In this blog, you will see how to post to the Facebook timeline using PowerApps. I have created a simple blank app with Phone layout using PowerApps Studio in which I have added a Text box and a button in the screen. I have also added a data source which is connected to Facebook.
Click the button and then enter
Facebook.PostToMyTimeline(TextInput1.Text) for OnSelect property.
![]()
Hit F5. Enter the message and click "Post".
![]()
You can see that the text is posted to Facebook timeline successfully.
