating a post with the same data, they get rejected.

Can anyone make this work??

I'm glad that I'm not the only one having problems with Authorize.net's sample code...I thought I was going crazy. :smileysad:

The itemized order feature works fine for us when using SIM...or when using just 1 single item with AIM. But the sample code does not work for multiple items and AIM.

Does anyone have a suggestion? Or may someone from Authorize.net could chime in....

Thanks!

I was just chatting with Auth.net's customer support (thanks, Emily - you were really trying to help!)...

We tried several things:

• - it seems that there is an extra bracketed pipe in the sample code for item1 right after the string 'golf balls'...the other line items do not have this. I get the same error = 270 though when I remove the bracketed pipe from item1
• - there's a comma in the text field in item2...we tried removing that but it results in the same error = 270

I believe there's a bug in this feature and asked for escalation of this issue for a development review...I hope I will hear from auth.net soon. If/when I do I will update this post.

Does anyone have any other suggestions or possible solutions? I can't image that we're the first to run into this problem...

Thanks,

Tom

I'm attaching an updated copy of our AIM PHP sample code with a new section showing how to add line item details.  The most common error when adding line item details to our sample code is to simply add multiple x_line_item fields to the array. Because the sample code uses associative arrays, this will usually cause a duplicate key error or all but one of the items will simply be discarded.

In the above example, the most likely problem is actually the url_encode process itself.  I see that you avoided the error of duplicate keys by adding the whole url string with only one , unfortunately this presents a whole new error by urlencoding the ampersands in the string.  This results in them no longer being recognized as special characters dividing the multiple x_line_item values.

Please take a look at this new sample code and let me know if you have any questions.  I can provide the equivalent code for any of our AIM samples if needed.  If you do find this helpful, I will consider officially adding similar code to each of our available AIM sample code downloads.

Hi Trevor,

Thank you for the explanation...very helpful!

Yes, if possible I'd like to see a sample code for the line items details for ASP.

Can you post this here or update the sample code library?

Thanks,

Tom

Since you just said ASP, I'm going to assume that you are referring to ASP classic.  I've attached an updated version of the ASP classic code that adds in the line items.

Hi Trevor,

Fantastic! This works like a charm now! Thank you!

One more question though...I noticed you placed the line item code after the post_string has already been completely encoded. We're then looping over our shopping cart line items and add the line items with this code:

item = Count & "<|>" & RS("ItemCode") & "<|>" & RS("ItemName") & "<|>" & RS("ItemQuantity") & "<|>" & RS("ItemDiscountedPrice") & "<|>N"
	
post_string = post_string & "&x_line_item=" & Server.URLEncode(item)

We would also like to pass the line item info to the merchant receipt using this code:

merchant_field = "Item " & Count
merchant_field_value = RS("ItemCode") & " - " & RS("ItemName") & "  " & FormatCurrency(RS("ItemDiscountedPrice"))

post_values.Add merchant_field, merchant_field_value

Since the post_string has already been encoded I assume that we can't add these merchant_fields during the same loop and should add them prior to the encoding of the post_string, correct? Just want to make sure we're not doing an unnecessary loop over the shopping cart...

Again, thank you for your help!

Tom
