Adaptive Cards + Webhooks
We NEED webhooks to support Adaptive Cards. MessageCards are not flexible enough!

We are happy to announce that we now have support for posting Adaptive Cards via Incoming Webhooks in developer preview!
You can try it out with any of your favorite HTTP request composer tools (PowerShell/Postman/Fiddler) using Message Activity format with https://docs.microsoft.com/microsoftteams/platform/task-modules-and-cards/cards/cards-reference#adaptive-card attachment.
Please keep providing feedback on other features you’d like to see. We will post further updates as we have them.

I was evaluating to migrate some webhooks to teams from slack. Spent few hours to create some adaptive cards but just found they were not supported by webhook, oh no!

I've developed good looking integration into Slack, and the lack of this standard feature continues to drive a poor adoption rate for teams...

Wasted 4 hours designing and generating the Adaptive card...
Whats the hold-up?

Began creating an Adaptive Card, later realizing that it's not compatible with webhooks. This should have been implemented from the start.

You say Bots are able to post Adaptive cards to Teams Channels but the Flow Connectors continue to fail.
I've been able to use and HTTP Action in Flow to post a legacy Actionable Message to a Teams Channel.
If Adaptive Cards is the future then this needs to be supported.

Integrating cards into another software, would enjoy being able to use adaptive cards.
Additionally I'd like to see adaptive cards support messaging to another channel or even team (If it does I have missed it along the way).

even if you write out a bot to handle this, it relies on context of previous replies. there is, by design, no way to take an adaptive card and push it into a channel proactively. really?

+1 to what Martin says... tables are a MUST

Martin Danielsson commented
I either need full AdaptiveCards support, or tables in MessageCards... You can't create tables when connecting with the webhook! That's... a severe limitation.

Being unable to send AdaptiveCards via the webhook connector is something that should have been there from the start

Yes, and the documentation isn't immediately obvious that Adaptive Cards don't already work with Webhooks, only Bots right now. We have a handful of small notification scripts that post to Teams that would benefit from the extended formatting Adaptive Cards provide, but we don't want/need a whole bot for it.
