How can I track origin of a sale?

I work with bloggers who write reviews about my app. I would like to track sales that originate on specific sites so I can pay them commissions, like an affiliate program.

For example, if a person discovers our app by reading a review, I would like to give the blogger a URL to the App Store a UTM code so that I can track if the article generates sales of my app.

if there is a 3rd party affiliate program management platform or software to do this, I might be open to using it.

i’ve tried searching the web and other developers about this. It should be simple but it’s elusive if it’s out there at all.
