How can I create a donate button that sends money to someone else using their paypal merchant ID?

[Essence_of_Pure]

In a website, I need a way to automatically generate donate buttons for each of its users. The user provides their paypal merchant ID in their account settings, then I can use that to create a payment. Which API endpoint can I use to accomplish this?

You will have to specify the merchant ID in the payee object in your web API request.
