Why is txn_type unexpectedly "cart" instead of "web_accept"?

[LeonardChallis]

 We have standard form integration to take PayPal payments. We also have a notification url setup for IPN. We get "web_accept" txn_type entries in these and use that to distinguish it from anything else like a dispute getting setup which we don't currently handle via the API. But we've got some recently where it's not "web_accept" but instead "cart" and we're trying to understand why.

The docs say "cart" is:

Payment received for multiple items; source is Express Checkout or the PayPal Shopping Cart.

We don't use express checkout or the shopping cart anywhere.

Can someone shed some light on this please?

I have a client who is experiencing this issue as well.

He sees anywhere from single-digit, to sometime triple-digit transactions in the course of a day; there doesn't seem to be any rhyme or reason as to why this occurs.

I've had to modify his IPN listener to identify and error-out these transactions, and then I re-process them manually. It's maddening.

It looks like it's beena  month since PayPal ackowledged this as a "known issue" - where is the situation right now as far as a correction?

Hi @DarrylHadfield,

This issue was resolved on the 21st July 2017

Sorry, @MTS_Justin, but no it isn't.

My customer continues to receive IPN responses from PayPal as recently as just a minute ago, where 
txn_type=web_accept  - and, more problematically, Item_Name=Shopping Cart   .  

The ITEM_NAME value should be something else entirely - "xxxx Test Code".  There is only one location where the PayPal buy-it-now button transaction originates, so that it would come in as "web_accept" and "Shopping Cart" is a surprise to all parties concerned.
