FORMATTING THE
INITIAL MESSAGE

Below is the basic format of the JSON you want to send to your bot to create the initial message:

{
  "activity": {
    "type": "message",
    "summary": "Set this to a summary that you want to appear in the
                desktop/mobile notification in Teams",
    "attachments": [
      {
        "contentType": "application/vnd.microsoft.card.adaptive",
        "contentUrl": null,
        "content": {
          "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
          "type": "AdaptiveCard",
          "version": "1.5",
          "body": [
            // Place all of the JSON for the various pieces of your
            // message here. Use the Adaptive Card Designer and
            // Actionable Messages Designers to figure out the formatting.
          ],
          "padding": "None",
          "msteams": { "width": "Full" }
        }
      }
    ]
  },
  "bot": {
    "id": "YOUR_BOT_ID",
    "name": "YOUR_BOT_NAME"
  },
  "channelData": {
