eCommerce transactions are handled as "card not present" transactions. This includes In-Application and online payments.  These process as credit transactions.

On eCommerce cardholder-initiated transactions (CIT), merchants processing on the GSAP-NA host may request that the issuer extend the authorization validity up to 30 days; this is applicable to Visa cards only.  This is handled by setting the ExtendedAuthInd in the transaction request to true.

Please note that the transaction approval response code is independent of the approval for the extended timeframe.  The ExtendedAuthRsp element in the response indicates whether the extension was granted by the issuer.
