Getting Data from external API chrome extension

Hi,
I built a website on the bubble platform, and now I’ve partnered with a developer that would like to develop a dedicated chrome extension that will save data into my website database.
This chrome extension will be developed outside the bubble platform as a python code.
The main idea of the extension is when user scroll on social media platforms like IG, X, FB, or Tiktok, they will be able to right click on a given post, and automatically direct this post details onto my website database.
The data that will be entered is a post link, post description ( entered manually by the user), and possibly a user name.
I would appreciate if you can help with general instructions on using the API connector for that use case, and setting up my side to be ready to receive the data from external API.

Thanks

why don’t you build the full thing in Bubble using buildwithcharles.io i crated to build chrome extensions from bubble apps?
