Notify Function for Messages in Power Apps – Complete Guide

📌 Introduction

The Notify() function in Power Apps is a powerful tool for displaying messages to users. It is commonly used to provide instant feedback, error messages, success notifications, and warnings within an application. Notifications help users understand what is happening in the app and guide them on what to do next.

🔹 Step 1: Understanding the Notify() Function

✅ Syntax of Notify()

Notify( Message, NotificationType, Timeout )

Message → The text of the notification.
NotificationType → Defines the type of message (Information, Success, Warning, Error).
Timeout (Optional) → Specifies how long the notification appears (default is 10 seconds).

✅ Available Notification Types

Notification Type	Description	Example
`NotificationType.Information`	Displays an informational message	“Data loaded successfully!”
`NotificationType.Success`	Indicates a successful action	“Record saved successfully!”
`NotificationType.Warning`	Warns users about potential issues	“Please fill in all required fields!”
`NotificationType.Error`	Shows an error message	“Failed to connect to the database!”

🔹 Step 2: Basic Usage of Notify()

✅ Example 1: Displaying a Success Message

Notify("Record saved successfully!", NotificationType.Success)

📌 Displays a green success message for 10 seconds.

✅ Example 2: Displaying an Error Message

Notify("An error occurred while saving!", NotificationType.Error)

📌 Displays a red error message.

✅ Example 3: Displaying a Warning Message

Notify("You must enter all required fields!", NotificationType.Warning)

📌 Displays a yellow warning message.

✅ Example 4: Displaying an Information Message

Notify("Data is being processed, please wait...", NotificationType.Information)

📌 Displays a blue information message.

🔹 Step 3: Controlling Notification Duration

By default, a notification is shown for 10 seconds. You can change the duration using a timeout value (in milliseconds).

✅ Example: Setting Notification Duration to 5 Seconds

Notify("Short message!", NotificationType.Information, 5000)

📌 The message will disappear after 5 seconds.

✅ Example: Keeping the Notification Visible Until Dismissed

Notify("This message stays until you close it!", NotificationType.Warning, 0)

📌 Setting timeout to 0 keeps the message until the user dismisses it manually.

🔹 Step 4: Using Notify() with Buttons

✅ Example: Displaying a Notification on Button Click

1️⃣ Add a Button to the screen.
2️⃣ Set the OnSelect property of the Button to:

Notify("Button clicked successfully!", NotificationType.Success)

📌 When the user clicks the button, a success message appears.

🔹 Step 5: Using Notify() for Form Validation

✅ Example: Validating Empty Fields Before Submission

If( IsBlank(TextInput1.Text), 
    Notify("Please enter a value!", NotificationType.Warning), 
    Notify("Submission successful!", NotificationType.Success)
)

📌 If the field is empty, it shows a warning. Otherwise, it confirms success.

🔹 Step 6: Using Notify() with Data Sources

✅ Example: Showing a Message After Saving Data to SharePoint

SubmitForm(EditForm1);
Notify("Data saved successfully!", NotificationType.Success)

📌 After the form submission, a success message appears.

✅ Example: Handling Errors When Saving Data

If( Not(IsEmpty(Errors(YourDataSource))), 
    Notify("Error saving data!", NotificationType.Error), 
    Notify("Data saved successfully!", NotificationType.Success)
)

📌 If an error occurs, it shows an error message. Otherwise, it confirms success.

🔹 Step 7: Using Notify() for Conditional Messages

✅ Example: Checking User Role Before Showing a Message

If( User().Email = "admin@example.com", 
    Notify("Welcome, Admin!", NotificationType.Information), 
    Notify("Access restricted!", NotificationType.Warning)
)

📌 Displays different messages based on the user’s email.

🔹 Step 8: Combining Notify() with Variables

✅ Example: Showing Dynamic Messages Using Variables

Set(MessageText, "Welcome to Power Apps!");
Notify(MessageText, NotificationType.Information)

📌 Stores a message in a variable and displays it in Notify().

🔹 Step 9: Using Notify() in Power Automate

1️⃣ Create a Power Automate flow.
2️⃣ Trigger the flow from Power Apps.
3️⃣ Return a success or error message using Notify().

✅ Example: Calling a Flow and Showing a Notification

If( Flow.Run(), 
    Notify("Flow executed successfully!", NotificationType.Success), 
    Notify("Flow execution failed!", NotificationType.Error)
)

📌 Shows a success or error message based on the flow result.

🔹 Step 10: Best Practices for Using Notify()

✅ Use Notify() for immediate feedback instead of pop-ups.
✅ Limit message length to ensure readability.
✅ Use different notification types to differentiate between errors, warnings, and success messages.
✅ For persistent messages, set timeout to 0 so users can manually dismiss them.
✅ Do not overuse notifications; too many can be distracting.

🔹 Conclusion

The Notify() function is an essential tool in Power Apps for providing real-time feedback to users. Whether it’s success messages, warnings, errors, or information, notifications improve the user experience by guiding actions and alerting users to important events.
