Managing disputes via the API is only available to merchants who can access disputes in the Braintree Control Panel.

If you want to look up a single dispute using its ID, use the find method.

PHP
$dispute = $gateway->dispute()->find("a_dispute_id");

If the dispute can't be found, you'll receive a Braintree\Exception\NotFound exception.

Arguments
disputeId required, string

The unique dispute identifier.
