2Checkout Documentation

Pass Through Products

These parameters can be used to dynamically pass in tangible/intangible and recurring/non-recurring products, product options, shipping, taxes and coupons as items without having to create the products in the admin area.

Checkout URL

When testing in our sandbox, you will need to use our sandbox checkout URL:

Required Parameters

sidYour 2Checkout account number.
modeDefines the parameter set. Should always be passed as ‘2CO’.
li_#_typeThe type of line item that is being passed in. (Always Lower Case, ‘product’, ‘shipping’, ‘tax’ or ‘coupon’, defaults to ‘product’)
li_#_nameName of the item passed in with the corresponding li_#_type. (128 characters max, cannot use ‘<' or '>’, defaults to capitalized version of ‘type’.)
li_#_quantityQuantity of the item passed in with the corresponding li_#_type. (0-999, defaults to 1 if not passed in.)
li_#_pricePrice of the line item. Format: 0.00-99999999.99, defaults to 0 if a value isn’t passed in, no negatives (use positive values for coupons), leading 0 & decimal are optional. Important note: If the li_#_price parameter isn’t used to pass in line item pricing, the pricing for the corresponding item will default to 0.00.
li_#_tangibleSpecifies if the corresponding li_#_type is a tangible or intangible. ( Must be Upper Case, ‘Y’ or ‘N’, if li_#_type is ‘shipping’ forced to ‘Y’.)

You can use these parameters to pass in multiple products as well. To do so you will need to append a digit to each parameter. For example, li_0_type, li_0_quantity, li_0_name, li_0_price, li_0_product_id, li_0_description, li_0_tangible will describe the first product, then to describe the second product you would increment so the parameters will read li_1_type, li_1_quantity, and so on. Please Note: With this parameter set # may be represented by 0-999 and aren’t required to be consecutive.

Custom Parameters

You may pass in any additional parameters that you may need and they will be returned to you at the end of the sale. The only restrictions on custom parameters are that they can not share the name of ANY parameter that our system uses, even from the other sets. Please note that you WILL need a return script set up on the Site Management page to receive any of these parameters back as they are not included in the confirmation emails.

Parameters Returned

You will receive back all of the parameters that were passed in as well as the following parameters:

ParameterDescription order number
credit_card_processedY if successful (Approved).
totalthe total amount of the purchase
keythe MD5 hash used to verify that the sale came from one of our servers

Important: You can not mix parameter sets. This will cause problems during payment or may prevent the payment pages from working at all. Please Note: If you pass in a tangible lineitem and a shipping lineitem, the sale will automatically settle with-in 48 hours of being placed. If you pass in a tangible lineitem but no shipping lineitem, the buyer will need to select an existing shipping method that you created in your account and the sale will need to be marked as shipped before it will deposit into your pending payment. If the order is not marked as shipped with-in 7 days of being placed, it will need to be reauthorized prior to being marked as shipped. For more information on marking sales as shipped in the admin, please visit the Mark as Shipped section of our documentation. This can also be done using our reauth and mark shipped API calls which are outlined in the API documentation.
