My boss, who operates in the grey industry (not in Europe or the US), runs an online entertainment platform that includes sports betting, etc.

I’ve been searching online and found some information that I hope will help me modify the betting content. For example, I want to change a “buy big” bet to a “buy small” bet.

The data I’ve collected suggests that SQLi and BOLA are the directions I should research.

I would greatly appreciate any valuable advice from everyone. Which direction should I take to accomplish this task?

I also hope to find someone who can collaborate with me on this project.

Very sorry, my native language is not English. Thank you for your valuable time.
