We’re introducing App and App Feature slugs to make app identification clearer, and safer.
Instead of relying on numeric IDs, apps and features will now use human-readable, globally unique slugs that are easy to recognize and reference.
For new apps, slugs must follow a clear structure based on your account slug, and you can add slugs to existing apps in the General settings page.

Existing apps continue to work as-is, with full backward compatibility.
When updating features in the Developer Center, you’ll be prompted to set a feature slug.

Check the docs and get started in the Developer Center to explore how app and app feature slugs work.
