Mixamo.js

// Mixamo Animation downloadeer
// The following script make use of mixamo2 API to download all anims for a single character that you choose.
// The animations are saved with descriptive long names instead of the short ones used by default by mixamo UI.
//
//  This script has been written by [email protected] and the author is not responsible of its usage
//
//  How to use this script
//  1. Browse mixamo.com
//  2. Log in
//  3. Open JS console (F12 on chrome)
//  4. Download an animation and get the character ID from the Network tab
//  5. Then past the character id in the "character" variable at beginning of this script
//  6. Copy and paste the full script in the mixamo.com javascript console
//  7. The script will open a new blank page.. you  will start to see animations downloading
//  8. keep the blank page opened and keep on pressing "Allow multiple downlaods" 

// NOTE. This doesn't really work for me, but it was supposed too
// Chrome will ask you all the time to allow multiple downloads
// You can disable this as follow:
// chrome://settings/ > Advanced > Content > Automatic downloads > uncheck "Do not allow any site to download multiple file automatically"

// CHANGE THIS VAR TO DOWNLOAD ANIMATIONS FOR A DIFFERENT CHARACTER
// const character = 'aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'
const character = '2b3be6e3-a811-4a3d-a44e-fa2fa827bc93'

I get some errors when i add: gmsHashArray[0].inplace = true;

before - body: JSON.stringify(exportBody)
VM448:154 Uncaught SyntaxError: Unexpected token '['

after - body: JSON.stringify(exportBody)
VM451:155 Uncaught SyntaxError: Unexpected identifier

is there a way to also download appropriate gif with each animation? image id is in gms_hash, but I can't figure out the cors, cloudfront is refusing.
