Why isn't this a sign-in like Slack?

Teams exposes channel posting through Workflows, not an app install. It's free on every Teams plan and needs no admin approval.

Does this use Office 365 connectors?

No. Those are being retired. This uses Workflows, which replaces them.

In short

Teams connects through a Workflows webhook rather than a sign-in. It's free on every Teams plan and takes about three minutes.

What lands where: Every call posts an Adaptive Card to the Teams channel you chose.

01Open the Workflows app in Teams
In Teams, open the Workflows app — the … menu, or search for "Workflows".
Integrations are available on Starter and above. A free trial can't connect them.
02Create a flow from the webhook template
Create a flow from the template "Post to a channel when a webhook request is received", then pick your team and channel.
03Paste the URL into Ahoya
Copy the URL Teams shows when the flow is created and paste it into Integrations → Microsoft Teams.
The URL is on logic.azure.com or api.powerplatform.com. If what you copied isn't one of those, it's the wrong value.
