Test webhooks with zero infrastructure. We give you a throwaway inbox URL — use it as your callback_url and watch deliveries land here live. Support
callback_url in POST /v1/create_video, /v1/create_content, or /v1/enhance_script (the playground card has a callback_url field).video.processing first, then video.completed/video.failed).Inbox is ephemeral (kept ~1h, lost on server restart) and holds your last 50 deliveries. The unguessable inbox id is the only access token — anyone with the URL can read it, so don't send real data here.
