ConvertPlus URL parameters


Use 2Checkout ConvertPlus to provide your customers with a swift and safe payment experience. Depending on your desired workflow, you can either create ordering interface links using our dedicated interface (ConvertPlus) or generate the parameters dynamically, in your own system.

2Checkout enables you to use ConvertPlus with both catalog products, and with products generated dynamically via buy link parameters.


Eligible 2Checkout accounts. Contact 2Checkout to inquire about ConvertPlus. 


To use ConvertPlus dynamic ordering, pass the dynamic parameter with TRUE or 1 value. When creating orders with catalog products, the prod parameter should contain the product code of your catalog item. For dynamic ordering, the prod parameter should contain the name of your dynamic product.  

How to create dynamic ConvertPlus buy links

  1. Start from the base ConvertPlus buy link:
  2. Add your merchant code to the buy link, so that 2Checkout links the sale to your account. Your merchant code can be found in your Control Panel, in the Account Information area. Example: merchant=2COLRNC.

  3. Set the dynamic parameter to TRUE or 1.

  4. Add product information such as product typename, price and quantity.

  5. Include additional product information, such as recurring options or customer redirect URL.

Buy link parameters

 When you generate a checkout link, 2Checkout automatically includes some of the parameters in the list below in the URL, depending on a number of variables, such as the products, discounts, currency, and more. You can use these query parameters to generate checkout links in your own system, without having to rely on the functionality in you account.

In the Control Panel, click to edit a product, and select the Information tab. The Product code of the item you're editing is available at the top of the General area under Information.

Warning: Changing a product code already used in active buy links will completely break the checkout flow for those links. If you change a product code, make sure all your buy links for that product are replaced with new links generated with your current product code.

prod For dynamic products

Set the dynamic parameter TRUE to use dynamic products in the ordering process.

When using dynamic products, the prod parameter contains as value the name of the dynamic product. For multiple products, send them separated by a semicolon.

Example: name1;name2;name3.
