Why the Backend Development and API's certification does not have any content?

i have almost completed my frontend course, now i want to backend but there isn’t any content under the Backend Development and API’s certification, does anyone know why ?

if it isn’t gonna come anytime soon, can anyone suggest from where i should learn backend ?

It’s not there because it isn’t ready yet. Looks like it’s estimated to be available in late 2026.

While you’re waiting for that, there’s some older stuff in the archive. It’s no longer updated, but it worth a try.

The first back end section covers relational databases and I’ve just double-checked - the course is working.
