Integrating an SDK / .php file?

Need help APIs
3

Thanks for the response @tanejachirag19. Appreciate you trying to help.
However, I’m not sure how this would actually work. Mainly because it’s not clear how I would be able to download the NitroPack SDK and “upload it to your site in a directory of your preference” (per the guidelines in the image I included).
Also, I read this post on the Bubble Forum post from @constantingaspar: “What you can do is an API call to your PHP script located somewhere else.”
Do you, or anyone else know how I would be able to either upload an SDK to my webapp, or call and API whenever a user loads a page? (you can see the NitroPack API here)
Truly appreciate any guidance on this.
