This flow diagram shows an example of submitting a request to start the Card Operations session followed by a request to perform one of the operations. You will have to design your own process of which card operations you would like to perform and in which order. The different Card Operations requests are very similar to each other and operate in a similar way - the difference is mostly in the request body which includes the data specific to that type of operation.
This diagram also lists several optional steps (such as the AuthToken validation) which are not required and are listed only as a suggestion.
