startPaymentFlow

Starts the payment flow for the vaulted payment method. You can get the id from any instance of PrimerHeadlessUniversalCheckout.VaultedPaymentMethod returned by fetchVaultedPaymentMethods.

Additionally you may pass vaultedPaymentMethodAdditionalData, which might be required by some payment methods (e.g. you might need to pass CVV which can be recommended to increase auth rates).

Make sure that vaultedPaymentMethodAdditionalData is validated before being passed to this method.

Upon a successful invocation of this function, the SDK will automatically trigger the standard payment delegate methods.

func startPaymentFlow(vaultedPaymentMethodId: String, vaultedPaymentMethodAdditionalData: PrimerVaultedPaymentMethodAdditionalData? = nil)
