Gateway Setup
More info @ www.2checkout.com

For details on how to set up 2Checkout INS (Instant Notification System), click here.
Account Number
Your 2Checkout account number.
Secret Word
Specify your 2Checkout secret word. This is set in your 2Checkout account area.
Information About this Payment Method
This is presented to visitors if they click for more info on the gateway on the checkout page. Optional.

Use BB Code for formatting, HTML is not allowed.
Order Status Preferences
Specify which order statuses to set for callback operations. Leave as default if you aren`t sure. "Pending" statuses restrict download access for none gateway methods and should be used until payment is cleared.

Setting preferred order statuses can be useful for filtering with other admin operations.
Alternative Redirect Url (Optional)
Alternative redirect url is the page a visitor will be directed to after a successful transaction.

You should NOT use this option if you sell downloadable items as visitors will not be able to download their products immediately after purchase.

Enter full url starting http://

If you need to do further operations on your redirect page based on the sale, the following query string params may be used and passed to your new page:

{id} = Sale ID in Database
{code} = Sale Buy Code in Database.

Example:

http://www.example.com/new-redirect.php?id={id}&code={code}
IMPORTANT! When using these variables on your custom PHP page, make sure you check and sanitize the variables accordingly. The {id} value will always be an INTEGER and the {code} variable ALPHANUMERIC.
Live Payment URL
Live payment url. At the time of these docs it is:

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

This should not be changed unless altered by the gateway.
Test/Sandbox Payment URL
Sandbox or test payment url. In many cases, this is the same as the live payment url. At the time of these docs it is:

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

This should not be changed unless altered by the gateway
Language
Supported 2Checkout languages. Check the 2Checkout site for further updates.

If more languages are supported, add them to the $twoCheckoutLanguages array in the 'admin/control/arrays.php' file.
Payment Method Availability
Choose when this payment method is available. Useful if you only want certain methods shown for certain checkout types. If none are selected, defaults to all.
Enable 2Checkout
Enable / disable this gateway as a payment option.
Note
In test mode 2Checkout does NOT send any INS post data back to the website, so its very difficult to test 2Checkout successfully in test mode. A live payment will probably be your best way of testing. An option to utilise the 2Checkout INS simulator may be built in at a later date.
