We’ve integrated a new REST API and embedded web server directly into the pihole-FTL binary.

We’ve seen a few posts of people asking where to find the API key – likely because their third party apps (that have yet to be updated to work with Pi-hole V6) are expecting one. The new API is fully documented on our docs site, but the short version of this is that there is no longer a specific API key, rather the API uses a session-based authentication token, which you can read about on the docs site.
