I update my source code for the collaboratory google tool. This colab notebook comes with source code for an update of IPython, PyTikTokAPI python module using the cookies browser, and a simple OpenCV test to create an image and show with google.colab.patches.
The cookies for the TikTok package module can be found in any browser by pressing the F12 key.
I don't find a good python package that parse the tiktok content.
The application for development with TikTok looks like Instagram and Facebook ... you can test it at https://developers.tiktok.com/app/.
