Steps to follow to send messages to Teams:

1)    In Teams, create a channel, then select 'connectors'

2) configure an 'incoming webhook' and record the URL

3) In GoAnywhere, create a REST resource and provide the URL.  Set the data format to JSON and leave the authentication tab blank.  IMPORTANT: on the Connection tab, set Use Chunked Encoding to 'no'.  Save the resource

4) In a project, add a REST Post task referring to the new resource.  Set the content type to "application/json"

5) Use the following for the Content:

{

    "@context":  "http://schema.org/extensions",

    "title":  "YOUR TITLE",

    "@type":  "MessageCard",

    "text":  "YOUR MESSAGE"

}
