A very simple marketplace is almost not possible today.

[Rantrg]

We would like to let person A pay person B some amount of money without taking any fee using PayPal in our platform.

It seems that Paypal closed EVERY kind of product that allowed you to do so in the past (such as Reference Transaction, Adaptive Pay, Marketplace APIs)

But things look very weird, still.

Option 1:

PayPal has this link that allow you to send payment on behalf of a person to another email (which they seems to almost hide in their docs):

https://www.paypal.com/cgi-bin/webscr?&cmd=_xclick&business=emailAddress&currency_code=EUR&amount=0.01&item_name=Test description

Here we can set the email of the receiver. The problem is that in our platform, once the link was clicked, we will never know if the payment has been made because there is no redirect or callback function . No option for a dynamic redirect with email address. No JS API.

option 2 :

Using the Paypal Commerce Platform I can use the API to let person A pay person B, the problem : both of them need to be onboarded to Paypal Commerce Platform . which makes it harder for the seller that must register as a business owner to do so before start selling.

Today if a seller want to sell in any marketplace (e.g Fivver/Etsy/Ebay) using Paypal, he only need his email address and a simple PayPal account.

That means option 2 is not what most marketplaces uses because you register only with a private PayPal account to sell, and do not have to register to any program. If they use option 1, how do they know that the buyer actually clicked Pay ?

Option 3

The new Smart Payment Button which allow only one email of the receiver - the one tie with the tokenID and no other.

Question :

In option 1 is there any way using Javascript/html to know after a user redirected to the link in option1, if he did actually finish paying to the other person or left (so my platform can save the data?

If not, how its being done on other websites such as Etsy that use probably option 1 ?

Is there any simple way to let someone get paid only by email in a platform with out any fee to the platform ? just letting it know the payment is done?

Thanks.
