    Hi @Fernando Zago ,

    I hope this article can be of help to you.

    Set channel registration ID

    The Channel Registration ID GUID was created during channel registration. You can look it up in the portal on the Channels tab of your Azure Communication Services resource.

    Screenshot that shows an Azure Communication Services resource in the Azure portal, viewing the 'Channels' tab. Attention is placed on the copy action of the 'Channel ID' field.

    Assign it to a variable called channelRegistrationId


    string channelRegistrationId = "<your channel registration id GUID>";
