Code Snippet #3

For sending mail for referral

The provided Power Fx code snippet is used within a Power Apps application to interact with a Power Automate flow named ‘Send-a-email-to-friend-with-referral-code’. The code sends an email to a specified address and handles the response to indicate success or failure of the operation.

   If(
        'Send-a-email-to-friend-with-referral-code'.Run(
            txtFriendEmail.Text,
            "Referral Instructions",
            lblReferralCode.Text,
            User().FullName
        ),
        Notify(
            "Email sent to " & txtFriendEmail.Text,
            NotificationType.Success
        );
        Reset(txtFriendEmail);
        ,
        Notify(
            "Error, We are not able to send mail!",
            NotificationType.Error
        )
    );

Explanation

• Calling the Power Automate Flow named 'Send-a-email-to-friend-with-referral-code'.Run(txtFriendEmail.Text, "Referral Instructions", lblReferralCode.Text, User().FullName): - This part calls the Power Automate flow 'Send-a-email-to-friend-with-referral-code'. The .Run(...) function executes the flow with the following parameters: - txtFriendEmail.Text: The email address entered into a text input control (presumably where the user inputs the friend’s email). - "Referral Instructions": A string literal, likely the subject or a part of the email content. - lblReferralCode.Text: The text of a label control, possibly containing a referral code to be sent in the email. - User().FullName: The full name of the current user, retrieved from the user’s profile in Power Apps.

• Handling the Response from the Flow: This If(..., ..., ...); If statement that checks the result of the flow execution. If the flow runs successfully, the first block of code inside the If statement is executed: - Notify("Email sent to " & txtFriendEmail.Text, NotificationType.Success);: Displays a success notification message to the user, confirming that the email has been sent. - Reset(txtFriendEmail);: Resets the text input control where the friend’s email was entered, likely to clear it for future input.

  • If the flow does not run successfully, the second block is executed:
    • Notify("Error, We are not able to send mail!", NotificationType.Error): Displays an error notification message to the user, indicating that the email could not be sent.

In summary, this Power Fx code snippet is designed to integrate a Power Apps application with a Power Automate flow. The flow is responsible for sending an email with referral instructions and a referral code. The Power Apps application calls this flow, passes necessary parameters, and then provides feedback to the user based on whether the email sending operation was successful or not.
