The document outlines the steps for processing a payment through Authorize.net. Authorize.net manages the routing of transaction data between the customer, merchant bank, payment processor, credit card network, and issuing bank. It passes secure transaction information to the processor, who submits it to the credit card network and issuing bank. The issuing bank then sends funds to the credit card network and merchant bank, who deposits the funds in the merchant's account within 2-4 business days, completing the settlement.
