Townhall Graph API : Presenter is always added as in-tenant even as communicationsGuestIdentity

Question

Townhall Graph API : Presenter is always added as in-tenant even as communicationsGuestIdentity

Émeric Trang 25

Hi,

I am implementing the Townhall api.

I am having an issue while adding presenters to a townhall.

I want to an add out-of-tenant presenter.

I am calling the following endpoint : /beta/solutions/virtualEvents/townhalls/$townhallId/presenters

with the following parameters :

                "identity" => [
                    "@odata.type" => "#microsoft.graph.communicationsGuestIdentity",
                    "displayName" => $firstname . ' ' . $lastname,
                    "email" => $email,
                ],

I am having an expected result :

{"@odata.context":"https://graph.microsoft.com/beta/$metadata#solutions/virtualEvents/townhalls('xxxxxxxxxxxxxxx')/presenters/$entity","id":"xxxxxxxxxxxx","email":"******@xxxxx.com","presenterDetails":null,"identity":{"@odata.type":"#microsoft.graph.communicationsGuestIdentity","id":"xxxxxxxxx","displayName":"xxx xxxxx","email":"******@xxxxxx.com"}}

But When I am logging in to teams, the presenters is always in the "Presenters from your org"

Is there anything else to do, or any conditions to make this works ?

Thanks

Emeric

Hi, Émeric Trang,

Based on your description, I understand you're using /beta endpoint. I created external presenter using v1.0 endpoint, but I got the same behavior. When I get the presenter via Graph API, the response shows the presenter is correctly created as communicationsGuestIdentity and probably it's Teams client display issue. If you have to resolve this issue faster, it's better to create an enterprise support ticket.

# Create an external presenter
$Uri = "v1.0/solutions/virtualEvents/townhalls/f5e8ada2-d1da-4191-828e-0d12c353a693@ac2852a6-88d6-4ddc-9a63-93391e191144/presenters"
$Body = @{
  identity = @{
'@odata.type' = "#microsoft.graph.communicationsGuestIdentity"
displayName = "Guest Speaker"
email = "******@fabrikam.com"
}
Invoke-MgGraphRequest -Method Post -Uri  $Uri -OutputType PSObject -Body $Body

# Get the added presenter information
$response = Invoke-MgGraphRequest -Method GET -Uri "v1.0/solutions/virtualEvents/townhalls/f5e8ada2-d1da-4191-828e-0d12c353a693@ac2852a6-88d6-4ddc-9a63-93391e191144/presenters/8b559824-20f0-4010-9e07-5d1679df4afa" -OutputType PSObject
$response
#@odata.context   : #https://graph.microsoft.com/v1.0/$metadata#solutions/virtualEvents/townhalls('f5e8ada2-d1da-4191-828
#                  e-0d12c353a693%40ac2852a6-88d6-4ddc-9a63-93391e191144')/presenters/$entity
#id               : 8b559824-20f0-4010-9e07-5d1679df4afa
#email            : ******@fabrikam.com
#presenterDetails :
#identity         : @{@odata.type=#microsoft.graph.communicationsGuestIdentity; #id=8b559824-20f0-4010-9e07-5d1679df4afa;
#                    displayName=Guest Speaker; email=******@fabrikam.com}

Hi,

Thanks for your reply and confirming the issue.

Indeed, I tested the beta api to make a test, but we do use the v1.0.

Not sure if it is just a "display issue" since I did not manage to connect to the townhall as presenter during our tests.

I'll mention that on my ticket.

Could you please tell me how to create an Entreprise Support Ticket ?

I understand you actually use v1.0 API. You can create a support request from Microsoft 365 admin center as below. I hope this helps.

*If you don't have admin role, please contact your tenant admin first.
