Hello I need to unlock my app how can I do it?
Welcome to the Atlassian Community!
The short answer is that you need to log in as the user of your app, this will reset the "overuse" flag.
The longer answer is that you will need to do that, and then rewrite your app such that is not making thousands of requests of Trello every hour.
