php paypal adaptive chained payment implementation without leaving my website

I am tying to use PayPal adaptive chained payment API.

But, my problem is that, i don't want to leave my website for payment.

I want a kind of do direct payment using adaptive chain payment method.

I found api which do this by taking users to PayPal site,

but could not find the one which i want..

Any help would be welcomed..

Can Someone help?

My payment scenario is like this::

users will pay to my website i.e me, then after 3 days my application will redirect this payment to two of my clients parallely..

user -> me $100.

after 3 days.

me->my client1 = $70.
me->my client2 = $30.

this all process should be maintained on MY SITE ONLY.

This is not possible because of PayPal's security concerns and fraud protection. Users have to be redirected to PayPal's site in order to complete their transaction.
