GST for website/affiliate income[Foreign Remmitance]

Hi Everyone,

I am an Affiliate marketer 100% of my income is from Foreign remittances,

I don't have a GST number but my gross receipt is > 30 lakhs this year and 20+ last year.

As far as I know, OIDAR (Export @ 0%) should apply to my business https://www.meteorio.com/gst-oidar/

Will I be penalized! Please suggest what should I do? 

I am also willing to hire someone to do this for me. If you are an expert on this please PM me.
