Transloadit will contact the specified notify_url when an Assembly is finished; if your development environment is behind a firewall, use Cloudflare Tunnel, ngrok, or the first-party @transloadit/notify-url-relay via npx -y @transloadit/notify-url-relay (the relay differs from tunnels by polling public status and forwarding terminal notifications to your local notifyUrl).

If your workspace has multiple developers, each of them will need to supply a different notify_url. To overwrite the notify_url specified in your Template, use a hidden input field named params in your form to pass a new value.

For more details, see our documentation on Dynamic Assembly Instructions.
