I want to pass the item description from STORE to PayPal Express. At the moment in PayPal I see only the order number. All the other details are passed such as billing details, but not an item description.

I installed the CI Merchant GitHub Forkbut its still the same? I made sure I replaced the current file with: system/expressionengine/third_party/store/ci-merchant/libraries/merchant/merchant_paypal_base.php

Does anyone have any idea what I am doing wrong or if anyone knows if its possible to pass an item or product description from STORE to PAYPAL.

I'm using the latest version of both EE and Store.

Many thanks


  • I tried adding item-by-item order detail to Store's PayPal Express payments (including shipping, tax, etc, all broken-out). It required modifications to a couple of files to get working ... but in the end it still threw an error after payment, during the verification callback. Eventually gave up. Jun 12, 2013 at 20:26

you'll need to modify merchant_paypal_express.php if you want to include transaction details with the payment request.

On or around line 84 you'll see the _build_authorize_or_purchase method where the details are passed on to Paypal. You'll need to edit this to include the description with the OrderDescription.

  • Hi Ian, Many thanks for your reply. I gave it a go, but nothing worked out, just got errors. Do you have an example of the updated code? Jun 13, 2013 at 11:12
  • Hi Graham. What are the errors you're getting back from Paypal?

  • Thanks for getting back. The errors were my fault as I was not sure about what I needed to edit. However I am going to do a bit more research before I ask for help and if successful I will post the code back here. Jun 14, 2013 at 19:42
  • Hi Ian, I added this line: $request[$prefix.'DESC'] = $this->param('OrderDescription'); I do not get an error, but in PayPal the Description now has the value of '0'. Jun 17, 2013 at 13:33

I believe the latest store update does exactly this
