WordPress Admin Ajax requests can be terminated programmatically using the wp_die() function. This function will stop the script execution and return an error message to the browser.

To use wp_die() to terminate an Ajax request, you can add the following code to your Ajax callback function:

function my_ajax_callback() {
   // Perform some tasks here

   // Terminate the request
   wp_die();
}

You can also pass an error message to the wp_die() function to provide more information to the user:

function my_ajax_callback() {
   // Perform some tasks here

   // Terminate the request with an error message
   wp_die( 'An error occurred while processing the request.', 'Error', array( 'response' => 500 ) );
}
