Get returned URL from wp_remote_post if response code is 302

Question

I'm sending a POST request to an API:

    $payload = array('body' => $payload);
    $payload['redirection'] = false;

    $response = wp_remote_post( $settings['webhooks'], $payload );

    do_action( 'elementor_pro/forms/webhooks/response', $response, $record );

    $redirect_to = wp_remote_retrieve_header( $reponse, 'Location' );

The API endpoint returns a 302 redirect to a different URL: www.you-got-redirected.com.

How can I access www.you-got-redirected.com as a variable in PHP? I'm aware of wp_remote_retrieve_body but that's for the contents, not the URL.

I don't want to change the behavior of the API, and the documentation for wp_remote_post() says nothing about how to access the contents of the response.

EDIT: tried this but it always returns empty string

$redirect_to = wp_remote_retrieve_header( $reponse, 'Location' );

Answer 1

You almost had it.

In the $payload you need to set the default redirection param to 0/false, $payload['redirection'] = false;

The location header is empty because it followed through. Then you will be able to get the redirection URL from the Location header. You can see the list of arguments used here
