When a merchant initiates an authorization request, they send transaction details such as the amount and the card information to the payment processor, which in turn contacts the card issuer for approval. This mechanism is essential in preventing fraud and ensuring that only legitimate transactions are processed, protecting all parties involved in the transaction. The successful authorization guarantees that the merchant will receive payment, while also allowing the cardholder to manage their credit effectively.
