you need hosting (localhost for start is okay) for create REST API script and some programming skills. "chromiumupdateurl" is url to your script. (important notice: all percent-formating operand (%d, %s) ang GET arguments need to be ordered as in chrlauncher.ini example). returned data is single string as "key:val" with semicolon delimeter. for example you can open "chromiumupdateurl" with replaced percents as %d to 32 or 64 and %s to <any of build type> (all values in chrlauncher.ini). i cannot post any better example for some time, but all is simple.
