Extract the files into the appropriate directories.

Go to http://<www.yourdomain.com>/<youraffiliatedir>/2checkoutinstall.php
to populate the databse. Ensure that you remove 2checkoutinstall.php once
you have run it once.

Then please follow these instructions:

When setting up the 2checkout.com parameters, you need to enter the following

recurring => Yes/No
sid => This is your 2checkout.com login id
product_id => This is the product id that you have set up in 2checkout

For existing products, make sure you edit each item to make sure they have the appropriate settings.

Although you can set certain items as recurring and non-recurring, DH-MLM can only be set up to credit customers either once-off or repeatedly.

-------------------------------

Once this process is complete, there are 2 ways to send the customer to 2checkout.com

One way is to use a form. You need to enter the following as a hidden field to be submitted to 2checkout:
<input type="hidden" name="merchant_order_id" value="[Enter DH-MLM item id here]">


The other way is to use a direct link (eg. through emails).

You must redirect your customers to this file instead of the one provided by 2checkout.

start2checkout.php?itemid=[Enter DH-MLM item id here]

This file will automatically direct the customer to the 2checkout payment page.


After the customer makes a payment all passback parameters from 2checkout will be emailed to the email address that you have setup in DH-MLM. The receipt numbers in DH-MLM will coincide with 2checkout so refunds/chargebacks can be easily handled (note that the R from the recurring products receipt number is removed, ie. R123456 is saved as 123456 in DH-MLM).

Explanations of each passback parameter can be found at 2checkout.com

Inside 2checkout.com, please make sure that you set the final completion URL page to the one you see under Affiliate Settings in the admin control panel. It should be of the form: http://yourdomain.com/affiliatedir/2checkoutcomplete.php
