how do i make an invented opening official?



Openings become official due to widespread recognition usually from top games/ players. Your best bet is to convince a recognizable player to use it in some important blitz games. Of course the line would have to actually be that good to warrant it.

Just defeat Magnus Carlsen with it.
He left out "multiple times and with a plus record"

Once or twice is enough.
This is how Reti made his opening official.

OK so I exagerrated in its utility but it’s teeming with traps, so you need to do THE right moves to avoid them. Here it is; 1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 d5 6.Bb3 I include 2 traps, here: 6...dxe4?? 7.Bxf7+ and white is winning. The second one: 6...Nf6 7.e5 Ne4 8.f3 Ng5 9.f4 Ne6 10.f5 Ng5 11.h4 and the knight is trapped. Oh yeah I’l try to be GM and beat other GMs with it (btw I thought of a name for it already). Thanks for the advice!
You can't make an opening "official." There is no international licensing body. If there was, the Ruy Lopez family would own all of Spain
