Hi @IcE-TanK,

Do you want to post Gallery selected item to Teams message?

Could you please share the specific error message with me?


I hope you investigate this connector deeper so that you should know that Message expect an untyped object value, which you need to use JSON to convert it into Json and parse it as below:




Best Regards,

Hi v-qiaqi-msft 


yes I'm trying to send gallery item to a user via teams, I think I'm writing the code in a wrong way,

can you please show me the right syntax?

Hi @IcE-TanK,

I think I have shown you the right syntax, please check the previous reply.

Best Regards,

Hi @v-qiaqi-msft 

i have read the code you wrote above but I couldn't understand what I missed since it didn't show any syntax error at all but of course it's because it reads all strings values as "TEXT" 






MicrosoftTeams.PostMessageToConversation("User: the one wo is sending the message", Location: this is what I don't get :/, body: the content of the message which I'm selecting as the selected current item) 

 and now I'm completely lost XD 


Edit: btw I'm not sending the message to any group or channel, it's only to single user chat...



Have you figured this out yet? Been spinning on this for three days now. Documentation is shyte and apparently no one knows how to do this! It can't be this difficult! 


How to send a message from PowerApps to another user in Teams?  

Frequent Visitor

Wow, it was painful, but I managed to make this work:

MicrosoftTeams.PostMessageToConversation(poster, location, body)

  • For poster, I couldn't get "Flow bot" to work,
  • For location, this is the edited name/title of my chat conversation. It is odd, sometimes it needs to be what I have here, other times, it just needs to not be blank.
  • body - it took a lot of research/troubleshooting to get the format right, then the errors told me that it needed "recipient" and "messageBody"

Hey Matt, 


I actually ended up using the following. It was easy, and it seems to work pretty well.


Paste the following into the OnSubmit button where you want to post a message to a Teams chat: 


MicrosoftTeams.PostMessageToChannelV3("Team identifier here (1)", "Channel identifier here (2) >", {content: "<p>put your HTML here... </p>", contentType: "html"}); 


That's the whole string. Fill it out according to your needs. To get the Team and Channel identifiers (1 and 2, above), I created a new blank screen, and then set up the following: 


1. Create a Gallery (call it Gallery1) and set Items == MicrosoftTeams.GetAllTeams().value

2. Add the following labels to the Template for this Gallery: 

   -- ThisItem.description      ---> This is the TEAM descriptor 

   -- ThisItem.displayName   ---> This is the TEAM Name

   --                     ---> This is the TEAMS ID you plug into the formula above (1)


This gives you a list of the TEAMS you are a member of. 


3. Create a second Gallery and set Items ==  MicrosoftTeams.GetChannelsForGroup(

4. Add the following labels to the Template for this Gallery: 

    -- ThisItem.displayName   ---> This is the CHANNEL display name

    -- ThisItem.description      ---> This is the Channel descriptor 

    --                     ---> This is the CHANNEL ID that you plug into the formula above (2) 


Now you have a list of the CHANNELS associated with the proper TEAM


Combine everything above and you will be able to send messages to the appropriate recipients. 


Hope this helps! 




Hi Ted, thanks for the feedback. I didn't use the MicrosoftTeams.PostMessageToChannelV3 action because I am posting to a chat. As far as I can tell, in this scenario, there is no "Team identifier here (1)" for a chat.


But, now that I think about it, maybe there is an analogous action to MicrosoftTeams.GetAllTeams().value that would give me an ID for all of my chats maybe like MicrosoftTeams.GetAllConversations().value? I will take a look at at some point. Thanks. -Matt

I have tried many things and gave up already, I used the power flow and it sent the notification but with the improper details, i hope to solve this soon enough
