Authorize/Settle
Using this API allows you to simply send a json request with a token to just **reserve **(authorize) or **charge **(settle) an amount.
Reserve an amount
Charge cardholder
When you reserve an amount on a stored card, the monthly allowance of the cardholder is reduced by the authorised amount, no matter whether the transaction will be settled later or not. The authorised amount is reserved for the merchant and should be settled within the period agreed with the acquirer. The issuer returns an authorisation code which serves as the reference of the authorisation. Once a transaction has been successfully authorised it can be settled.
Important: the cardholder will not be charged without settlement. Authorisation and settlement can also be processed in one single step. Please continue here with deferred settlement API if you just authorized the transaction.
When you charge a stored card, the authorization and settlement will be processed in one single step. The settlement is often also referred to as “capture” or “clearing”. Once you sent a charge request, the authorized amount is reduced from the monthly allowance of the cardholder and will be automatically settled, which means that the cardholder will be actually charged.
Stored cards can be used multiple times for recurring transactions or One-Click payments.
