Hi, I am attempting to make my first online e commerce shop, so I have a a lot to learn. I have a supplier, who has an API-key for me to use, but I can't find where to insert this API-key, do I need an extension for using it? I have tried to google a lot about it, but I can't find any useful information about it.
I don't know much about API, exept for it exchange datas between supplier and the online shop, so I would like to know if an API-key can insert pictures and information on a website like a CSV-file?
I would appreciate any information about it, and how to insert this API-key.
