You can cause TFLogin to send an email confirmation message and evaluate a block that you provide when the user navigates to the confirmation URL. This feature uses the same mechanism as is used for registration confirmation, username reminders, password resets, and account change confirmations.

The TLPendingUserAction is a subclass of TLUser and is a copy of the user for which the action is being confirmed. The confirm block that you provide is passed the TLPendingUser object. Note that when it is evaluated, the session context will be different than when the pending action was queued.

Here is an example from TLTestApp. Other referenced methods can be seen in the TLTestApp source code.

confirmWithUser
    | url userAction |
        "Instantiate a TLPendingUserAction object for your
        user and provide a one-argument block to be evaluated
        when the user confirms."
        userAction := TLPendingUserAction 
            forUser: self session user
            onConfirmDo: [ :confirmedAction |
                "In our action we will log the user in and set
                 a flag indicating that they have confirmed."
                loginComponent loginUserById: confirmedAction userId.
                self testConfirmed: true ].
	
        "Queue the pending user action. It will remain active
        for the configured confirmation timeout period. This
        method answers the confirmation URL to which the user
        must navigate to confirm the action." 
        url := loginComponent addPendingUserAction: userAction.
	
        "Send a confirmation email to the user."
        self
            sendTestConfirmationUrl: url
            to: self session user email
            timeout: (self application
                preferenceAt: #confirmationTimeoutMinutes)
