Direct webhooks have been removed but you can still use webhooks to send messages to Teams using PowerAutomate.

It's messier to set and maintain but it works as intended and also you can add more things to the workflow.

If you just want a URL to send json to, the new way is awful. But if you want to have more control, now you can.

Sometimes I like the PowerAutomate way, sometimes I hate it...
