Starting the card-linking flow

On any action that you want (on a tap of a button, for example), add the following code:

12
Fidel.start(from: yourViewController)

The Fidel.start method replaces the previous: Fidel.present method. To get notified about card enrollment events, you ca use the Fidel.onResult callback. Please check our v2 Reference documentation for more details.
