Wordpress Ninija form redirect - wordpress

Question

I tried to redirect to another form/page by condition.
I used Ninja Forms (3.3.) at Wordpress 4.9..
I created webhook.
following is code
add_action( 'generate_token', 'generate_token_callback' );
/**
* #param $form_data array
* #return void
*/
function generate_token_callback( $form_data ){
global $ninja_forms_processing;
$form_id = $form_data[ 'form_id' ];
$form_fields = $form_data[ 'fields' ];
foreach( $form_fields as $field ){
$field_id = $field[ 'id' ];
$field_key = $field[ 'key' ];
$field_value = $field[ 'value' ];
// Example Field Key comparison
if( 'my_field' == $field[ 'key' ] ){
// This is the field that you are looking for.
}
}
error_log( "get token - " . $form_id, 0 );
$form_settings = $form_data[ 'settings' ];
$form_title = $form_data[ 'settings' ][ 'title' ];
error_log( "get token 2 - " . $form_id, 0 );
if($form_id == 2) {
$url = get_home_url() . "/thankyou" ;
wp_redirect( $url );
}else{
$url = get_home_url() . "/error" ;
wp_redirect( $url );
}
}
The wp_redirect is not working. How can I?

You only miss the exit(). So just add it after wp_redirect. whenever use wp_redirect use exit() method.
if($form_id == 2) {
$url = get_home_url() . "/thankyou" ;
wp_redirect( $url );
exit(); // always exit
}else{
$url = get_home_url() . "/error" ;
wp_redirect( $url );
exit(); // always exit
}
