Your users need to Grant API Permissions for your application to make API calls on their behalf. Then you would still use your own API username, password, and signature, but you'd also include a SUBJECT parameter along with those. The SUBJECT value would be the email address or PayPal merchant ID of a user who has granted permissions for your app.

Users can grant permissions manually through their PayPal profile, or you can build this into your app using the Permissions API. If you go with the permissions API, though, you end up using tokens in the header (OAuth) as opposed to the SUBJECT parameter.

The payment wound up in the sandbo_1204199080_biz@angelleye.com account. Just make sure you have the same value set in both SetExpressCheckout and DoExpressCheckoutPayment and you should be fine.
