API language with google sheet

Sorry if my question is too easy for you, but i’m an old man and a very newbee in programming language.
Do you know if it is possible to replace argument by a cell or a group of cells of google sheet in the command below?
Example: replace the key or id by a cell value.

Hi Vizar,

Sorry but I can’t help you with Excel or Google Sheets. I’d recommend using their help docs and forums.

Thank you.
Have a good day.
