For my use-case, I need to confirm if a user has processed a transaction at a certain merchant between a certain time for a certain amount. Thus I need to query for transactions with the following details: timestamp(i.e 3:03 pm GMT on 12-01-2018) and value(i.e $3.65) of authorization for a user at a specific merchant (I.e Starbucks). Does this feature exist in the visa API and in which API ? and is the usage charged per requests based(# of API requests) or per user based(# of users) for production?
