# Set the payment method to be used for this online transaction

Different payment methods incur different rates, so the payment
method to be used for a transaction must be set before the
payment is made. This requires retrieving the charge associated
with the payment method using
GET /transactions/{transaction_id}/charge, and passing the
generated charge as a parameter to this endpoint.
