Microsoft Teams Webhook Generating 400 for Adaptive Card

问题

I have a functioning webhook to a Teams channel to which I can successfully post messages. I am now trying to post an adaptive card to the webhook. Using Postman and performing a Post to https://outlook.office.com/webhook/xyz, with Content-Type set to application/json in the header and the following adaptive card set in the body.

{
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "type": "AdaptiveCard",
  "version": "1.0",
  "speak": "Nothing to say.",
  "body": [
    {
      "type": "TextBlock",
      "text": "Hello Teams' user"
    }
  ]
}

With this I receive a 400 Bad Request and "Summary or Text is required" message. Does anyone know if Teams webhooks support Adaptive Cards yet or if this is an unsupported task currently?

回答1:

Webhooks do not yet support Adaptive Cards. We plan to add support for Adaptive Cards shortly after we release them for bots.
