Hey Everybody, I'm new here I'm sorry if im posting this question in the wrong section, but could not find any better forum.

I'll explain briefly my problem, I was asked to design  an ebay store for one of our client, but since the store is already selling I cannot make live changes nor i can interrupt sales.

I was wondering if i could somehow use the sandbox store to test my design and API calls, couldn't not find any documentation in that regard.

Thanks in advance.

Daniel
