How to create a new Channel in Microsoft Teams through PowerApps


In my last blog, we saw how to post message in channel through PowerApps. In this blog we will see how to create a new Channel in Microsoft Teams through PowerApps. We will add an approval stage before channel creation. Teams owner will approve the channel request and then channel will get created.

Agenda for this blog


  • Build a data connection to Microsoft Teams
  • Make a screen under Screens
  • Create a MS Flow for channel creation and Approval process

Data connection to MS Teams


  • Click View -> Data sources
  • Add data source -> New Connection -> Select Microsoft Teams

Make a screen under Screens


We will add a screen under the screens tab of our application. Screen shot of my screen is below.

Figure 1

In the above screen, I have added gallery, labels, Text inputs and buttons. How to build the gallery control with “Select Team” button ? Add a gallery control in your screen and write “MicrosoftTeams.GetAllTeams().value” to populate the items in gallery. Insert two labels and one button inside the gallery.
Formula for each control inside the gallery are below.
Label10_1 > Text > ThisItem.displayName
Label11_1 > Text > ThisItem.id –> Hide this control as no need to display.
Button1_1 > OnSelect > Select(Parent)
Gallery 4_1 > TemplateFill > If(ThisItem.IsSelected, YellowGreen, White)

Pardon my naming convention of the controls 🙂 . Hope you guys will do it properly whenever creating an application.

Rest controls are just used as it is in the screen. Create Channel button is invoking a MS Flow. If you don’t know how to do this. Please go through this link. Formula for Create Channel Button is CreateChannel.Run(Gallery4_1.Selected.id,TextInput2.Text,TextInput2_1.Text).
