# custom callback function

 * Hi, just found this plugin and just what i need – however i need a way to trigger
   a custom function (callback) on success of a transaction ( $ipn_verified = true).
   I used to write this stuff manually years ago and cant remember if this is the
   same as status=”success” denoting a successful transaction. Other statuses would
   have been (or probably still are) ‘pending’, ‘on-hold’, ‘failed’ etc.
 * Do i use the, $ipn_verified = true var to denote a successful transaction? and
   if so how do i hook into the script (paypal_IPN.php -> wp_paypal_process_ipn())
   to call my callback function.
 * Thanks

 * [@trutherone](https://wordpress.org/support/users/trutherone/), You can use the“
   wp_paypal_ipn_processed” action hook that gets triggered after a PayPal notification
   is processed in the plugin. Example:
 *     ```
       function wp_paypal_ipn_callback( $ipn_response ) {
           /* Your code */
       }
       add_action( 'wp_paypal_ipn_processed', 'wp_paypal_ipn_callback', 10, 1 );
       ```
