Hi. I have a standard form that is configured to create an entry in another form via API. I am trying to find a way to redirect a user to a view for the second form (parent) based on the JSON entry_key value provided in the API response from the first API call. I have tried accomplishing this using the below php code to no avail.

add_action( 'frmapi_post_response', 'frm_save_api_response', 10, 3 );
function frm_save_api_response( $response, $entry, $form_action ) {
$body = json_decode($response['body'], true);
$returned_key = $body['item_key'];
if ( $body['form_id'] == 2) {
header("Location: https://website.com/?entry_key=$returned_key");
) );
}
}

  Below is the body of the API response I receive from the first API call. In this case, I want to use the response to redirect a user to the view at https://website.com/?entry_key=4szaj  

"body": "
{
"id": "198", "item_key": "4szaj", "name": "test 1234", "meta":
{
"ol4jm":
{
"form": "3", "i197":
