```

2)Body ->

{
    "name":"[TabName]",
    "teamsAppId":"com.microsoft.teamspace.tab.web",
    "configuration":
    {
        "contentUrl":"[WebURL]",
        "websiteUrl":"[WebURL]"
    }
}

```

3)Error->

```
 "code": "InvalidRequest",
          "message": "The navigation bind for the teamsApp was missing in 
               request."

Tabs API is said to be GA already hence I'm posting this question.
