Is posible to do a pre-authorization amount and then charge the real amount.

[Lkoy]

Hello, my question is about the mobile sdk. We are using the VisaPurchaseInfo and in the init we need a VisaCurrencyAmount with an amount, if we are doing a payment, like in a gas station to put fuel, but we don't know the final amount. There are any posibility to do a pre-authorization with an amount and when the transaction finished charge the real amount of money? Like in apple pay, they do a pre-autorization and block a quantity of money in your account and then charge only the amount that you really spend.

Hi, 

I see what you are seeking for. But before i can guide to the right API, can you please provide me some information on which product (mobile SDK) are you using? Also, please let us know if you have a relationship with Visa or not and are you an acquirer, issuer, or processor? 

Please let me know if you have any questions. 

Thanks,
