Check for existing Teams name, Microsoft Graph?

[OlaH]

At our school we have a form in Power Apps where teachers order Teams for there classes. Before the order is sent we'd like to check if the Teams name already exists.

Could this be done with Microsoft Graph?

If so, how?

Hi @OlaH :

You could try:

Get https://graph.microsoft.com/v1.0/groups?$filter=displayName eq 'YourGroupName'

If the value of Value in the return value is empty, then the group named "YourGroupName" does not exist

Thank you @bo for your suggestion but I can see that I wasn't clear in my question.

I want to see in the app, before the order is send, it the Teams exist.

Hi @OlaH :

You can use this API to get the return value first to determine whether there is a corresponding group.

Get https://graph.microsoft.com/v1.0/groups?$filter=displayName eq 'YourGroupName'

 If the value of Value is empty, execute the command to create the group.

Ok, but forget me. I've not worked with this kind of API before.

Could you please explain how I would use this to show a warning icon (Visible) if the team exists?

Hi @OlaH :

First create a custom connector:

I think this link will help you a lot:

Secondly,Create a button and set it's Onselect property to:

If(
    !IsBlank(MSGraphAppConnector.GetGroups({'$filter': "displayName eq 'TheGroupName'"}).value),
    Notify("The group already exists"),
    CreateYourGroup /*Create Group, use your own formula*/
)

/*'A Talk' is a group that already exists*/
