API Keys
Where to find API keys
You can get your in the detail of your project under the API keys button

Permissions
Each API key is tied to a project and has permissions which can be adjusted at any time. Latta also supports restricting keys to certain origins and IPs.
Refresh and deleted
If you no longer need a key it is best to delete it.
In the unfortunate case of your key leaking you should immediately refresh it, this is going to discard the old key and create a new one with the same exact settings.
