Paypal API Support for Trading platform usecase

Question

Use-case

1. A Trading-platform for selling goods where each subscriber can purchase and sell ( eg. eBay )
2. Trading-platform takes commission for each transaction

Flow of actions

1. Buyer execute a purchase
2. Funds are transferred from the buyer account to the Trading-platform account
3. PayPal takes it's transaction commission
4. Trading-platform takes it's commission
5. Trading-platform transfer the reminding funds from it's account to the Seller account
6. PayPal takes it's transaction commission

Problem at hand

1. As can be seen in the above 'Flow of actions' PayPal will charge for commission twice
   
2. this composite transaction model considerably complicates implementation/cost.

Feedback required

• Is there any payment model with which this can be avoided?
• Is there any payment model where for each transaction a subset of the total sum is sent to the trading platform account ?

Any help will be appreciated

Answer 1

You could use Adaptive Payments for this. With Adaptive Payments, you can split payments up and set who pays what fees.
