You can consider deleting deprecated keys, if you are running over the source key limit. However, be sure that deleted keys are no longer necessary for your project, as you cannot restore them if needed, and all the associated data is also deleted.
To automate the deletion of deprecated keys, create a new Automation in the Tools section of your project. Choose the action “Delete deprecated source keys” and configure it to trigger on events like key uploads. You can set filters to specify which keys to delete, such as those with a certain prefix.
