Feel free to open a dedicated thread regarding your issues. Have you tried the Redirect app in proxy mode? (though it’s quite simple and would require further manual NGINX tweaks to make some apps work)
Good news, we include the Lexicon library, to directly interface with your registrar API (if compatible, obviously) if you supply it with proper credentials.
Any contribution is welcome in the documentation, we have a tutorials section in there, and in the forum too. Core and apps contributors are a tad too focused on making the standard features work to delve into more complex issues right now.
What the fuck. Why would anyone do that. (rhetorical question, no need to answer further).
