# Which Problems Are Solved
This PR *partially* addresses #9450 . Specifically, it implements the
resource based API for app keys.
This PR, together with https://github.com/zitadel/zitadel/pull/10077
completes #9450 .
# How the Problems Are Solved
- Implementation of the following endpoints: `CreateApplicationKey`,
`DeleteApplicationKey`, `GetApplicationKey`, `ListApplicationKeys`
- `ListApplicationKeys` can filter by project, app or organization ID.
Sorting is also possible according to some criteria.
- All endpoints use permissions V2
