However, if you wish to use a third party shopping cart with our service, you may do so. The 2Checkout service generally is compatible with the following third party shopping carts:

• Any cart listed in our Recommended Cart section.
• Any shopping cart compatible with the Authorize.net parameter set, provided that it allows you to change the gateway URL. Nearly all shopping carts today support the Authorize.net standard.
• Any shopping cart that advertises 2Checkout support on their Web site should work with our service.
• Miscellaneous shopping carts. If your shopping cart does not fit either of the above criteria, or if it is simply in question, there is a way to determine whether or not your cart supports our service. Simply check with the manufacturer of the shopping cart to confirm it’s compatibility. You can contact the maker personally, go to their Web site, or read any documentation that may have been provided with the cart, itself.

TECHNICAL SUPPORT

2Checkout cannot provide technical support for questions regarding third party shopping carts. Basically, we did not develop them, so, therefore, we do not have any working knowledge of their inner mechanisms. Questions about configuration and/or setup should be directed towards the maker of the cart. However, we can provide technical support for questions or information needed to set up the shopping cart to work with our service.

You may find additional help regarding third party shopping carts from other sellers of ours by going to our Community, located at: http://www.2checkout.com/public/

Multi-page Payment Routine:

https://www.2checkout.com/checkout/purchase

Supports tangible and intangible products/services.

Single Page Payment Routine:

https://www.2checkout.com/checkout/spurchase

Can be used to sell tangible and intangible products/services when using third party carts.

Required Parameters:
sid – Your 2Checkout account number.
total – The total amount to be billed, in decimal form, without a currency symbol. (8 characters, decimal, 2 characters: Example: 99999999.99)
cart_order_id – A unique order id from your program. (128 characters max)

Product Identification Parameters:
Sites using this parameter set must pass in parameters to identify what is being sold during the purchase. These parameters will also be beneficial as when used correctly the product information will be displayed to customers on the purchase pages and will be listed on the 2Checkout.com sale detail page.

id_type – Due to changes in with the Product Identification parameters this parameter should be passed in once during the purchase and will need to have its value set to 1.
c_prod – The ID of the product that is being purchased. The quantity of product being purchased can passed with this parameter by placing a comma after the ID and then the quantity in numeric format.
c_name – The value of this parameter should contain the name of the product to be created. (128 characters max)
c_description – The value of this parameter should contain a short description of the product to be sold. (255 characters max)
c_price – The price of your product. Please note that in order to prevent a discrepancy between the total parameter and the sum of the product identification c_price parameters which may confuse the customer, the product price will not be displayed on the purchase page. (8 characters, decimal, 2 characters: Example: 99999999.99)

You can use these identification parameters to pass in multiple products as well. To do so you will need to append a digit to each parameter. For example, c_prod_1, c_name_1, c_description_1, c_price_1 will describe the first product, then to describe the second product you would use a 2 so the parameters will read c_prod_2, c_name_2 and so on.

Additional Parameters:
demo – Y to enable demo mode. Do not pass for live sales. Can also be controlled within the account.
lang – Chinese – zh, Danish – da, Dutch – nl, French – fr, German – gr, Greek – el, Italian – it, Japanese – jp, Norwegian – no, Portuguese – pt, Slovenian – sl, Spanish – es_ib, Spanish – es_la, Swedish – sv, defaults to English if this is absent, but en may be used for English as well.
merchant_order_id – Specify your order number with this parameter. It will also be included in the confirmation emails to yourself and the customer. (50 characters max)
pay_method – CC for Credit Card, CK for check, PPI for PayPal. This will set the default selection on the payment method step during the checkout process.
skip_landing – If set to 1 it will skip the order review page of the purchase routine.
x_Receipt_Link_URL – Used to specify an approved URL on-the-fly, but is limited to the same domain that is used for your 2Checkout account, otherwise it will fail. This parameter will over-ride any URL set on the Site Management page. (no limit)
coupon – Specify a 2Checkout created coupon code. If applicable, the coupon will be automatically applied to the sale.

To pre populate the billing information page you may pass in:
card_holder_name – Card holder’s name (128 characters max)

The card holder’s name can also be populated using the first_name, middle_initial, and last_name parameters. IMPORTANT: If you use these three parameters, the data will be combined into and returned as card_holder_name to your Approved URL script.

The billing information page will also be populated with the information from the shipping page if the shipping information is collected on that sale and the billing information is not passed in.

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.

You can receive back all of the parameters that were passed in as well as the following parameters:
order_number – 2Checkout.com order number
cart_order_id – Your cart ID number passed in.
credit_card_processed – Y if successful (Approved).
key – the MD5 hash used to verify that the sale came from one of our servers

Consult the documentation that came with your cart or contact the cart manufacturer for assistance with setting this up or to determine what URL you should enter on the Site Management for your cart to receive the product information.

Recurring billing can not be done with this parameter set. You must use the Plug-N-Play parameter set and have the products defined within the 2CO database for recurring billing.

Important: You can not mix the three parameter sets. This will cause problems during payment or may prevent the payment pages from working at all.

Please note that since this parameter set is for third party shopping carts, we do not collect shipping information for these types of orders. This is because your cart is responsible for calculating the shipping and it is passed in as part of the x_amount parameter.

It is also important to note that when using the Authorize.Net set of parameters, 2CO only requires the three listed under the required section. We will therefore not passback strictly Authorize.Net style parameters for everything unless they are passed in to us. This is not often a problem as most carts do this anyways. For example, x_First_Name and x_Last_Name will prepopulate the billing name, but 2CO uses card_holder_name for this. card_holder_name will then be returned unless x_First_Name and x_Last_Name are passed into 2Checkout.

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.

Return Parameters:
You can receive back all of the parameters that were passed in as well as the following parameters:
x_2checked – Y if card was successfully processed.
x_MD5_Hash – The MD5 hash that can be used to verify that the sale came from a 2CO server.
x_trans_id – the 2CO order number for the order.

Using this parameter set, we are not receiving any product information. As you can see, you are only passing in a total amount to us. Usually, the cart will have some means of using the x_invoice_num to determine what was purchased after the sale. A return URL will need to be set up on the Site Management page for the cart to correctly determine this.

Consult the documentation that came with your cart or contact the cart manufacturer for assistance with setting this up or to determine what URL you should enter on the Site Management page for your cart to receive the product information.

Recurring billing can not be done with this parameter set. You must use the Plug-N-Play parameter set and have the products defined within the 2CO database for recurring billing.

Important: You can not mix the three parameter sets. This will cause problems during payment or may prevent the payment pages from working at all.
