### Problem to solve Given I want to check if I have already forked a GitLab project, as of today, I have to search project by name in my namespace, which is fine for now, but could lead to collisions depending on the project name. ### Further details Being able to find my existing fork giving the project ID I want to fork will secure the result as working with ID avoid any kind of collisions. ### Proposal ### What does success look like, and how can we measure that? Success here looks like a new API method which receives a project ID, for which we want to get a fork or a `nil`. This should also be a performance improvement compared to search by name and namespace. ### Links / references
