Associate a transaction to a buyer

Once a buyer has been created it’s possible to link transactions to that buyer. There are a few ways to associate a transaction to a buyer.

​

Associate the payment method to a buyer_id

The easiest way to associate a buyer to a transaction is to pass along a buyer_id when creating a transaction.

This will find a buyer with that id and associate it to the payment method for this transaction. If a buyer with that id could not be found it’s ignored.

​

Associate by buyer_external_identifier

Alternatively, a transaction can be associated to a buyer by its external_identifier. If a buyer with that external_identifier could not be found it’s ignored.
