Associate a PayPal account to a buyer

There are a few ways to associate a PayPal account with a buyer.

​

Associate by buyer_id

The easiest way to associate a buyer with a PayPal account is to pass along a buyer_id when creating a PayPal account.

This will find a buyer with that id and associate the PayPal account with it. If a buyer with that id could not be found it’s ignored.

​

Associate by buyer_external_identifier

Alternatively, a PayPal account can be associated with a buyer by using it’s external_identifier. If a buyer with that external_identifier could not be found it’s ignored.
