After a consenting user makes a purchase, what is the smallest possible time for that transactional data, eg a $6 coffee to land in the hands of a company for it to then trigger an event? Please let me know if anyone could give any insight into this or if you could refer me to a person that could help.

THIS IS NOT MICRO INVESTING
