Post info to Webflow site using PHP cURL script and Zapier

My client has a restaurant site built in webflow where we need to keep an up-to-date lunch menu using info fetched from an external site using api. Using Zapier webhooks is an option.

This is the script $client = curl_init('http://api.xxxxxxx/api.php?token=xxxxxxxxxr&type=lunchlists&week=next_week');

curl_setopt($client, CURLOPT_RETURNTRANSFER, true);

$response = json_decode(curl_exec($client), true);
