In the present flow of Span payments, the Span application transmits billing information and credit card data to the Span Payment API server. These details are sent to Cybersource Simple order API by the span Payment API server.

The cybersource simple order API sends responses to the Span Payment API server. Finally, the payment API server sends the response to the Span Application.

New Credit Card Payment Flow

The ETT application Flex Microform and TMS do the following process.

The Flex microform generates the public key based on the RsaOaep256 algorithm and domain name.

The Flex microform generates the JWT token based on the Credit card information.

Finally, the ETT application creates a Payment request to the Cybersource REST API using the JWT token and billing information. The Cybersource REST API sends responses to the Application.

If Users Add the First Credit Card information for the ETT Application in the Account Create a Customer ID Token Payment Instrument ID, instrument identifier ID, Request ID, and the customer ID Token Stored Against Users else

Users already added credit card information Then adding a new credit card only creates Payment Instrument ID, instrument Identifier ID, and Request ID The customer ID was not created newly linked with the existing Customer ID Token
