API invalid

When I went to update to the latest version of Etsy plugin. I lost the link to my esty shop on my website. When I try to regenerate a new Etsy APP it provides me a string of numbers and symbols but still reads invalid. How can I validate my API. Is there a waiting period?

Please help.
