How do I add an Authorize.Net Simple Checkout item?

  • Go to the Authorize.Net merchant login page, and login.
  • In the merchant interface, in the left sidebar, in the "TOOLS" section, click the "Simple Checkout" link.
  • In the "Item Id" column, choose an unused value and make a note of it.
  • Click the "+ Add Item" link, which takes you to the "Simple Checkout Item" page.
  • Enter an "Item Name", which is limited to 31 characters.
  • Enter the "Item ID" you chose earlier.
  • Set the appropriate "Type".
  • Enter a detailed "Description" of the product or service.
  • Enter a price. No dollar sign is needed.
  • Change the "Maximum Per Order" if needed.
  • Click the "Save" button.
  • On the next page, in the "Buy Now Button Code" section, find the value to the right of the "LinkId". It will comprise 36 characters (letters, digits, and hyphens). Make a note of it, because you will need it later, when adding the item to your website.
