https://github.com/B16f00t/whapa https://github.com/B16f00t/whapa (among other tools) appears to download it from Google without requiring any key from facebook or a rooted device. I haven't tried this specific tool yet (or others recently) but it was definitely possible in the past without requiring any key from FB/WA.
